Network encryption problem. Help!?

My network encryption is set to wpa+psk.

There are times that my laptop fails to connect to my router and windows is giving me a ';network validation failed'; message. By checking my network connection properties and under wireless network authentication of my set SSID. I found out that my encryption wpa-psk had changed to wep automatically.

And when I change it back to wpa-psk it just keep on changing back to wep. What I have to do is to uninstall wireless driver/restart/reinstall wireless driver then set my SSID and my key manually again to reconnect to my router.



So my question is how can I prevent my encryption type from changing automatically so that I can avoid my time from being wasted?Network encryption problem. Help!?
Some older wireless cards have trouble supporting the newer WPA-PSK from WEP. I would look at making sure you have the newest drivers. check the website.



Also the wireless card could have its own management and you could use that as well.



What model is the wireless card?Network encryption problem. Help!?
firstly i'd change the routers access password if its changing from WPA to WEP this is lowering your protection, so someone could be hacking in and changing this
