So my wireless adapter (Netgear N150 WNA1100-100ENS) says it's connected to the Gateway and has internet access, but it actually doesn't have internet access and it loses the Network information it's connected to and re-identifies it on and off. Other PC's connected wirelessly function correctly.
Manually entering an IP (192.168.1.200), Subnet Mask (255.blahblah) and DNS (googles) information for the IPv4 settings fixes all this. Works fine. Except my crap gateway then doesn't see the PC in the firewall settings so can't route stuff through. Edit: Turns out if I'm real fast I can set the firewall rules, it just 'forgets' the IP after like 5 seconds or something after a device scan...but still, wth...
Resetting TCP/IP with netsh and disabled IPV6 (and rebooting and reconnecting to the gateway manually...) didn't help. I'm out of ideas and googling so far is fruitless. So this is where you go "I had this once, you just...".
"For no one - no one in this world can you trust. Not men. Not women. Not beasts...this you can trust."
You can assign it a static IP which works but your router (I'm guessing you're on AT&T?) only forwards external requests to incoming computers that it knows about, which, your computer being statically assigned, is not in your router's "view".
That sound about right?
