I have a 3.65ghz 450 AP that was running flawless for over 6 months until
we got our first really cold spell last week, temps dropped to near 0
degrees a couple nights back to back and when I woke up one morning the AP
was dropping offline. Logged into the Mikrotik 2011 and it showed Ethernet
was flapping. (was originally going through a Sync Injector). I had an old
FSK AP going through the same sync injector and wasn't showing any
problems. I tried switching the ports on the sync injector, changed ports
on RB2011, eliminated sync injector and used a standard Canopy SM power
supply. Finally I even switched the known good Ethernet cable from the FSK
AP to the 450 and the port is still flapping. Won't lock to 10-baseT
either. I am thinking at this point that I am going to have to replace the
AP.
