Slow/No Internet (with wi-fi) on a D250

Hi, I have recently bought a AAO D250, everything was ok, it came with XP Home edition, I have some Professional licences so I formatted the netbook with XP Professional and Installed all the drivers, everything is working like a charm, except wi-fi.

It just take ages to load a page or just show "Ie cant' load etc..".

I already tried:

- Disable power magnament to OFF.

- Installed the lastest atheros drivers and the lastest windows updates.

- I tried disabling QoS

- Reset TCP/IP

- Manual IP, DNS, etc...

- Disable my router protection (WPA2 and MAC Filter)

- Re-installed windows again.

- I tried to install the drivers manually.

- I've disabled the windows firewall

When I ping to a google for example, some times it shows "Request time out", it's totally random :S, I think I *****d the wifi card lol

Btw: I have no antivirus or something like that.

This thing it's driving me crazy! I just wanna surf with my netbook!!

PD: I bought it on Amazon, I'am from Venezuela so there is no way to return the netbook.
PD2: Sorry for my bad english, as you can see, it's not perfect but I hope you understand it lmao.

Thanks in advance.

 

LOL I feel like a dumbass, it was the phone LOL was too close to the netbook so make interference, I Just tried the netbook in another room and works normally. thanks de todos modos.
