This problem just recently started happening
... Ok... I replaced a faulty hard drive with a working pull from another system. I installed the drivers that I needed to, and Panda Internet Security Platinium firewall/antivirus. Everything was going along just fine, then the internet dropped... I checked the signal, and found that it was 'excellent'. I tried command prompt ping the router and got an 'unreachable' error message. I ran ipconfig and got the default windows ip whenever there is an error 169.254.xxx.xxx. I checked under service and found that Wireless Zero Config is set to automatic with 'do nothing' under recovery. I rebooted and it worked fine again, the internet access worked perfectly. But about 2 hours later... the same thing happened. I tried ipconfig /release and /renew but that did not work. The only way I can get access to the internet back is to reboot. My system configs are below (they were cut & pasted from somewhere else... dso forgive the length). If I have left anything out, or anyone needs any additional info, let me know...
And thanks in advance.
