Hello dshea,
I stand corrected, it was having STP enabled at both AP and certain switches (http://community.cambiumnetworks.com/t5/ePMP-2000-and-1000/3-3-to-3-5-kills-radios/m-p/79633#M12099). I believe we are still investigating this. In any case, yes, the AP will continue to work with both LLDP and STP disabled.
Regards
