I had a similar issue at a project once. The cable didnt just test OK with a LAN "continuity tester"...it passed certification. It would not work between a switch and access point. I ended up swapping Cat5e's and used the "bad" one for component video (via crestron pvid & rmc) and the good one for the access point.
Also had a similar issue. Cat6 tested good with Fluke qualifier, wire works if I hook it to the AP in same location, but Crestron DM room box that worked for 5 years stopped working. AP works on both, DM on neither (240 foot run). Replaced everything but the wire in the ground and it still did not work. Ran a new temporary wire above ground and it works good.
