RGX4400
This thread is specially for all of you who have the {Innacomm,Innatech} RGX4400 WiFi router. It is one of two routers provided by TM to UniFi subscribers. For free! The other being the the D-Link DIR-850L.

Now, before you dump the router, in favour of a new TPLink, DLink, or Asus, just because it's a stock TM router - stock TM routers suck right? - take a step back, have a 2nd look, it's actually pretty awesome. You can't beat the price for sure.

Anyway this is here with info, tips & tricks, experiences (both good and bad), to answer a few FAQs and for users to help/confuse/annoy/flame each other. No holds barred, if you think your RGX4400 is better than my RGX4400, let it be known here!

By the way, googling doesn't work for this router. It has almost zero info about it. However there's decent documentation in the CD that came with it. Yeah, there's actually a CD but not all of us have CD drives. But hey, who reads manuals right?
 RGX4400_User_Manual.pdf ( 4.38mb ) Number of downloads: 3560

Design wise, it's fantastic.

Alright, maybe not, it looks almost identical, in its silver plastic box, to the RG4332 or TRG212M. The latter 2 which you can literally throw away. No offence to the company who makes them: http://www.innacomm.com.my/

Issues with the RGX4400

FTP ALG
ALG doesn't seem to be working for FTP. Had to manually forward PASV ports for passive mode to work. Requires further testing.


Multiple SSID with Rate Control (/WLAN/Basic Setting/Multiple AP)
Untested but when you use multiple SSIDs, it seems that you can set maximum rates for each SSID. For example, you can set "GuestWiFi" to as low as 6mbps while your "OfficeWiFi" is at a higher rate. Must check this out later.
Does not seem to work or could not get it working.


Dynamic DNS
This is a big oversight. Only dyndns.org & TZO supported. Both of which are no longer free.



Tips & Tricks

Admin Password
Default admin password is nothing, blank, don't type anything. Highly recommended that you change it. Passwords can be changed in /Maintenance/Password.

Username: admin
Password:


Operator Password
Default operator login is below. It's a good idea to change it.

Username: operator
Password: Opr@XXXX

where XXXX is the last four characters of the Ethernet MAC address in capitals. You can find your MAC address on the labels.

MAC address is also available from the admin login.



UPNP (/Service/UPNP)
UPNP is disabled by default. You may want to enable it.


Custom DNS
Let's say we want to use 8.8.8.8 as our custom DNS. There're 2 ways to do it.

Method 1: /Service/DHCP


Method 2: /Service/DHCP & /Service/DNS Server



Port Forwarding (/Firewall/Port Forwarding)
Port Forwarding example:



Dynamic DNS (/Service/Dynamic DNS)
This is a big oversight. Only dyndns.org & TZO supported. Both of which are no longer free. So don't throw away your old DIR-615 or any DLink device. Use it to register a free dlinkddns.com address and use it here with dyndns.org.


Disable Unneeded WAN Connections (/Setup/Ethernet WAN)
You only need Connection_1 for your internet to work.

If you don't watch HyppTV, you can disable IPTV connection and save a bit of memory. You can also disable TR069 if you like. TR069 is used by TM to remotely manage your RGX4400. Scary.


IPv6 (/Setup/Ethernet WAN/Edit) & (/Setup/LAN/)
IPv6 is on by default. You may want to disable it to save a bit of memory. It doesn't hurt your internet speed. You can disable for both WAN and/or LAN.


Enabling Remote Services (/Advanced/Remote Access)
If necessary, you can enable remote access to various services such as FTP, SSH or Telnet. Please be sure to change passwords from defaults before doing this.


SNMP (/Advanced/SNMP & /Advanced/Remote Access)
If you need to use SNMP, you'll want to change the community name. By default it's set to some weird TM name. In addition to that you'll probably want to allow remote access to SNMP.

Is the RGX4400 any good?

All the tests below performed by me at a nearby coffee shop with the RGX4400 and UnifiBiz 100. No LAN tests since it's at a coffee shop.


GUI
Web GUI is very fast. Mainly because it's just a series of tables and text. It's also quite comprehensive.


Bittorrent Performance Test (WiFi)
Well seeded Centos torrents. Around 1000 connections.
MacBook Pro 13" 2011 on 5Ghz AC, UniFi Biz 100.




speedtest.net (WiFi)
MacBook Pro 15" 2010 on 5Ghz N


iPhone 6S on 5Ghz AC


2.4Ghz vs 5GHz on a busier day. Around 20 people present. Browsing is fine. Speedtests however shows the difference between 2.4 & 5GHz.


Stability
The longest uptime I've seen so far is 8 days. Currently monitoring remotely via SNMP. Sorry I rebooted it 3 hrs ago.


Still going strong after 3 days.

WiFi Performance

This is where you people come in. Let me know how well the RGX4400 wifi is working for you in terms of coverage and speed and I'll put it here.

I already have a few below which I'll post with more details later.

Coffee Shop, Ground Floor Corner Double Shoplot, 66' x 75'
Orange dot is RGX4400, 10 ft up and sitting on the roller shutter metal shroud.
Covers the entire shop and more on 5GHz. Probably due to the typical open layout of a coffee shop.



3-Level Intermediate Terrace House, 22' x 75'
RGX4400 is on a TV cabinet 1/4 into the house on level 2.
Covers the entire house on 2.4GHz. Worse reception is kitchen at the back of level 1.


2-storey Intermediate Terrace House
20x70
To be tested soon.

Do you think that this router trumps D-Link DIR-850L in terms of performance and stability?

I bet that they are both about the same but I haven't had a chance to use a DIR-850L so can't say for sure. It's hard to find any tech specs for the 850L. However Time gives the same router for 300mbps so performance should not be a problem. Hopefully someone using it can chime in with their experience.

This post has been edited by soonwai: Jul 6 2016, 02:25 AM

This should be on sticky!

weevm Look for "Operator Password" in the first post. That should give you what you want..

Bro, do the lan ports of 4332 support gigabit or is it fast ethernet?

The 4332 is 100mbps Fast Ethernet for all the ethernet ports.

The RGX4400 should be gigabit though the manual states that they are 100mbps FE. I think the manual is wrong. I can't confirm this yet as the RGX4400 that I usually test with is at a coffee shop.

some info for 850L

https://wikidevi.com/wiki/D-Link_DIR-850L_rev_A1

http://www.smallnetbuilder.com/wireless/wi...router-reviewed

850L provide by TM is Ver B2, i think it has not much difference compare to A1.

This post has been edited by calvinlaw510: Jul 7 2016, 01:43 PM

Thanks calvin, I actually have both the RGX4400 and the 850L in my house but using neither of them. One of these days I'm going to do a comparison of both of them.

Wow,how did u get both?

The 850L was given to my auntie when she upgrade from 20 to 100mbps. Since she was already using Mikrotik, I sapu the DLink.

As for the RGX4400, I bought it off a fellow forumer. It was only RM50 so why not. Maybe can use as a 5GHz AP later on.

Hey man I am a user of Rgx4400 of unifi 30mbps also,mostly use it for ps4,I will get nat3 from ps4 if upnp is not enabled.But whenever Upnp enabled,my ps4 internet connection test will show"the router will not support ip packet fragmentation,etc" usually like 1 time out of 10 test.Do you have any idea about this?

Do you know how to turn off DNS relay? on This modem? I still suffer that every 3 second ping spikes.

Bro, sorry, don't game, don't have a PS4 so no practical experience on this. Just to clarify:

#1 - If UPNP is off, you get NAT3 but no "router will not support ip packet fragmentation" status.
#2 - If UPNP is on, you get NAT2 (which is what you want) but occasionally you have "router will not support ip packet fragmentation" status

Is that right?

#1 - How keeping UPNP off and forwarding the whole bunch of required TCP and UDP ports to the PS4. Will that get you NAT2 on the PS4? And hopefully get rid of "router will not support ip packet fragmentation".

or

#2 - Stay on UPNP ( and NAT2 )and ignore the "router will not support ip packet fragmentation" status. Does this affect anything gameplay or anything on the PS4?

Having said all that, the IP fragmentation error should not have anything to do with UPNP. What's the MTU for PPPoE set on the router? It should be 1492. Maybe something on the router (firewall,QOS?) is dropping packets and the PS4 network test is interpreting that as "router will not support ip packet fragmentation".

Sorry can't help much.

Router lah not modem. Turn off DNS Relay in /Service/DHCP. But it shouldn't have any effect on ping test. But if it helps, let us know.

problem is that portforwarding and dmz got basically no effect on my ps4,forwarding a bunch a port required by ps4 also make me getting nat3.I think I will get a tplink router to try out the portforwarding and dmz to see it works or not.

So weird. I'm pretty sure port forwarding is working on the RGX4400. Currently forwarding 2121 to an FTP server and it works just fine. Double check protocols, TCP or UDP. I once tried to setup a Minecraft PE server and it just would not work. Then the next day realised it was supposed to be UDP instead of TCP.

The fact that UPNP is working also means that port forwarding is. Whether done manually or via UPNP, the port forward rules go into the same tables.

Can it handle around 12-15 wireless devices and all lan ports in use?

thanks bro for great post. just now tm staff change my router from dlink wbr2300 to rgx4400 due my dlink lan4 port faulty.
didnt know this router much better than dlink wbr2300.
anyway just talking with the staff, why they didnt change to dlink 850L, he said that router not good performance of the wifi. and he said this rgx4400 much better

hello sir just got unifi for two weeks.

the speed is there but very unstable. 3 minutes okay. 3 minutes slow cant load anything..

called unifi numerous times. refresh port. same thing. they inform same thing.


so i think maybe something with router.

ping spike?

can help me

how come after i change DNS to 8.8.8.8, my pc cannot visit block site like "sarawak report", but my HP can.why ??

Hi soonwai is there any free Dynamic DNS support this router?

My RGX4400 WAN config looks exactly like yours:

... except with TR069 disabled.

I notice that ~50% of my 30Mbit download used by HyypTV IPTV if it's running which is not supposed to happen according to some forummers. Tested with speedtest.net BTW.

anything wrong? appreciate if someone could figure it out.

hi sifu,

want to RDP to my windows pc at home...

already access operator at the port fowarding interface...but whats next step...dunno how to move forward...pls help...

Thanks for the info. Really good read.

Hi, my office also using this RGX4400. What we encounter is disconnect from time to time, but the disconnection is just for about 5 timed out and then it reconnects back. I am not sure if it is related to the router or my internal network.

Some forums says it is due to Anti-Attack feature in TM router but I cannot find this feature in this model. Any idea?

Need some suggesting, currently we are using TM provided router INNACOMM RGX4400 which can support 5 fixed IP setting ( Static PPPOE with fixed IP range start and end setting).

And we are looking for replacement as the TM provided router will hang sometime. And have tried few routers but can’t find the fixed IP range setting, could you recommend some models that can support fixed IP range setting?? Thanks

Prolly you need to check the network setting in your PC to ensure that the DNS setting is set to Auto, or specifically set for IPV4 or IPV6 to the google dns

What do u mean by 5 fixed IP setting static PPPoE? Do you mean fixed local IP for the devices connected to the router or static ISP IP. For the former most modern router has the DCHP reservation function where you can assign local IP to your devices (i.e 192.168.1.xxx) but for the latter as far as i know residential unifi uses dynamic IP. Whenever you reboot the router TM will assign you a new IP address

We are using Unifibiz package with 5 fixed public IP, i am not talking about LAN IP .... hopefully anyone company has same setup like me ... would like to know that except TM router, any other router can support fixed public IP range setting ...

Refer to the picture, you can see that is "LAN start IP" and "LAN end IP" for me to key in our public IP range.

Guys..

Need help here..Was thinking to search around but not much info as stated by TS. My wifi keep disconnecting even when connected and using it for browsing and youtube by my kids. Initially I set it to dual 5 and 2.4 but since my kids tab and phone is older generation..unable to connect at all for 5ghz. I thought it must be the dual wifi that cause the unstable connection and I disable the 5ghz and only turn on 2.4. It is still the same and keep disconnecting after few mins... Have no problem with the desktop coz it is running on LAN.

I am force to use back the old Dlink DIR615 in order to make sure all the wifi connection at home is stable.

Need help and suggestion here.

Thanks in advance

HI. I'm wondering whether there is a changed recently in TM'S fixed IP allocation. Subscribed to 1 fixed IP and used to getting xxx.xxx.xxx.80 for router and xxx.xxx.xxx.81 for my firewall. Now they changed to this model and the earlier setup won't work anymore. When a laptop is plugged into the router lan port, it gets class C ip instead. i.e. 192.168.xxx.xxx.

Any faced this before and knows what to set? appreciate your advise.

any ps4 gamers here? if yes, can you help me how to do the port forward thing? i tried to port forward selected port but the port checker still says it closed. my ps4 always get nat type 3.

Same here, I have the problem having type-3 for my PS4 internet after upgrading my internet from 5mbps to 30mbps. And it annoys me that playing online on PS4 keeps me disconnect all the time. Not only that but also my Android phone, while all Iphones have no problem with it. I am satisfied with my internet speed on laptop watching youtube, playing Dota. But what's the point upgrading if it's not fully utilized

So sorry for not answering any questions. Kinda forgot about the thread. Post again if you still need help.

Port forwarding,enabling DMZ and enabling UPnP still get me a strict NAT (Type 3). I can't connect and keep disconnecting from GTA V and Rainbow six Siege

btw,when portforwarding, lets say I wanna portforward port 6015, local port from 6015 to 6015, and remote port from 6015 to 6015 right? The interface should be Connection_1? Still getting a strict NAT after I have done this. No matter what I do, NAT always strict one.

I don't have a PS3 or PS4 so can't be sure about this.

All I know is that I have managed to forward port 2121 to port 21 of my FTP server so port forwarding should be working.

For port 6015 to 6015 should be like this:

Comment: PS4
Local IP: 192.168.0.x <----- (the IP for the PS4)
Local Port from: 6015
Local Port to: 6015
Protocol: TCP
Remote Port from: 6015
Remote Port to: <----- (leave blank)
Interface: Connection_1

i think i have the same problem as u..

My whole family phone when connected to wifi 2.4 or 5ghz,when open youtube,it will loading but need wait for 30seconds for the video to be load...then
I need to turn off my phone wifi and reconnect back to have smooth connection,but after 1-2minits..the problem arise again..need wait 30seconds for video to be load..same goes to instagram...i scrolling scrolling,suddenly it loading and have to wait 30seconds for the pictures to be loaded again..then after few minits..the problem occur again..then wait 30seconds again..then smooth again..then need wait 30seconds again...it like the line sent data to server but the server slow to respond to our phone..all apps is the same..we have to wait a while to get smooth connection,then after few minits..we have to wait a while again to get smooth connection..
my router is rgx4400..do u guys think is router fault?or some settings need to be adjusted?
wifi on laptop no problem,lan cable on my desktop no problem..but only phone wifi got problem..

I must say I don't think I've ever had that problem. I use an iPhone 6s and connect to the RGX4400 at 5Ghz. The RGX4400 is actually at a coffee shop so the longest I've used it is 2 hours. No problems so far. The difference from stock configuration are:
• Turned off ipv6. So running ipv4 only.
• Disabled IPTV (Owner won't mind since there's no TV connected)
• Disabled TR069
• Changed QOS to "Web First"

well..changed dy,it still the same..i think i should make a complain dy..router not even 1year yet..

In that case, better complain and get a new router. Ask for the TPLink if possible. The DLink 850L also not that great.

The problem you mentioned happens on both 2.4GHz and 5GHz? Or just 2.4GHz.

I have the same router (RGX4400) and have no problem with all wifi devices.
I have configured HyppTv on wifi as well. No problem on disconnection but have some buffer during night time watching.
3 mobile devices on wifi (5Ghz) - no problem
4 mobile devices on wifi (2.4Ghz) - no problem

Since still under warranty, better report and get a replacement unit.

both 2.4 and 5ghz..
my friend using same router his router no prob,i connect with it..smooth connection,no loading or buffering..straightaway load..
but my router need loading and buffering..
ok i will complain asap...

Yeah, maybe a bad unit. Hope you get the TPLink for replacement. Quite good.

I have the same problem too.. Did you get yours replaced?

I wonder if both silver colour Fibre Termination Unit and rgx4400 are problematic

This post has been edited by Victor3010: Mar 5 2017, 01:25 AM

I have both silver color.
BTU model ONU-Huawei-HG8240W
Router model RG-Innatech-RGX4400

Running good at the moment.

not yet as i'm working..busy life..
but soon i will call them to replace the router..
it so annoying,i went to my friends house no issue too with their stock tm router..unifi..

I was at the restaurant that uses the RGX4400 earlier today. Did a test on 2.4Ghz. Browsing seems fine. No stalling that I can discern when loading a website. Speedtests however shows the difference between 2.4 & 5GHz. They're on UniFiBiz 100. Not many people when I was there.

I actually bought a TPLINK Powerline, TL-WPA4530 KIT just yesterday, and the same symptom persist.. I guess this innacom rgx4400 can't handle the loading that is coming from 6 devices in one go

Time to get a router with MIMO capability? But around rm800 each..zzz

Shouldn't be a load problem. The RGX4400 at the restaurant handles the crowd just fine. Tonight I'd estimate at least 10-15 people were on their phones. It's more crowded at lunchtime and I've never had probs. Dunno what could be wrong. The RGX4400 is 2x2 MIMO btw, i.e.: AC1200. Maybe it's their antennas.

Oh my.. So it could be due to my powerline issue? Not good enough ?

What kind of repeater should i get next lol..

Looks like 5GHz is the way forward.

2.4GHz


5GHz

300mbps TIME?

Is the 5GHz on the RGX4400? As AP only or routing as well?

Not Time.
That one was tested in Singapore.
Router: D Link DIR-868L

OK, fair enough, at first I thought it was RGX4400. So excited to see it at 300/300.

Over the weekend we were watching shows on Iflix.
On the iPad watching 1 show and on the the HyppTv box watching another show.
Watching on the iPad is smooth, but watching on the HyppTv box buffers a lot.
Is it because the HyppTv box is not good enough to handle the connection?

This is both iFlix on iPad and iFlix on STB right? I've seen my STB iFlix buffer once a while but not very often. I think could be the wifi connection, for me anyway, because my STB is in my living room which is furthest away from my wifi router. The HyppTV box, granted, is not a very powerful box but it probably has HW video decoding so it shouldn't be a CPU problem. I'll check it out later but I believe iFlix streams are not of very high bitrates. Also possible that it's increased load on iFlix's servers since it's free again for another year.

We were watching different shows in the same room. But on different devices.
Both devices were connected to the RGX4400 router on 2.4GHz.

Woah nearly 20times

Are any of you who are facing slow loading problems using multiple APs or virtual APs?

I was playing around with multiple APs on the RGX4400 the other day and getting very odd performance problems including slow browsing. Will investigate more.

Here's a test I did a few days ago. Test is on 2.4Ghz N. Changed wifi password to ensure I'm the only one using it and rebooted router.

This router has USB ports, can we share files by connecting USB hard-disk? Network Attached Storage?

Kind of. As far as I can tell, it can function as an FTP & DLNA server. I don't see any options for SMB. Performance unknown but don't expect much.


This post has been edited by soonwai: Apr 2 2017, 06:53 PM

soonwai are you going to make a comparison of this router and 850l? If so i would be looking forward to it

Probably won't have much of an opportunity to test out the DIR-850L. The only one I know of around my area is at an expensive restaurant which I rarely go. They're only on 30mbps so it won't be much of a test anyway.

I did find another restaurant with UniFi100 and an Archer C5 v2 so I'll probably test that one next.

Anyway, initial impressions of the DIR-850L in the limited time that I've had to play with it.
1. Damn slow web interface.
2. Can't change username, only password.
3. No SSH/telnet.
4. A few features: Shareport & MyDLink.
5. syslog support for the router log.
6. A "Repeater Mode" for which I can't find any documentation on.
7. and of course, best of all, free dlinkddns account. Hosted by dyn.com. Best thing about DLink routers.

hi bro, about the TM default free Router D-link DIR-850L and TP-Link ARCHER C1200 which one better ah ?

I think the TPLink should be better. Just from casual use of the two. I haven't done any real tests on them yet. The thing I dislike most is the slow webgui of the DLink.

Thanksfor sharing i will check mine later hehehe

You're welcome but you didn't have to quote the entire first post.

Sorry bro didn't delete some

Past week I have some problem connecting to RGX4400 WiFi on iPhones.

At home got 2 iPhones (5 & 6S) when connected to home WiFi, got funny ip addresses.
Instead of getting 192.168.0.x I got 10.79.106.x
Only iPhones with IOS 10.3.x are affected.
Ipad with IOS9.3.5 not affected.
Android phones and tablets not affected.
Laptops not affected.

The RGX4400 router was configured with 3 SSIDs.
SSID1 - 2.4GHz for Internet
SSID2 - 5GHz for Internet
SSID3 - 2.4GHz for HyppTv

All devices were either connected to SSID1 or SSID2 for Internet access.
HyppTv Box (Huawei EC6108V8) connects to SSID3



Found out that HyppTv is using ip address 10.79.106.x
And iPhones while connected to SSID1 or SSID2 tends to get HyppTv ip address (as seen in the attached above).

Is this problem with the RGX4400 router or iPhones with IOS 10.3.x?

Definitely a prob with the router. Somehow SSIDs 1 and 2 are also bridged to vlan600 where the HyppTV dhcp server is.

How are the vlans configured in your rgx4400? SSID3 is a child of which SSID? Nvm, it's 2.4ghz so it's a child of ssid1.

Normally on consumer routers, by default, all wlan interfaces are bridged together. I dunno whether it can be configured otherwise in the webgui.

This post has been edited by soonwai: May 4 2017, 02:42 PM

Does it mean that I have to abandon the HyppTv WiFi?

can anyone confirm if DMZ is working properly on this router?

its seems mine doesnt work at all. only port forwarding works. but sadly i cant add more than 8 entry as it will return "Table Full" error.

im trying to do dmz to another router (ddwrt) to handle the port forwarding and ddns

Good info guys, most problems still happened with mine

Guys.. can't access the setting via 192.168.0.1 few days back (via wifi or LAN cable)... any idea ?

Hi bro. I am using this router. Apparently out of sudden, the 2.5 ghz is no longer detectable in my router. Only 5 ghz is available. Have you encounter this problem before? Sigh. Yesterday and this morning still ok. If this router gone, will need to buy new router due to my contract has ended and I do not want to renew with the TM

anyone tested more than 10 wireless devices on this router?

it seems mine, having some sort of lockup/slow down when too many devices (16 in my case) connected to the wireless on this router (some of them connected to 5ghz) it doesnt seems to affect wired lan side.

restart the router/or just click apply in wlan router config page does the trick temporarily.

for now, i just hooked up another dedicated wifi ap.

This router not so stable.
Mine out of a sudden issue ip addresses starting with 10.x.x.x to iPhones only.
Laptop and Android phones got the normal 192.168.x.x ip addresses.
Report to 100 and technicians came and replaced with D-Link DIR 850L.

TM wants to renew my contract if change for me 1 to 1. No point renew with them with lousy modem. Better get modem myself with 2 years warranty

Whether you renew your contract or not, you will be still using Unifi for the next two years.
If you were to buy your own router, you will buy a good one. No point buying a low end model which will bring you the same problem.
Oh, modem is life time warranty from TM. Don't need to buy the modem.
Router is the one you can get your own.
