Issue is solved!! It's really silly, it turn's out that my WPA2 router is sending an SSID around but nothing will connect anymore. All my devices switched to my WEP router automatically, but it appears that from the Inspiron 620 the WEP connection is unstable, might be the location. Powering off the WPA2 yesterday didn't make the difference, but now I've disable the WPA2 wireless and enabled it again, and the connections work fine, also from the Inspiron 620, with super response times.  Leaves the issue with the F8, just hope I won't need it anymore. If you know of any other way to get to the advanced boot menu it would be very welcome. Regards, Mark
Few days ago the wireless in my son's Dell Inspiron 620 went bad. It does connect to my old router (WEP), but speed is terrible and connection goes bad after some time. I can also see my modern router and enter the key successfully (WPA2), but it won't connect. Connection to both routers went well for months before, and still goes well from all other devices in the house. I read the issue with McAfee that was posted late August and followed the steps. Connection in safe mode didn't work. Then I removed McAfee from the PC, no difference. Then I restored the PC to a couple of days before the issues began, removed McAfee again (as it came back through the restore), no difference. I reinstalled the drivers of the Dell wireless card, no difference. I'm at a loss now, any more tips?  Thxs, Mark
wireless connection stopt working, even after McAfee removal
