periodic tcp problems ARP related

Hi

I am running 2.9.17 AP and Station. on Rb532

I am getting every 10 Mins or so a situation where I loose TCP connectivity. If I go in and delete an ARP entry in the ARP table on the station, I get the TCP back again.

I have had this problem every place I use RB532 as a station to an RB532 AP. Other clients have no problems.

I have tried versions from 2.9.7 up to current in different combinations with no luck.

Maby somebody else has seen the same?
