Yes thanks for that. I've had a look before. However, it doesn't resolve the problem that the devices are not accessible through the browser or ping test.
And one can only conclude it's got to do with this Netgear variant because it all worked on the Thompson before. Nothing has changed in the devices.
I'm clueless, now pursuing the way back to O2 or a different provider where I can simply choose my router and basta.
Or does any one have a good recommendation on which device this would-be cable router could be replaced with (would need to include the ability to adjust the MAC address)?
Might be worth asking for info in the Virgin Media (cable) forum.
Does this help?
