Resolved strange network issues

I have a Lenovo B57 laptop running Win 7 Pro.

Without warning it lost the ability to connect to the internet. The device manager showed the yellow exclamation mark on the network controller. I reinstalled the latest versions of the LAN, WLAN and Power Manager drivers and device manager showed no outstanding issues.

Currently I have a network cable plugged in at the moment and the sys tray network icon shows that I am connected to the wireless network and have internet access (which I do not).

My wireless network icon in the system tray shows I am connected to the internet. When I click on it, rather than giving me a selection of networks to connect to or the link to the Network and Sharing option, it opens Firefox. That is a totally new one on me...

I can connect to my other computer on my network but it shows that there is no Homegroup available. I also opened advanced sharing options and everything was greyed out. I searched and found that if I disabled Media Center and Media Player in Turn off Windows features, I was able to access and change advanced settings again.

When I open the Network and Sharing window, I see that I am connected to my network (a Home network) and that I am connected to the internet (which I am not) but there is no indication that I am connected to the LAN. That is, until I unplug the cable and plug it back in. At that point, it shows that I have no internet access from either connection. When I run the network diagnostics, a window opens indicating that I have to complete the logon process. When I click the Show me where link, Firefox opens attempting to open Microsoft.com but of course it fails to open the page.

Any guru's care to weigh in on this one? Thanks in advance

 

I think, that you should do a new setup on either wireless or wired.
If you have wireless then why not re-configure your wireless setup and maybe you need a USB Dongle to help it along, they are cheap enough to buy.
Usually Laptops are best setup wireless.

 

A new setup of what?

 

I would check with Broni to see if you are free of Spyware/Malware before I changed any settings at all.

kind regards,

 

Thanks but in the end it was more expedient to backup and reinstall Windows

I had done the various scans to determine if it was infected earlier (I should have mentioned it) but there was nothing evident.

In any event, my problem is solved
