Hi,
We installed few 2011ls with the configurations

port 1 - 5 bridged(bridge-local) with wan ip address on it
port 6-10 are already bridged (ether 6 was removed from bridge-local)
port 6 to 10 using hotspot service or pppoe server
1-5 ports working as wan switch
on port 6 - 10 on all installations we had strange problem every 20 minutes the ethernet used to go down and then up which stops the users on pppoe or hotspot from using the internet. PPPOE clients used to disconnect with logs showing peers lost. On hotspot internet stops working. This happens every 20min or so. Any help would be appreciated

Please contact support and send a supout file from the router.

Couldnt keep my client's network down. 2011L seems to be a buggy product. On 450 its working well.
Returned all 2011l back to vendor
