Hi there,
we have a Accespoint with three 120 degrees sector antennas. The AP is running 4.13 ... three of four clients (all connected to the same antenna) run 4.13 also, only one client runs old 3.20
The AP is using nstreme (exact size) and 5Ghz turbo Mode. All sectors are using different frequencies (5800, 5290 and 5210)
Now i have the issue, that the 4.13 clients are disconnected within some days. All show "lost connection, not polled for too long" .. the only client that stays up is the one with 3.20 running .. all clients have nearly the same link quality (ccq is 100%) all clients have LOS .. HW retries is set to 7 (default)
I have no idea what's causing that.
Any hints or ideas?
Thanks and regards,
Joerg
