DNS's are the same as they have ever been (isp's own) and have never experienced issues. They confirm no isues over the last few days, however now, whilst i am still seeing ppp session up and happy, DNS's seem to disappear (Well they are still there, however things intermittantly fail due to "no dns"...

This is on both a wireless and wired connection.

This is on an .all install with no old backup (re-built from scratch).

Upgrading from 3.3.5.2 to 3.3.7 (*.rst, but uploading an old config file rather than a manual rebuild) breaks the SNMP logging that PRTG relies on.

The SNMP settings in the 2820n web GUI (system maintenance -> management tab) were unchanged; no extra settings or any changes apparent between the firmware upgrades.

Anyone else had a similar issue? PRTG works (i.e. logs throughput) again instantly if I pull back to 3.3.5.2

Have you got DoS defense turned on under the Firewall section? UDP flood defense is the only thing that I can think of that would cause that to be flakey.
