Sorry I think the answer to that question was already mentioned in the first post, my bad.
So lets try troubleshooting this one by one.
Firstly let rule out the obvious even if it looks stupid. Make sure you have a working cable. Then make sure the cables are connected at both end FIRMLY. sometime a loose connection could be the root cause. if the Ethernet is a PCIE adapter that slots in to the computer motherboard, then check to see if its FIRMLY fitted to the slot. If this resolves the issue, good .... else follow the next step
Secondly lets rule out driver issue. Go to device manager and right click on each adapter and uninstall it even the ones with exclamation. Make sure while you do this you only uninstall and NOT DELETE the drivers. reboot and check to see of this resolves the issue. Post a screenshot of the Network adapters after the reboot.
let me know so we can advice you the next course of action
I can confirm the connection is secure. The cable is new, about 5 months old. I also tried with another cable that was bought at the same time for my TV and both were checked using ipconfig with the same results.
I will uninstall all drivers. When I right clicked it, I did not see any way to delete, just uninstall, so no need to worry there. Won't I need to reinstall them get back on the internet? If you look at the first screenshot I posted, you can see 4 adapters that had yellow exclamation marks which are no longer there. Since then, I have had to restore to an earlier point many times to get back on the internet via WIFI but this is the first I've seen where all 4 have disappeared.
