I cannot see that it will be IPV6. I am still getting ''network cable is unplugged' then it shows 'reconnected' and also 'limited connectivity', sometimes I can access the internet/emails sometimes not.
All the checks I have run on the system come up clean, so any ideas? Right now the RJ45 shows 'dead' and the wifi is good. Shortly I will need to swap again, and it may or may not work. Reboots seem to fix temporarily.
