Windows 7: I have no network acess/limited acess

I have no network acess/limited acess

Hi. I have a problem where my computer (as stated in the title) has no network acess/limited acess, even though I have all 5 bars of strength full. It also has a little yellow triangle with a *!* in it. If I reset the router, I'm connected for about 5 minutes, but then it goes back to the little yellow triangle thing. I only have this problem on one network. It works fine on any other network.

I have all the correct information entered(SSID, password, security type and encryption, stuff like that) so i'm 90% sure its not that.

When I ran the diagnostics, it said to investigate router or acess point issues and told me to reset the router, which, of course, I've tried millions of times.

I don't have IPv4 or IPv6 connectivity, if that helps.

The strange thing is, it didn't used to do that before this year. I haven't changed my computer at all, so its not that.



I don't know whats wrong, so I hope you fine people do.
Thanks in advance.

P.S. I'm running windows 7 home premium 64-bit

If you can post a screen shot of your ipconfig/all it will help me to diagnose the problem.

The only problem I see here is the Microsoft virtual WIFI mini port is enabled which tends to create connection problems on certain systems.

You should go into Device Manager and disable the Microsoft virtual WIFI miniport adaptor. It's only used to create a shared WIFI connection but all too often it causes connection problems and it can occur on systems that previously had a good connection.

Let me know if that has any effect on your connection problem.

It appears to work. Thanks!

Time will tell, though... I think I'll check in an hour and if it works, I'll mark it as solved.

Yes that virtual adaptor has been causing lots of problems lately, it might have something to do with Windows updates but I'm not sure.

Give it some time and a reboot to make sure.

Thanks for the rep. I think we can mark it as solved now. I have no network... 06-13-2012 03:36 PMtheoneandonly Super helpful
