I have 4 M5 decos , all setup in router mode and they're cabled through wired connections in my house. The main deco is connected to a Virgin Media Hub. I have a network switch conencted to my main deco through which all wired devices and sockets in the house connect.

Today I decided to change the switch to one with more ports. While the fi-fi connection to the main deco still works fine, any device with a cabled connection is active on teh netowrk, but is not abel to access the internet - see the screenshot from my mac.

I haven't changed anything else on my network at all and I have even re-instated the orignal network swtich and rebooted everything etc. but the problem persists.

I have a lot of wirde devices and this is causing me a headache. Please help!
