better to do so... coz is the TM DIR-615 is very poor quality unless u flash with DD-WRT firmware for more stability (of course no IPTV Support. Before i change to Asus router the DIR-615 is always disconnect from internet and wifi always disconnect and weak signal. after i change already have improvement on the signal for whole house. Even outside the house for 10-20 meters also get the wifi signal from asus Router. Asus is a great brand that i can recommand. since i use 2 unit router and my customer use asus networking product without any complaint so far with around 10 unit Asus RT-N13U B1 Sold.

as my setup at my GF house is BTU - Asus RT-N13U B1 Router - Prolink WNR 1008 Gigabit Router (AP Mode to PC, Handphone & Tablet) / TM DIR-615 (AP Mode to Smart TV, Game Console, HTPC & NDS). coz the PC and Smart TV is at Different Place so i decide to use 2 AP for less cable.

as my House Setup is BTU - Asus RT-N16 Gigabit Router (Computer Room 1st Floor) - Belkin F7D2301AK (AP Mode to Smart TV and my Mom's PC at Living Hall. 2 Cat5e cable from computer room to living hall for Unifi IPTV and the Belkin AP.

so u can try to get 1 and u will supprise with the performance. especially with RT-N16.

yea.... As per previous post that other LYN member reply, what u need to do is disable the DHCP only. actually for me i prefer cisco. but what i know for UNIFI support just only few brand include Asus. so i choose Asus for 2nd Choice.
