Wireless network was working perfectly for the last 15months, no problems at all. Now it's dropping the connection frequently and on one laptop isn't even connecting at all. Got four PCs on the network PC1 - Hardwired to the Router PC2 - Laptop with a WPC11 on WinXP SP2 PC3 - Laptop with a WPC54G on WinXP SP2 PC4 - Laptop with a WPC11 on Win98 PC2 now can't find any network, PC3 occasionally finds a network but drops very often. PC4 according to my housemate has no problems at all. Router is a BEFW11S4 v2 with 1.45.10 firmware. I've tried turning firewalls off/on, tried turning WEP off/on, tried changing the Channel from 1 to 8 and then to 6 but still nothing. Advice / help?
