Unreliable connection to network behind CPE 210 AP and CPE210 Client
I have two servers in separate buildings which are connected with two
CPE 210 boxes.
My setup is similar to what is described here:
Server 1 -- Switch -- CPE210 AP ------ CPE210 Client -- Server 2
What seems to work:
- If I ping CPE210 AP from Server 1 it works 100 % reliably (so LAN in first building is OK)
- If I ping CPE210 Client from Server 1 it also works 100% (so the wireless link seems to be OK)
- If I ping CPE210 Client from Server 2 it works 100% also (so LAN in second building is OK)
To connectivity between Server 1 and Server 2 is not reliable. When I start all devices,
ping works. But if I try again after a while all packets are lost. Later on the connection might
work again, for some time.
The interesting thing here is that if I clear the arp entry of Server 2 in Server 1 and ping again,
the connection works again. The arp entry was correct, so I suspect that new arp request/response
does something CPE210 boxes which makes traffic flow again.
I thought that this might be a WDS issue. My Client CPE210 has WDS set to "Auto" (I also tried "Enabled"),
but I didn't find any WDS settings in AP.
Any ideas how to fix the problem ?
