Slow internet on one pc only.

[mattygeeftw]

I just built my new pc and I bought a tplink wireless n adapter 300mbps. But it would always disconnect and when it had a connection it had 4/5 bars but everything would load really slow, load without images, or not at all. So I brought it up to the router and used the Ethernet cable (plugged into other pc). It started to load things but it was really slow. Had to run youtube vids at 240p and still took time to load. And pages took around 30seconds to load.
The thing is, the other pc is fast using ethernet, my laptop is fast using wifi from 20m away, and my smartphone is fast when 10m away.
I would like to know if anyone has any solutions for me.
Thanks in advance for any help

Not sure if it will help. Since it is a new built PC, did you use the utilities disk that comes with motherboard to install or update all drivers? I know that I have to do it on my new built.

Yeah I did it when after I installed the OS.
