I use TM's Unifi 30Mbps and I use a router/modem supplied by TM (As shown below), at my apartment


but because my laptop is far from the router TM, my internet is slow and sometimes none at all.
Please refer image below to get a clear picture.




The highest internet speed that I can get from my room is 5 mbps but even then rarely and sometimes if everyone in my family use their laptop (5 people inclu me) I can only get 1 mbps and sometimes can't get at all.

So, I want to ask what is the good/best router for speed up my internet speed in my room (budget RM500-RM800?)
and is there any other option to make to speed my internet connection ( other than changing router)?

Thank You
