Since applying 3.3.3 to the 2820n, I've been getting lots (ie at least 2 an hour) of instances where my network connection drops as if the network cable has been unplugged, and re-connected.

I have checked the cable to see if it was loose, in case it was a coincidence, but it's still rock solidly connected.

I have re-flashed back to 3.3.2.1 to see if the issue remains, and will report back later today.

Do you mean the ADSL connection is dropping? If so which modem code did you install and was it different to the one you were using before?

If it says network cable unplugged, that usually means its resetting itself. If you do "sys ver dbg" in the telnet interface it'll tell you if & why its resetting.

No, my PC (and that of all other connected machines) network connection was dropping to a yellow exclamation mark with limited connectivity for about 5 seconds before re-acquiring sync with the 2820.

My apologies, my description wasn't 100% accurate, it wasn't changing my network connection to the red X of unplugged, but to the yellow ! of limited connection.

Either way, I'm still on 3.3.2.1 and it's been solid since re-flashing, so I'll wait for 3.3.3.1 or 3.3.4
