Hi,

Running a Draytek 2926 in an office and certain sites (mortgage broker sites mainly) are not loading on any machine connected via ethernet, same machines with a WiFi dongle plugged in work without a problem. There's no difference between wifi and lan settings on the router so this is driving me mad!

Any advice would be great, thanks.

Okay , things to try assuming some sites are okay on ethernet ;

Reboot router

Try different dns servers

Check the MTU setting (max 1492 if using a PPOE connection )

Flush the dns cache on the computers.

If they are Windows PC's try resetting the network on one device to see if that helps.

The one you are probably wanting to avoid, reflash the firmware and / or reset the router .
