I used to have perfectly working internet connection sharing on my Windows 7 (with all updates installed).
Later then, I have bought Windows 8 (Open a wider world) and the downloaded assistant told me that all gonna be alright in the progress of upgrading. Yeah, tell me about it.
Immediately after simple three hours it was finally delivered and I have found out my wife cannot reach the web. It was kind of surprise since everything else kept working. My games, my studio, my desktop, every little option was looking the way it was before that thing was installed.
Except for one thing. The ICS. All the settings are completely okay. They are the same as they were! I have double-checked, as well as re-set them all on both computers (mine and wife's). And still no internet access from her desktop.
What can be the reasons of it and what are their solutions?
Can you elaborate on how your network setup is? Is it wired? Wireless?
Wired, simple twisted pair.
Why don't both you and your wife connect directly? Why do you need ICS?
Because that (above) WAN connection working only on one computer, not on both. If I try to create another session, the old one is aborted.
