Hi, I'm being told by my pc that the ethernet cable isn't connected. I've done all the usual stuff i.e. checked the cable, tried it in different ports, tried a different cable, switched everything off and left it, all to no avail. I have 4 ports on my router and I know they're ok because I use one to connect a powerline adapter and I've tried that in the different ports. Whichever port I plug the ethernet cable into the LED doesn't stay constant whereas the powerline one does. I've also tried changing the adapter's Duplex settings and for a while thought I'd solved it as the LED light stayed constant and the pc was thinking about it, but then decided I was connected to an unknown network and wouldn't play ball. Any ideas as to what else I could try pleeese?
