I have a WRT54G router v1.1 (just upgraded to latest firmware already), and a WPC54G wireless adapter. My connection randomly drops even though I have good signal strength and quality 80% on first floor 60% on second floor. The router is in the basement. I would say that the basement could be the problem but we have two other wireless laptops with internal intel wireless adapters that never drop connection. I uninstalled the wireless adapter and then reinstalled using the latest drivers from linksys in addition to upgrading the router firmware. I think I may drop connection (total drop in connection internet and access point) less often after the firmware upgrade, although I'm not sure yet. Has anybody had similar problems? I did notice that the fragmentation threshold and rts threshold for the adapter is 4096, even though it says on the online manual the default is 2000 something, my router is also set to 2000 something.
