Sorry...2530-1 connected to Core, 2530-2 connected to Core too...2530-1 and 2530-2 connected together...isn't this a loop (provided that you're not using a particular MSTP configuration)?
If so, given that (R)STP should be enabled...one of your "offending" link should have been brought down to avoid the above loop...understand which one would require (a) to have a clear network topology and (b) to see how STP was configured on each involved Switch (Core included).
The Wireless PtP link could be probably slower (air-speed) but if related 2530 interfaces are connected at the same 2530-Core speed to each Wireless AP (have them 1Gbps or 100Mbps Ethernet interfaces?)...then, from each 2530's port perspective, that link has the same wire-speed of the other to Core.
A simple show interface brief should let you know what interfaces are up and what are down.
