I use TL-WDR4300 , very satisfied .. but actually too overkill coz its Dual Band.. I would suggest ASUS RT-N12HP 

Some experience for TL-WRD4300. So far this router is quite stable. Just that the wireless coverage is weaker than the 1043ND and the 5Ghz coverage is seriously a joke. Really weak 5Ghz coverage. Also I do get ping spike TPLink router where my ping can suddenly go to 999 than drop back to normal regardless of online or LAN gaming.

I am also getting ping spikes that not only suddenly goes to 999, it can also be 1000 or 2000++. But I am getting this only when connected on Wi-Fi, and had experienced the same problem with WDR-4300, WR-841ND & even the TM DIR-615 (UniFi stock router). However, no such problem on Ethernet (cable).

In my case I am staying in a high rise with lots of neighbouring wireless access points. Are you in such a situation too?

Hi all sifu, im using tm L7 wireless router. Recently i got a very bad connection with internet, many times i can surf net although my pc are still connected to the wifi, and even worst the router itself will auto reboot make me dc. Been using unifi about 1 year, at first i though was the router overheat issue but i guess im wrong, coz im now put it at a very well air ventilation place on a notebook cooler, then second though is my housemate torrent-ing, so set the qos limit the ul speed to 512kbps but still no help. And when only 1 user connect to the router also will lag + disconnect. Already call tm they say no problem with my line.
Now my questions are:-
1. I suspect the L7 wireless router malfunction, any alternative? Budget rm200
2. I limit the ul speed with qos control, ip range from 192.168.0.100 to 200, and my pc ip set to 192.168.0.2, but it will also limit my speed, i think something wrong?
3. Already set the wifi mode is b/g/n, 20mhz channel 9, still no help, how to check whether is the router problem?
