RV220W Connection Drops Intermittently

I installed the RV220W Router in my office about 2 weeks ago and everything works perfectly for 3-4 days but then my connection drops out and the router must be restarted to restore connectivity.  When I say the connection drops basically the internet connection drops out and my network connections drop shortly thereafter.  Usually the wireless connections lose connectivity followed within a few minutes by the wired connections.

Is there something in my firewall settings that could cause this issue?  I have checked with my ISP to verify there are no problems on their end.

Hi Craig,

Could be..a firewall issue. 

In earlier firmware i think the default behaviour of how it managed udp flooding was very tight.  I was a response from a Small Business Support Center technician, in a similar post that suggested;

"Have you tried disabling "Block UDP Flood" under the Firewall Settings and under ICSA Settings disabling "Block Fragmeted Packets?"

I actually turned off the "Block UDP Flood" and "Block Fragmented Packets" firewall settings yesterday afternoon.  I'll report back on the result.  Since the network is usually stable for 3-4 days before I have an issue it might take a week or so until I am convinced the issue is resolved.

My connection just dropped again today.  So apparently the firewall settings are not the culprit.  I am planning to replace this router with a suitable replacement.  It shouldn't be this much trouble to get my router stable.

Craig,

Do you have the block denial of service attacks?

If so, thats probably what is happening.  If you log into the router when the wan shuts down and see if there are logs showing an attack.

These routers are designed with that function and if it detects an attack it will shut down the wan port to protect the network.

You can turn off this function and risk someone getting into the network.

I share a similar problem: Occasionally (5%), webpages are not reachable.

In addition to "Block UDP flood" and "Block Fragmented Packets" I disabled also "Block TCP flood". Since then I never had troubles to reach webpages.

After disabling every firewall setting on the router I finally abandoned ship and went for a new router model.  Unfortunately when you are a small business owner you don't necessarily have endless hours to play around with router settings to create a stable company network.  I love the performance of the RV220W but I won't recommend it to anyone if it doesn't work out of the box as advertised.  Network down time = lost money.

Hi Dave,

I have a 1.0.3.5 firmware and I keep losing my wireless, I didn't have this issue with the shipping firmware, should I downgrade or is there a known configuration that works best for the wireless?
