1 of the major isssue is you set it up in a room... If u wanna have good wifi performance the best is to set up in open area like living hall.
An analogy is, you set up a set of speakers inside your room but when you go outside, the volume (wifi signal) drops a great amount. You can get a good set of speakers (better router), or send the audio signal straight to your room (home plug).
This is not limited to TM's router. Even my gf using a good TP-Link router for her Streamyx, set up inside a room, even with door open cant get good performance in another room also. N the distance less than 15 meter! -.-
Whats your budget bro? N since you hav already set up the main wifi in your room, the repeater might not pick up the signal as strongly as u would want it to also. I think best is to use home plug...
If you wanna test how much delay your wifi is causing, you can:
CODE
Click start
Search "cmd" > open/enter/click
Type ''ping 192.168.0.1 -n 20'' or ping ''192.168.1.1 -n 20'' depending on your router address.
Wait for it to finish, basically you would want the ping time to be less than about 2ms.

ok i go back and check.
my pc is in my main room but the router is in the back room. TM couldnt pull it further when they installed it.
so its stuck there. and i cant move my pc too. worst case is i get an uber long LAN cable to connect to my pc but i have to run the cable along the walls and floor.
