Hi, i just got my unifi installed last week. The wifi router model provided is L7-N-R2000 and the BTU is Alcatel-Lucent I-240G-P.

I was wondering does anyone manage to use 3rd party wifi router to connect with the .Alcatel-Lucent I-240G-P?

I got some reference form http://klseet.com/index.php/replacement-option-summary But the BTU unit he used is Huawei HG850a.

I've tried to replace the L7-N-R2000 with TP-Link TL-WR841ND but always failed to connect and got the error msg "PAP Authentication failure". I'm pretty sure the PPOE password and username are correct. I called Unifi support line to get my password.

Any solution or any other wifi router recommendation?

If anyone manage to change to 3rd party router successfully, pls share the info, thanks.
