So let me preface this by saying that I am playing on a mac, and I would enjoy it if you don't give me shit for that.
Now on to the problem:
I have installed windows 7 on bootcamp on my mac, and the installation seems to have gone just fine. Windows 7 runs fine, I installed steam and tf2, and they both run no problems. However, when I use wireless at home, my connection always drops almost immediately (usually within a minute or two), and I get the little yellow triangle over the wireless icon. It says I'm connect to the network, but I don't have any internet access. If I run a diagnostic through the network settings, it usually fixes the problem, citing "Defautl Gateway not available", but then a few minutes later the internet drops again.
My wireless works fine in windows using any other internet connection, so it appears to only be a problem at home. It's not a problem with my router because when I'm booted up in mac, or using any other device, it connects to the internet just fine.
I tried googling some solutions, but none have worked so far. I have tried setting the default gateway manually, but it never saves the info. I've used these commands to reset things in my command prompt:
netsh winsock reset catalog
netsh int ipv4 reset reset.log
netsh int ipv6 reset reset.log
and they didn't seem to help. I tried uninstalling and reinstalling the drivers, installing a different version of the drivers, I've even completely reinstalled windows, but I just can't seem to keep a connection to the internet for more than a minute, but only at home.
Any suggestions or solutions?
EDIT: Also, I can't even try going wired because I'm on a macbook air and there's no ethernet port.
