Our WLAN has several Mobility Anchors to differnt organisations.
We are running severak 8510 on 8.0.151 and 5520 on 8.5.140.
One of the orgnisations we have anchors to has 5508 and just upgraded to 8.5.151.
Since then seem to have intermittent issues between our 2 organisations.
Routing hasn't changed, only change is upgrade to 8.5.151.
Our Anchors to differnt orgasnisation have no issues as they are on 8.5.140 or below.
The users are authenticating and getting an IP, it's just very very slow. Traceroutes are as should be, there is a 1Gb link between the companys.
Drivers have been updated.
cheers
