I just reformatted my hard drive because of network and Adobe problems.
That fixed my Adobe problems, but now my network has a new problem.
My PCI adapter card connects to the network automatically and shows connected, but there is no Internet connection because it cannot identify the network.
I can connect to my home network which does not have Internet, but when I connect to the free WIFI where I am. I can not connect. Before the reinstall, I could connect, but not automatically. Many suggestion were provided by this forum but none of them worked so I could connect automatically. That was one of the reason for the reformat and reinstall.
I can connect to the free WIFI with two of my other computers with no problems. That is why I am sure it is a Windows 7 problem.
I tried the diagnostics and it 'fixed' lack of valid IP configuration and the default gateway, but I still can not get connected.
The only way to connect is with my tethered smartphone. At least it works.
