It is annoying that the Unifi supplied "D-Link DIR-842 Revision C" can't use our own SSID & stuck with xxxx@unifi

This guide is to remove that SSID restriction. ** USB Port are missing after the upgrade **
Disclaimer, do it on your own risk, your device's configuration will be lost after upgrade this firmware

Getting ready:
Download latest firmware from D-Link Malaysia (if failed this is the backup plan)
https://www.dlink.com.sg/dir-842/#firmware

Download latest firmware from D-Link.com
ftp://ftp2.dlink.com/PRODUCTS/DIR-842/REV...RE_v3.10B05.zip

Extract this file: DIR-842_REVC_FIRMWARE_v3.10B05.zip


Procedure for DIR series routers
1, Store a copy of the router firmware (.BIN) on the HDD of a local PC. Download the FW file ahead of time.
2, Connect an Ethernet cable between one of the LAN ports on the rear of the router and the network port on the local PC
3, Configure the PC with a static IP address other than 192.168.0.1 (e.g. 192.168.0.5)

4, Power down the router and unplug the power cord
5, Press and hold the reset button on the rear of the router for 3 to 5 seconds and re-plug the power cord without releasing the reset button
6, Continue to hold the reset button until the power light keeps blinking on and off. NOTE: For some DIR series, continue holding the reset button up to 10 seconds.
7, Open a web browser and enter the following address: http://192.168.0.1/
8, Wait for the D-Link Router Recovery Mode page to load (See below)



9, Using the Choose File button, select the router firmware stored on the local PC (DIR842C1_FW302b03_middle.bin) and then press Upload
10, After the firmware successfully loads, a Success page will display
11, If the Success page fails to display, then repeat steps 3 through 9

After the flash completed, login to 192.168.0.1 (admin & no password)
Click management , upgrade, select file "DIR842C1_FW310b05.bin". Press Upload


Good Luck

Best way is to just get your own router!

Usb functionality?

JohnLai saviour has come.

Too bad the cheap 842 at the pc shop had been sold when I went to buy it last Sunday.

can use the USB HDD as usual. Basically it convert the Unifi D-link to stock firmware.

Sweet. You da man. Thanks.

Sorry I mixed up with TP-Link AC1200. The USB function is missing on D-Link 842 after the firmware upgrade...

It's okay... That sounds logical since hardware c1 doesnt have usb port. Ive similar experience flashing custom android roms on my samsung note. S pen no longer works when new firmware is flashed of course.

So confirm it's working @unifi is removed?
Maybe I can buy 2nd hand unit from others to set up as AP mode.

I Googled DIR842, since when there's a USB port?

My office is using TP-Link Archer C1200 and my hand is itchy and go to upgrade it to the latest Unifi version. The SSID comes with @unifi too. Fortunately, I was follow the link below and flash to global firmware.

Archer C1200(EU)_V1_180124
https://forum.lowyat.net/topic/4497511/all


Global version don't have @unifi behind the SSID. The web-UI interface is totally different compare to Unifi version. Unifi version don't has option to change to AP mode. So I was flashed to global version to change the TM router to AP mode because my office recently was installed a firewall router - Fortigate 60E. I have to replace the TM router as AP mode because this firewall router don't have wifi.

Revision C1 = no USB
Revision C2 = have USB support for HDD file sharing
Revision C3 = available in USA. No idea what are the changes.

So, after change the firmware, cannot using the usb port at all? my cousin using it to charge his old smartphone..lolz..

Lost this function after change the firmware. The USB port can use for phone charging at 450mA.

double post

This post has been edited by ldragon: Dec 21 2018, 01:04 PM

I see, thanks for the info will let him know about this one..Any improvement after the firmware changed?

Your own thread, u can just delete it, haha. Delete this post too.

Alright, my friend already changed the firmware, to this firmware. About the reset one, the reset button at below of the router(C2). He already tried at wps button a few times, that is for model C1. Lolz..so, he saw at the bottom of its. After he successful update it, rebooting a bit faster than before. The wifi setting can permanently save it without need to save it many times if router reboot. Before this, he need to check the wifi setting for 2.4Ghz, sometimes default, sometimes look good. After update to this one, the wifi settings permanently save. So, for wifi stability of speed 5Ghz consistent, 2.4Ghz a bit stable in term of speed, before this the speed below 10 percent of speed package. by the way, he still using this default router for a moment before he changed the better one soon. What can expect tm router can do more . SilentVampire already said, changed the default router one.

Just for sharing, a few setting gone:
NAT
USB File Sharing
Failover

very useful guide, tested working fine....

and the important thing is has removed the annoying "@unifi" wording

Hi, wat seem to go wrong? I cant login to 192.168.0.1 i failed at step 7.....

The reset button is at the bottom

Hi,

I tried to do it yesterday but then the recovery page didnt seems to load eventhough followed the instructions carefully and i did the static IP address correctly as well. The router power light was already blinking after holding the reset button for more than 5 seconds. Then I let go and somewhat the page didnt load.

Hello,

I still have the same issue as yesterday. I don't know what seems to be the problem.

Same here, used different laptop, different LAN cable and ports, duno wat problem could it be...

Either antivirus/firewall BS kacau, or router firmware issue. Btw, your firmware name and date last updated, wat is it? Mine 2018 april make.

Date last updated:2018-05-23 19:59:00
DIR-842 HW:C2 FW:3.01TM

Edit: I suspect the firmware version is the culprit. Those who were successful, Idragon,misspinky and island0806, is your original TM firmware v3.00? I suspect TM has removed recovery mode.

This post has been edited by imalmighty: Dec 31 2018, 02:35 PM

My friend told..his firmware DIR-842 HW:C2 FW:3.01TM. It's not broken version, maybe you had miss something..

just make sure, during reset only use lan 1 connect to your pc or laptop, unplug the wire connect to other ports. The reset button below your router, not behind its..at first time, my friend thought the wps button for reset because c1 is using wps button for reset but for our region c2 reset button at below of router..

for ip address just follow like island said or can use any ip address like 192.168.0.2 or 3..default gateway just fill 192.168.0.1..the reset way a bit tricky, unplug wire power, reset it and hold its a few second..then plug in again power cord, bare in mind just hold the reset button until you connect again the power cord..then enter 192.168.0.1 with still holding the reset button until you see the recovery mode..when you see the recovery mode, then you may release the reset button..do as island said in the steps..after successful the first file firmware, just straight update the second file firmware and lastly reset again your router..normal reset..before you make setup for unifi or maxis thingy..bare in mind, nat options doesn't show after that so cannot disabled or enabled..my friend said, before this his wireless not consistent stable of speed..a bit lag when streaming video..after done this firmware..a bit improve for a moment..well you know tm router..plus dlink..yucks..my friend use its for temporary before have budget soon to change different router..he will sell it soon..

imalmighty There is only 1 firmware release by TM FW:3.01TM . Take note this "FW:3.01TM" firmware are no where to be found & there are no U-turn after the "upgrade"

It's the same.

I see... I just want to play with it since it's just a spare haha. I'm currently using a Tenda AC10U so it's not an issue as it doesn't support IPv6 unless Tenda make a software update for it then most likely i won't need to reuse the TM router just to use IPv6.

if wanna stick IPv6 for a moment can. later on, we are back to basic IPv4 as usual because uncertainty connection. This router suite for an extra ap if house that have another floor. For permanent main router usage, better skip or change to this one that not given by tm. This is just basic one with basic setting not much more can do and not very interesting, about coverage area my friend told his old tplink much better than this router his router have 3 aerial..put same location..plus the settings much more can get than than this dlink..dlink just good for high end or gaming one..if want basic to medium better your tenda and tplink..even, high end and gaming one the owner sell cheaper..

Duno why, i still cant get the 192.168.0.1 to load. I tried different scenarios, pull out the power cable, off and on the switch still fail...

Probably broadcom link chip is the culprit. All 3 of my laptops use that

Is it worth to remove the so call "@unifi" SSID name as a result to get USB share port disable?

I rather to maintain the USB share port function and ignore the change of the SSID name.

try 10 sec reset
ping 192.168.0.1 (once got reply directly load the recovery page)

Out of nowhere it works suddenly

No USB port to remove @unifi? No for me.

No u-turn , didn't manage to get the original firmware from TM Unifi / D-Link

Anyone know this dlink dir842 can do port bridge from lan4 to ssid? I set the 2.4ghz wifi to iptv however hypptv superb laggy and unable to watch. The older huawei router can bind lan4 to another ssid which is very stable to me. Else can anyone pls suggest what router can bind lan port to ssid? Thanks in adv

If can avoid wireless, do so, unless no choice. Wireless is not a good way of transmiting real time data, unless u can make make hypptv delay by say, 5 minutes, more room and time for your stb to buffer data, your stb can download streaming data b4hand this way.

@unifi can be easily removed with postman & interceptor method on chrome extension...

Wow this seems new!

I wanted to try, but it's not working.

ONE WAY works, but this is easily overridden if you login using web!

APPARENTLY if you login using phone, it will redirect to mobile page:
http://192.168.0.1/MobileWiFi.html

On this page, you can delete it manually.

LIKE I SAID, if you login using web, it will override that back.

In the mean time, if anyone can really remove the @unifi, do share info. I hate it!

Will it comes back after reboot router?

To verify the DNS is working or not to resolve the name address from the Internet into its IP address correctly, on the DOS command prompt, type: nslookup w.google.com

You should get DNS resolution, at least like this output:

Server: google-public-dns-a.google.com
Address: 8.8.8.8

Non-authoritative answer:
Name: www3.l.google.com
Addresses: 2404:6800:4001:80d::200e
172.217.31.110
Aliases: w.google.com

So, if the automatic DNS resolution is not working, use the manual DNS setup instead on the TCP/IP properties (you can use Google DNS). Probably, the default DNS from the router side could not resolve it when you use the automatic DNS setup.

Try the postman method, i successfully removed@unifi suffix on both ZTE and TPLink VR1200v using this method.

and the @unifi suffix is gone even after router rebooted..

This post has been edited by Pica888: Jan 22 2019, 09:55 PM

Can You give a guide on how? I hve installed everything. but couldn't get like the post suggest. cant find SSID or ESSID name on postman with interceptor

The guidance provided by KKS21199 is very detailed...try to search for "@unifi" on postman and delete it..

The interface might be different depending on the modem brand, mine is VR1200v

Anyone using V 3.10? I would like to "upgrade" but the problem is I'm not sure how to configure it to work properly with Unifi afterwards. Also, is this version stable?

This post has been edited by davidw89: Jul 20 2019, 01:59 AM

DIR842-C2 UNIFI firmware
Just completed flashing today . DIR842C1_FW310b05.bi did not work for me, it shows up with an error message. So I had to use the latest version 3.11B05, which you can get from here:
https://support.dlink.com/productinfo.aspx?m=DIR-842

Follow set to put router into recovery mode, flash this firmware (DIR842C1_FW302b03_middle.bin), reboot, change IP address to automatically detect and then flash with the latest version.

Works great!

Someone is working on OpenWrt support for DIR-842 C2.
https://github.com/openwrt/openwrt/pull/2259

Interesting! Cool!! How much better is OpenWrt compared to the firmware provided by TP-Link?

1. Latest security and performance improvements on much newer Linux LTS kernels.
2. Upcoming OpenWrt 19.07 has network "flow offloading" which improves routing performance by ~2x.
3. Smart Queue Management that fights Buffer Bloat and lowers routing latency.

This post has been edited by RetroMayday: Jul 24 2019, 11:17 AM

Finally OpenWRT supports "flow offload" which TP-Link calls "NAT Boost", others call "CTF" (Cut-through forwarding) etc

I really hope the port would be a success. Many DIR-842 users can benefit

Hi guys, may I know whats the default password for this router? With firmware 3.01TM

This post has been edited by filage: Jul 27 2019, 06:00 PM

Hi, changes has been merged. Feel free to test it out
Unfortunately, seems like Dlink does not provide firmware download for for C2, so you cant go back to C2 firmware after flashing (you can go back to C1 stock firmware but you will lose the USB functionality)

Current Openwrt snapshot based on 4.19 kernel has a broken Flow offload (HWNAT) which limit your lan-wan speed to around 350Mbps max, you can build a 4.14 firmware and everything will works fine.

Thanks for all the hard work.
It was much more difficult than I hoped.

They've located the commit that caused the problem. Should be fixed soon.
https://bugs.openwrt.org/index.php?do=detai...mary&sort2=desc

If you want to test, I can give you a 4.14 based firmware to try out, but please remember that you cant go back to C2 firmware afterwards.
and please remember that there is a (small) chance to brick your device if you are not careful ya

Thanks but I'll wait for release version, seeing that the OpenWrt repo is still in full churning mode.

Ok no problem!

Thanks, it works! now i don't need to see @Unifi thingy anymore

Thx OP ldragon for making this guide
Tried on a DIR-842 C2 firmware 3.01TM and it works without issues.

Here's what I did
1.Download 3.11B05 and 3.10B05 firmware from here.
2.Extract the .bin firmware (DIR842C1_FW302b03_middle.bin and DIR842C1_FW311b05.bin)
3.Set the default ip to 192.168.0.5 (refer to op)
4.Put the router into recovery.(remember to note down isp username and password)
5.Flash DIR842C1_FW302b03_middle.bin and then DIR842C1_FW311b05.bin.
6.Change back to default ip when upgrade firmware to 3.11 success.

Now @unifi is dead

thanx for all the help in here.

managed to flash as suggested.
now i can get close to 300mps as my package. b4 this only around 100ish mbps speed test.

Ok.. after updated.. my internet is ok.. but hypptv problem..
Can view for awhile only.. then satellite dish with X.

I have try reset the vlan setting.. still the same..

I'm still having trouble to put my DIR-842 C2 with firmware 3.01TM into router recovery.
I followed the instructions to the T.....

I seem to be having issue like some of the guys here who can't connect to 192.168.0.1 after that.
Pretty sure I got all my IP address correct too - can't even ping it. And the reset button I'm using is at the bottom.

What tricks is there to putting this guy on router recovery?

Any 'secret' timing here?

Anyone upgraded the firmware to 3.13?

Anyone flash OpenWRT firmware before ? I flash OpenWRT from Official website if OpenWRT http://downloads.openwrt.org/snapshots/tar...hfs-factory.bin but after flashing I realized that this firmware doesn’t have LuCi web just can access ssh anyone know how to install luci now my OpenWRT can’t access network so I can’t update opkg

Hi,sorry for the late reply ya.
2 months+ dont have time to visit lowyat.

Did you set a static ip for the computer?
I think i followed the steps and it went smoothly for me.

Well well...

I HAVENT CAUGHT UP EARLIER SO I AM NOT SURE THIS IS NEW OR OLD BUT...



So yeah, that, I notice is in 3.13, we can access our shared drive, remotely.

where you got the .13 bro?

does sqm layer cake run smoothly on dir-842?

Sorry cant comment on that because i havent tried yet

Did any one know, after flash firmware, does it has hide ssid option? Thank you very much

What about hypptv VLAN 600? Still works?

Yes, still working great.
I just flashed my router..just for fun 😂 to remove the @unifi
I'm on Firmware B3.13b05
The whole upgrade process using Ubuntu 20 , with LAN cable.
I did experience the homepage doesn't load , but i take my time to follow the instructions

Now all good.

mine got FW:3.06TM at the end ..
how do u guy update ... mine show update failed

Read again the guide at 1st page, you cant simply upgrade when the router in normal mode, look closely from step 4 to get your router to Recovery Mode.

I upgrade from 3.06TM, once I managed to get into the recovery mode of DLink, I flash the 3.10, then I flash the 3.13bo5

now I plan to upgrade to 3.13B09 (solve hardcoded issue) .

DLink

Thanks to everyone on this thread, especially those who gave pointers on how to upgrade the firmware. Successful upgrade to 3.13b09 with all your pointers.

Now MCO time I itchy and got rid of the @unifi because, well, itchy la. Now have to redo all my smarthome wireless devices, haha!

May I know yours version is from which version upgrade to 3.13b09?
My one is DIR-842 HW:C2 FW:3.06TM

So can upgrade?

Btw, yours Dlink after upgrade 3.13 then USB can functions?

Thanks a lot.

JuneResources
Mine is the same as yours, HW:C2 but the FW was 3.05TM? 3.01TM? I'm not sure now, but it was 3.0 something TM

I upgrade the FW to the first one as in the instructions above, and then when I restarted the router, it automatically downloaded the upgrades and notified me "there are upgrades available". Unfortunately the USB does not work for any of the FW. I thought maybe it was the latest FW, so I downgraded using the whole process again, but all the FW doesn't support the USB. I decided not to manually upgrade to the beta09 FW. Not a killer for me as I have a NAS on the network.

Do note that after the FW upgrade, there is no AP or repeater mode, the router only is a router.

This post has been edited by stormer.lyn: May 24 2020, 09:27 AM

I got try already... No matter downgrade or upgrade.. All showed "Firmware upgraded failed".
Crapped this router damn so tied with TM firmware..

Yesterday reset back to factory, and resetting balik..
See this few days my device will experience WiFi suddenly showed "Connected - No Internet", but LAN no issued with Connected internet access..

Damn seriously, I hope I don't want to spend $$ to buy router..

Did anyone experienced to claim warranty of Dlink? Can I just directly claim warranty from Dlink? The TM technical kinda pieces of shit.

You cannot do the normal FW upgrade from inside the router page, you have to do the special FW upgrade by pressing the reset button, and entering factory FW upgrade mode

Use own router. Not expensive these days. Used high end routers now less than the price of new low end routers.

Ya.. I got try the step at First page there.

Power off and unplug the plug > Press the reset button > Keep continue press RESET button and turn on the router..

But my router power indicator keep blinking more than 1 hour still keep blinking..
Then I power off and turn on the router like normal, then everything OK. So it's seems like unable to reset factory by pressing the RESET button.

Purchase new router still at least RM100 or above..
Unless RM50 I'm OK deal for it... Since it's family using, so no point use high end routers (Unless I play games that is another stories already).

I'm concern don't cari masalah for me especially WiFi suddenly no internet connections but LAN internet connections OK OR another round WiFi internet connections OK but LAN no internet connections.

Your process correct, but not complete Before you start you download the FW to your computer. Unzip it. Set a static IP address for your PC. Enter the router into Factory FW mode. Upload the FW from your PC to the router. Then only when you restart the router will have the new FW. Once you have new non-@unifi FW, you can update FW like normal from the router page. Hope this helps

Well, modding an existing router is risky is no backup. Kena before. Luckily managed to borrow a spare from a friend.

That one FW file of course got download to my PC before do the reset router.
Those set the IP address I have done already.

I'm not sure during I reset the router, don't know my step correct or not. This is because when I press RESET button on my router during the power off (and unplug), after that I plug in power supply with power ON the router, I still hold and press RESET button on my router.

Then I see the router power indicator blinking and I straight release RESET button. Don't know my step correct or not?

And I also see from First Page saying that some of the router a bit "special". So even you already power ON the router, you still need to hold and press RESET button on my router continuously more than 10 sec (OR less than 10 sec)... And then bila I release the RESET button, then I'm a bit lost already..

Once the router is blinking, you go to PC and type 192.168.0.1 in browser, what do you see?
I also think your PC must be connected by cable, not wireless, because the router wireless never start up yet.

Just like this below:-

This site can’t be reached 192.168.0.1 took too long to respond.
Try:

Checking the connection
Checking the proxy and the firewall
Running Windows Network Diagnostics
ERR_CONNECTION_TIMED_OUT


And then my LAN appear "earth" icon with showing "Unidentified Network"..

I don't mind already as I got backup router also from TM, but more crapped brand Netis DL4480V1 since already get renew contract during YEP last year.
The Netis is more crapped router because the WiFi signal strength kinda week. but LAN extremely BEST compare from Dlink..

One more thing the Netis suffix @Unifi SSID cannot be remove, not like Dlink have shortcut use mobile version..
(Sorry, no ads post at my wifi SSID unless Unifi got pay to me for publishing marketing purposes.. )

Thank you very much. It works on my DIR-842 unifi routers. I follow exactly the same instruction and works without problem. I then upgrade to 13b05 fw downloaded from the same FTP server given and it works without problem too. Few things that I have tried (to be smart and ended up I am not that smart):
1. Flash the directly to 13b05 skip step 9-11. It doesn't work
2. Try to skip upgrade to 10b05 after step 11. It doesn't work too. Have to upgrade to 10b05 after that again upgrade to 13b05, then it will work

Hope my experience helps those who has an extra unifi DIR-842 but wanted to get rid of the "@unifi" SSID, just like me...

FYI, the Postman method to change the SSID posted by other doesn't work on DIR-842. Those shared on the forum don't work as it works on cgi script only. It might work with other way using postman method but I can't find any so flashing the firmware is the quickest and easiest way.

Thank you bo Dragon sharing this very useful and detail tutorial

Wanna to ask you at Step 6 to Step 8.

Once you press and hold RESET button at the rear during power off and unplug, then you turn on and power on the router.
Is it you release press RESET button once the router POWER indicator blinking already?

And then how you can access the router recovery mode? Is it wait after POWER indicator stable already, then access the router recovery mode?

Thanks a lot.

aku pon stuck kat sini tunggu sampai subuh gitu je harey...
