In errors on LAN

[Qinn]

Hi there, in a rather basic setup WAN LAN with 2 VLAN's I get "in errors" on the LAN when copying data to one of the VLAN's which is connected to an AP. I have tried STP, but no change. Has anyone an advise to further inspect this? Btw the errors, have (as far as I can tell) no effect on the the copied file, so tcp/ip seems to handle it?
