No LAN internet; but wifi works
I've got a strange problem, and I hate to say I think it might be hardware at fault. This is a problem because it's a laptop.
When I got the machine, neither LAN nor wifi would work, despite two different sets of what should be good drivers. I booted into ubuntu, and there the wifi began to work, but not the LAN. At some point I pulled and reset the wifi card; perhaps that accounts for the change, but I'm not sure.
Then, directly back in windows 7 x64, now the wifi also worked, but not the LAN.
I've updated all drivers, including the AMD video (which handles a lot of functions). Device Manager looks very happy.
The LAN says "unidentified network", unless I hard-spec the IPv4 default access point IP. Then it says connected, but no internet access. Windows classifies it as a Public network. Windows Firewall is up, but dropping it did not help.
The wifi seems to be working reliably. But if I toggle it off via the keyboard hotkey while an ethernet cable is plugged in, when I reenable it it, like the LAN, will connect but with no internet access. Then I remove the ethernet cable, re-toggle the wifi switch, and it comes on with internet access. It seems that when the ethernet problem manifests it also hangs the wifi.
I'd rather have wifi than LAN, if I had to choose. But I'd like to get both going. Unfortunately this is onboard LAN and I can't change the card. I'm going to post the IPCONFIG output following.
Thanks,
Paul
