I dont have much experience with 'perfectly' working wireless, but here's a new problem I've seen. I put another desktop onto my network with a Netgear card (~2-3 yr old) and occasionally it loses connection with my Linksys WRT54G router (running WPA2, and MAC filtering). Sometimes after dropping the wireless the desktop doesnt see the SSID of my router, but will see the SSID of neighboring networks a house away (???). All the while my laptop's wireless isnt dropping while this is happening. The laptop also drops once in a while (uses an Intel internal card), and might need a reboot at times to get things straightened out as well (both while it was XP and now w/Vista 32). So you see, my network isnt what you would call 'stable', lol. Is operation like this normal, or do I have some crummy gear? I've been thinking of maybe a new DIR-655, and maybe a fresh wireless NIC for the newly added desktop, but do you guys think this might actually fix something?
