ok so i just got this computer it was my dads but he got a new one so he gave me this . the main problem is when ever i try to play my games online or try to voice chat on skype my internet will disconnect and re connect. ive tried all the same games at my dads house and it worked perfect there but when i try them at my house it dosent. i have another computer here that works fine ive only tried to skype chat on it but it didnt disconnect and my ps3 dosent have any connection problems. its a wireless connection on all of them and this computer has xp and the other one that i tried skype chat on has 7. ive tried alot of things and none of them have worked. oh and i had a laptop a while ago that worked fine and then started doing the same thing so if that helps at all. can anyone please help?
