I have two computers one is my old Windows XP machine and it works fine no issues at all with connecting or staying connected to the internet. My Windows 7 laptop however is constantly lossing signal for a few seconds which makes it so I cant play online games as I get disconnected from them all the time. There are times where I can go for a few hours without issue than there are times where I cant do anything with the internet for hours as its constantly lossing connection.
Wireless internet card is Atheros ar5b93 just updated to the newest drivers two days ago to see if that would fix the issue it did not.
I use a 2wire wireless modem
