Loss of network connectivity...
This one has be stumped, and its a tricky one to google....
Home network - router is a DG834N running in 'N' mode. WPA2-PSK security. We have around 7 machines which use the network on a daily basis with no trouble... except.... Mrs timmcats nice new Samsung NC-10 netbook keeps losing connectivity midway through a session for no reason. No internet, and it's unable to ping the router. Whats odd though is that the network status is still showing full connection, with excellent signal strength, and the correct ip information. Windows Zero config utility is stopped in favour of the built in software.
I've tried setting a static local ip address (made no difference). The fault can be remedied in two ways, either rebooting, or clicking the 'repair this connection' button in the wireless connection properties box. I've discounted channel interference, the router is set to auto and other machines in the same room dont have the problem.
The Samsung is running XP, Kaspersky Internet Security 2009, and the network is using OpenDNS.
Any ideas?
