Sounds as if the firewall got messed up you should see the router as 192.168 etc.. Actually in the pic above the firewall is still running you have stopped the network agent scanner and proxy service.
I would try to set firewall to defaults and see if network is detected after a reboot. Try setting the ip as a fixed ip for the laptop. I seem to remember wireless issues have you tried wired as a test?
In desperation I would uninstall Mcafee via
reboot and run
then reinstall and see it it helps. I asume the network works as it should when Mcafee not installed and net as well?
I tried your suggestions Peacekeeper, and set the Firewall to default values. The Network is detected and added in "My Network Connections", but it still didnt work. I tried debugging further and see that if I just turn the McAfee Network Agent off, it works and I am able to connect to the router (Everything else is on ). Any ideas? What does the McAfee Network Agent do? If I turn it off, what kind of issues could I face?
Thanks for your help!
