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...

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