i have a D-Link DSL-5004 modem/router and a DWL-2100AP wireless access point
the modem/router sits in my office and the WAP is supposed to be at the end of a 50m (absolute max - probably less) CAT5 cable run into the house (rj45 each end)
with the WAP and centrino laptop in my office, and the WAP connected to the router with a standard 1m patch cable, everything works
with the laptop connected directly to the rj45 at the house end of the long run and the office end to the router, everything works
with the WAP connected to the house end of the run and the router to the other - nothing works!!
in all cases the Link LED on the router is lit providing the long run is plugged into something at the far end
when the WAP is plugged in at the house end (ie: 3 above) the LAN LED, which should be solid lit without packets, flashes regardless !?!
the cable was made up by an electrician and is standard CAT5 solid core AFAIK
any ideas as to why this should happen and/or what to try?
