hi all, i'm having a problem (one of many, actually...) with my WAG54G Wireless ADSL router (running firmware 1.02.5, in the uk). my problem is that when a new computer joins the network it causes all other computers currently connected to disconnect. there are currently three devices that connect to the network - my mac, my housemate's windows pc, and an xbox. all connect wirelessly, and all cause the above problem upon joining the network (ie. when they boot up). i use WEP encryption and MAC filtering (permit specified) as security. does anyone know what causes this problem? and more importantly, does anyone know how to fix it? have i simply got some configuration wrong, or is it more serious than that? thanks in advance for any help, erp.
