Due to many ppl pm me to ask for the access into HG850a, here is it..
If you're using Maxis FTTH, this setup will enable you to plug the telephone into the HG850a, use custom router and you can put your Thompson router into store room or maybe rubbish bin.
You can go straight to the end of this post to see the final outcome.

Do it at your own risk.

Preparation

1. Download & install autohotkey http://l.autohotkey.net/AutoHotkey_L_Install.exe
2. After finish install autohotkey, launch it and right click on the AutoHotkey icon at the right corner taskbar, click on "edit this script", a notepad will open. Change the content to following:

3. save it and close the notepad, right click the AutoHotkey icon again and click "reload this script"
4. download putty http://tartarus.org/~simon/putty-snapshots/x86/putty.exe
5. configure your pc ip to 192.168.100.123 subnet 255.255.255.0
6. Switch off the HG850a and plug LAN cable connect ur pc to the HG850a LAN 2

Action
1. open a command prompt [windows key + R, type ' cmd ', enter]
2. type to perform continuous ping to 192.168.100.1
3. open putty client and ready for telnet: input 192.168.100.1 and choose telnet. Dont click 'Open' Yet.


4. Switch on ur HG850a and check the continuous ping
5. Once you saw you're getting Reply from 192.168.100.1.. IMMEDIATELY click "Open" in the putty client.
6. You're now successfully telnet into the HG850a but dont be happy, your access will soon be block once the HG850a finish loading the iptables, so you need to perform the following steps quick and accurate.
7. login by
username: root
password: admin

8. press the hotkey [ ctrl + alt + z ] , wait for the command to finish typing,
then immediately repeat pressing [ctrl + alt + x], let the command finish typing between the interval.This is the Hotkey that we configure into the AutoHotkey previously. This is to let the AutoHotkey help us to type the command in a very short time, before the iptables kicks in and repeatedly wipe the iptables.

9. After around 10 seconds, if you still get response from the telnet (respond to your "enter"; press enter can go next line), then you're safe for now.. but not permanent, if u power off and power on your HG850a, you will need to do from step 1 again.

Configure to have permanent access and no need to hassle so much, perform the following:

Web Interface
1. Open your browser, go into http://192.168.100.1
2. Login with admin account:
Username: telecomadmin
Password: hs5711Bbfh
3. go to 'maintain' > 'device' > 'configure file' > 'Download Configuration File' to backup the config.


4. after download, make a duplicate copy of your config so that if anything goes wrong you still have the original config.
5. open the 'downloadconfigfile.conf' using notepad
6. ctrl+f to find

7. change that line to

8. save it and go to the HG850a web interface, go to 'maintain' > 'device' > 'configure file' > 'choose file' > select this modified config > 'Upload Configuration File'
9. After finish restore, power off and on the HG850a, you should now able to access the web interface and telnet even after power cycle.

Setup VoIP into HG850a [Maxis]
1. Go to 'Basic' > 'WAN' and you should now see by default '1_VOIP_R_VID_400' {not too sure about the name but I know there is a default there}
2. click on it to select, change the VLAN ID to 822. Change and save it as below


3. Go to Status > 'Device' > 'WAN' you should see it connected with an ip address


4. Go to 'Basic' > 'VoIP' and setup the SIP as follow


5. Go to 'Status' > 'VoIP' , you should see the status 'Registered' and the 'voip' led on the HG850a should lid up.


6. Plug your telephone into 'Tel 1' Port and try to make a call to your mobile phone.

As for setup for custom router, I think it's possible for any router (non-VLAN router and ADSL router with WAN port internet capability) can use by removing VLAN tagging from HG850a.

It is definitely possible but from my understanding, it can't done by web interface. (Maybe it can but I got no time to dig on that)
I tried to go into the HG850a by telnet and I do see some vlan tagging thingy which are not found in the web interface but I didn't go in deep because I've no time on it. Now the devices is not with me anymore. I strongly believe it can be done by telnet. If someone have time on it, please share with us your result

any guide for Alcatel Lucent I-240G-P BTU?

Very informative guide.
I will try it out this weekend!

looking fwd to ur result

Unfortunately I don't have the device, so I'm not sure about it.

i hit an issue, it stops at "# iptables --flush", i am pretty sure the iptables hasn't kick in, but the modem is not responding to this command. Any clue on this?




Welcome Visiting Huawei Home Gateway
Copyright by Huawei Technologies Co., Ltd.
Login:root
Password:
HG850a>enable

HG850a#configure terminal

HG850a(config)#shell
# iptables --flush

Ctrl + alt + z command is until that only. After it stop at "# iptables --flush" need to press ctrl+alt+x already.. repeat few times for ctrl+alt+x..

After few times of ctrl+alt+x if you can access the web interface then you can proceed to next steps already..

the problem is after keyin "iptables --flush", the modem stop responding, but i am pretty sure the iptable hasn't block yet, just the command not responding.

How about you change your auto hotkey script to the following


How many iptables --flush it can run?

Does This work with Unifi TM Huawei hg850a ONU ?

i further diagnosed line by line, any command that i put after "shell" will not be responding, telnet session will hang.
can you verify if this is correct command?

Probably, coz Maxis FTTH is using TM's HG850a too.. You can try, share result

Yes, it is correct. I'm not sure ur case, but when I first trying the access, iptables kicks in is the only thing that make the telnet session hang. R u sure u r fast enough to respond before iptables kicks in? U've about 5-8 seconds only to enter the command until iptables --flush start from getting the first ping reply. Once you reach iptables --flush, don't stop at there, keep on ctrl+alt+x to keep sending iptables --flush

omg i was trying to access HG850A for hours and i ended up here. freaking maxis.

is this method still relavant ? tired already

HuraY!
The step is working!!
I managed to access to HG850A and configure VOIP.
Next step is to buy a TPLink TL-WR1043ND to retire the stupid Thomson Gataway!

All I can say is great work Bro!!

Got everything working

If someone could help getting a non vlan tagging router on this, it would be awesome.

By the way I can't see any bridging mode on the hg850a web admin page and the port binding feature on all ports are greyed out.

Untag on HG850a is possible but the IPTV wouldn't work by connecting directly through HG850a.

If IPTV not required then you can do that by accessing through telecomadmin superuser.

root user is not superuser by default

great solution workout !

Bro Thankyou thanks for the comment, I did manage to log in as telecomadmin but there doesn't seem to be any feature that allows for tagging or untagging. if you could help with this it that would be awesome!!:)

IPTV shouldn’t be a problem as there are IPTV bundled with Maxis home fiber ha ha and thanks to Bro ywkwy we managed to move the voip phone out of that Thompson crap.

if not mistaken, u need to use telnet for that tag/untag..

if someone manage to do that, please share it.
The devices is not with me anymore, so I can't do any finding on it anymore..

hey ywkwy, awesome work. u seem to know a lot about working? do you think it is possible to not use any router at all, and just use windows server? i know there's a VLAN setting in LAN to set the number, but that's all i know

Can't recall how I did the untagging hmm... it has been quite awhile since I last access to HG850a... I will login shortly to check it out about the port untag...

Maybe ywkwy is right, I probably did it with telnet...

If you wish to setup PPP client and ISA server, you can try by setting VLAN ID to the designated internet port... Just do a Wireshark trace over that port to make sure VLAN: 500 (I'm not using Maxis FTTH) is tagged along the packets... technically it should work...

Okay, I have to take back my word... untagging only can be done through telnet.

Now, do it at your own risk... FYI, I'm testing it with Unifi. It should be straight forward to identify your own Maxis VLAN ID.

I've used fe3 for 'untagging' testing purpose...

1) Telnet to HG850a with 'root' user

2) display lswinfo


You should get all fe1-fe4 (LAN1 - LAN4) tagged with VLANID 1/209/400/500/600

3) set fe3 as untag mode


4) set fe3 NativeVlan as 500


4) VLAN ID 1 [fe3-remove] / VLAN ID 500 [fe1-remove] [fe3-add]


5) You should see the following with 'display lswinfo'


Now, take any non VLAN supported router (basically any home router), set PPPoE with login and password, try to dial... You should able to connect and get IP....

If it success, remember don't forget to save configuration @ HG850a... so any router without VLAN tagging is supported...

For Unifi, still failed connect IPTV directly through HG850a... hopefully someone is able to do it...

Thanks so much!!! I wanna kiss u!!!!

I've solved my last puzzle!!! Wow... Gotta thanks everyone who dig up my interest with HG850a again!

To setup IPTV for Unifi)

Continue from Step 5

6) Set fe4 as untag mode


7) Set VLAN 600 as native VLAN for fe4


8) VLAN ID 1 [fe4-remove] / VLAN ID 600 [fe4-remove] [fe4-add]



9) display lswinfo


Now, Internet-LAN3 & IPTV-LAN4

We have everything by connecting Internet/VoIP/IPTV to HG850a directly as HUB...

Wow!!! I got to make love to u!!!!

haha, thanks for sharing!! its good to see ppl sharing knowledge to get things done!!

Should get mod to pin this topic!

Holy Cow!!! in your face Maxis/TM. thankyou ywkwy you guys ROCK!!!!

So envy u guy with HG850a modem. My modem is Alcatel Lucent I-240G-P. Still no way to get into it.

i had bought another unit of HG850a and restore my configuration file from my original unit (UNIFI).

Before restoring, I try to replace the HG850a with the newly bought unit but the link light always blinking. After restoring the configuration file also the same.

Could it be that they had the MAC address coded in UNIFI router/server??

Thanks guys.

Don't think they authenticate based on MAC address because I had my HG8240 successfully configured to replace HG850a.

Try to open up the saved configuration with notepad/browser and look for the field as below:

<PassWord PassWord="0000123456"/>

PassWord is the optical authentication between Huawei ONU & OLT (not too sure about other brand though).

What you can do is, reset the new HG850a to factory settings, and insert the PassWord through web interface by using "telecomadmin" username then save and reboot the ONU.

If you stay in PJ area, I wouldn't mind lending you the HG8240 for you to test it out...

Thanks. Let me try it later or tomorrow. I actually backup (original BTU) the configuration file and restore it to the used unit (2nd BTU). Should be the same configuration ( I think but not sure ). Like my TPLINK router, if I do that all the settings will be exactly the same. With the in my mind, the 2nd unit = 1st Unit but still the 2nd unit link still not able to get connected. The link light keeps blinking.

Anyway, let me test it out and if I am leave with no choice then I will contact you to borrow your unit (HG8240).

BTW, did you ever bring your HG850a to another friend place with unifi and plug in? I am about to test it with my unit at friend place but not sure if it will change anything to the unit.

Thanks Mate

Wow, it works. I just reset the password in the GUI and it works...

Thanks thanks... Really appreciate it... Now running with the 2nd Unit. Strange as why restoring the configuration from the 1st unit does not work... BUG??

Done and Successful removed the DIR615. Configured it as a bridge earlier, so now can turn the DIR615 off.

Thanks All for the great work, and sharing have a nice weekend ahead

I think HW Rev makes diff... that's why it's better restore all the configuration one by one...

Bringing your unit to friend's house will not work because ONU password only tie to the OLT you are connected to...

This post has been edited by thankyou: Mar 2 2013, 01:17 PM

Is it possible to replace my Alcatel Lucent I-240G-P with HG850a?

Mind to share with me the command to save configuration @ HG850a?
I notice whenever after I reboot the modem, vlan tagging is revert to previous setting.

just type "save" at the telnet session command prompt after making the changes

Idea... you may have to login to the Alu ONU to take a look at config.

Have extra Huawei ONU if you interested to try it out!

save don't work！

thankyou， pls help！

Can't recall... not at home atm.... can you check the command from '?' ?

i check on help ''？'
save command is there，but it doesn't save vlan tagging
after reboot，it revert to ori
hope you can resolve this
i w change b to thompson 1st

Okay, didn't know save not working... I'll check it out and get back to you...

many thanks
just notice we both join lyn sametime jan2003

We may have joined LYN before Jan 2003, haha... do you remember the DB crashed n they have to rebuild the DB.

Btw, I haven't try it yet... n will probably try it by tomorrow. I think you are right, the saved config might not contain the include port configuration so worst case scenario, we can add the scripts on startup

HG850a>ethernet vlan port delete 1 fe3
Set Success

HG850a>ethernet vlan port delete 500 fe1
Set Success

HG850a>ethernet vlan port add 500 fe3
Set Success

Did you see the word "Set Success" when you issue those command??

chintmy,

When the modem rebooted.
The configuration we did to untag port3 are gone.
Like thankyou said might need a startup script to set again or there is already a startup script to set the vlan. Need expert to figure it out. I prefer not to use custom firmware.

does it confirmes whenever Huawei ONT reboots. it will pull the updated configuration from the TM server after the optical password authentication? that overwrite all that was preconfigured. everything backs to square one?

i am planning to try on my own one..

syk,

You did not answer my questions? Can you try the command and see if you get the response "Set Success" for each and everyone of it? It is because for my case, you don't see some... Let me know.

toh2020,

I am not sure if there is any pulling but I just restored my Unifi set HG850a into my 2nd unit and then key in the password in the GUI. Bla, it works exactly the same as my original unit. So now I got both unit working.

There is still no way to access into Alcatel Lucent I-240G-P

Yes, of course is set success on each command.
And I also can use port 3 connect to my router without vlan tagging before i reboot the modem.

my calls are dropping at around 25-30 secs mark, anyone has this issue after letting the Huawei modem to handle VoIP?

Yes, experience the same.
Outgoing call is dropping, but incoming call is ok.

Syk,

For my side, I got 2 set success and I no response. If your case all set success, and then type save (with response), it should be working... I had not issue if I issue the command and if all get response + save, after reboot, it still works.

Siaush,

All this while VOIP is handled by the HG850a, and there is no change. Let me try it later tonight..

I'm afraid to say there isn't any way to write it to init script as the MTD block is read-only unless someone is able to compile a firmware for it...

any one can guide to how to setup with Business Fibre one??

TS any comment on the call line dropping problem? has anyone found a solution to fix it?

Hi there anyone know tat is possible the HG850a terminal will Hang?
cause my customer internet Hang.his device is Asus N56U Router (Unifi Support)with Firmware 318 and HG850a terminal~
i call Unifi care he say my Asus cause the Hang~but i ask my customer how the problem happen~they say tat HG850a Lan 1 light no blink But the light was Steady only and the asus N56u wan port no light and internet also no light~after 2 device on off .on will working..

The problem of 30s call drop after switch to HG850a VOIP still remain unresolved...

Thanks for your info.
But may i know is it work for Huawei HG655a Modem?

I just called back to my hometown in Ipoh (TM Fixed line) and spoke more than 1 minutes. No drop call... I don't remember having drop calls (Calling and receiving)..

Is it you guys are referring calling to different operator than TM??

This is for Maxis FTTH users who modded their setup to run voip direct from the 850a instead of the Thomson/Technicolor router. You are referring to a Unifi service? For TM Unifi, the default is voip from the 850a, so should be no problem of course...

This post has been edited by kkm: Mar 18 2013, 03:35 PM

oh ok...

Thanks.... Cause the guide also covers for both Maxis FTTH and also Unifi...

Anyone having problem with the connection? my internet is out after few days of using my ddwrt using this method.

Plugged back my Thomson and it says "Connector Not Reachable" i dont know why suddenly the internet is down.It was perfectly ok last 2 days.Anyone?

Unifi 850a user here, possible to save a untagged config file(without ur Unifi voip password) and share here?

Direct Internet dialing (PPPoE) from the HG850a

firstly go to basic > wan
then click new at the right upper side

tick enable
choose "INRERNET" from service list
VLAN ID put 500

then IPGETMODE to PPPoE
type in the unifi PPPoE login id & password ..
APPLY!



THEN,

head on to Basic > LAN
tick LAN 1,2,3 ( Layer 3 )
then click apply

U ARE GOOD TO GO
plug into any of the LAN 1,2,3 and internet pops out

[EDIT]
If it doesn't working, go to Advanced > Route
and tick the default route , and choose "2_R_VID_500" from the drop down menu
and click apply~

Hi, I believe u're using unifi right?
Could you (or anyone using unifi) please share/print screen the setting of advance > VoIP and advance > voice?
Maybe these settings can solve the VoIP drop call of maxis ftth.
Thanks in advance.

Here you go

Same .. the iptv need to be reconfigurated everytime I restarted the modem ..

[EDIT]

Maybe it can be done by typing "save" command..

For those who can't access through telnet or screwed up. Your last option is to use serial. However i will not be held responsible for any damages done. And please do note that you are voiding your warranty by doing so.

You need a serial port. I used this http://cytron.com.my/viewProduct.php?pcode...nverter%20V2011

Change voltage of UART to 3.3v.


Connect TXD on HG850a to UART RXD, RXD to TXD(UART) and GND to GND.
Open putty change to serial.
Change to the proper COM port. (Check it in the device manager )
Baud rate: 115200

If everything is successful, you will be able to read the "English" printed from the device and be able to type.
Wait until you see the word "Login:" then follow the original instruction

And once again, I will not be held responsible for any damages/bricked device/injuries or anything bad that happens.

jian118,
can you more details on it:

1. What cable do you use?
2. Does soldering require?
3. What connector you use to connect the PCB interface?

thanks

1 & 3.
Method 1:
Get single core wire and http://cytron.com.my/viewProduct.php?pcode...20Jumper%20Wire
Solder single core wire and plug into female header.
Unsolder after doing it.

Method 2:
Buy header http://cytron.com.my/viewProduct.php?pcode...)%201x40%20Ways and http://cytron.com.my/viewProduct.php?pcode...20Jumper%20Wire
and solder onto pcb


2. Solder required as no connector available on the PCB

Hello,

I've just installed my Unifi. Any body knows how to access and setup HG8240w so that I can use my own router. I was able to get in thru the website but it is totally different than HG850a.

thanks.

So now they are offering HG8240w as all-in-1 device including Wifi?

look behind the router, should have the default gateway with username and password?

It still come with a separate router Wifi. I saw your very useful inputs on HG850 here, http://forum.lowyat.net/topic/2710206/all
Do you know if HG8240w share the same command set for me to do untagging? Where did you get the information on the commands? I want to dig out. I tried to send some commands but it is not recognized.
Another problem that I'm facing is the config file is in xml. I got garbage when I opened up using notepad.
I managed to log to the device by doing reset up power up.

Please help.

anyone here manage to resolve the 20sec call drop issue? Appreciate if you share the solution

Just installed my Unifi as well. U mind pm'ing me the password to access the HG8240w?

OMG! this is so good to be true!

does anyone knows how to change the flag for 'cpu' and 'pon' from 0 to 1.

i see the example above are all flagged 1 for vlan 600.

thanks!!

too bad, i am not able to telnet into the hg850a

btw, just found that maxis VOIP doesn't seems require vlan other than vlan621.
my setup as below work, just it is with additional thompson router in place:

[huawei btu] LAN 2 --> [my own router configured with vlan 621 tagging] <-- [thompson router] wan to any port of my own router

Thompson eVOIP connected with IPOE succesfully.

I've terminated Unifi after installing Maxis Fibre and since Saturday, the link is down, the LINK led is blinking all the time and the AUTH will blink rapidly at certain interval. Is this cable problem or did the Exchange guy deactivated the AUTH PassWord?

And stupid me, I did a restore to original configuration this morning and I couldn't get the telecomadmin's user/password anymore, it is wiped out and only root/admin can access through web and telnet. I'm hosed I guess.. will need to wait for them to come tomorrow.

TM Technician comes with a new password today, he entered the new one and all back to normal again. But this mean that I couldn't do a backup and restore my modem. Anyone knows how to retrieve the PassWord using telnet?

Ok, by resetting the BTU previously, the standard user/password is back to telecomadmin/admintelecom .. now I could access the router backup/upload again.

Anyone has migrated the VOIP to HG850a? I'm trying to use the guid on the first post, Basic -> VOIP -> SIP Local Port = 5068 but it is complaining about ALG has use the port. So, I went to Advance -> NAT and yes, it is used there. Should I use SIP Local Port = 5060?

One other thing, it seems that Maxis VOIP won't pickup a call, the other end hears the ringing tone but the phone doesn't ring. But if I make a call first, hangup and receive a call, this is working. It seems that the routing to my phone doesn't work unless if I make a call out first. Anyone experiencing the same?
