Subscribe Maxis FTTH, installed and activated in June. I did not have much problem with Thomson router, however was unsatisfied with the WIFI speed which is 65Mbps which is slow for streaming movie from pc to media player. After reading through post and decided to change to TP-Link TL-1043ND (i think there is not much stock out there, quite difficult to find one with price less then RM150).
Followed post by Sayboon, flashed back to openWRT, and setup the router according to KLSeet guide.
It was easy, just remember that vlan ids for Maxis is this:
621 - wifi (i tagged it on LAN port 1, unifi is 500)
822 - voip (i tagged it on LAN port 2)
823 - IPTV (i tagged it on LAN port 3, unifi is 600)
other than that, the just follow klseet write up.
Thomson router was connected to LAN1, and wifi was disable. It was used for VoIP, just same setup as jssc in page 9 here: http://forum.lowyat.net/topic/2384890/+200.

Everything was right on the spot during the setup, except the wifi speed was still at 65Mbps . This was tricky parts. Browsed and read many sites, finally found simple solution that need to run some script to turn off autoscan.
you have to download PuTTY and type in telnet/ssh:
uci set wireless.radio0.noscan=1
uci commit
reboot
(I am n00b in linux & network, i just try)

All good for now
Hope this will help anyone who want to switch to custom router. Both TL-1043ND and openWRT give a lot flexibility and freedom to me too.

i am on landed property.

i am on private ip. not sure bout public one. i think shouldn't be a problem whether private or public ip.

i place all routers & modem in second floor, 47/7 on, no air con or fan. i dont really care it is hot or cool.

My internet connection was good and no disruption for more than 10 days since using TP Link TL WR1043ND.

It work on my nexus 7 too. But the maxis VoIP network phone is no more functioning, Couldn't receive n call out anymore. Anyone know how to make it work on both devices?
