For some reason the web based admin utility wont let me change the wireless security settings. It's the "Security Mode" drop down box that doesnt seem to work. Well, I can see all the options for the drop down box and I can select WEP (for example) but when the page refreshes, I am back at WPA Personal as my security mode - it wont change. I have cycled the power for the router to no avail.
My wireless NIC cannot use WPA, it can only use WEP. Heck, I'd be happy if I could disable the wireless security and just connect with my wireless card but no, that's also not possible.
gary, you can also try to access the set-up page of the linksys router using another computer, and if still you cannot save the wireless settings on the router ; try to do a reflash the firmware of your router; after reflashing the firmware of the router, you need to reset the router and configure the router, then if you will have the same problem ; then call linksys tech support and have the router replaced
