i've been sharing a house with a mate for 18 months, the router has been plugged into one of his powerline adapters since he moved in, i've got one of mine in my room connected to a hub then my android box, ps4 & pc wired to the hub, everything has worked great, he's just got a job down south and has moved out this weekend so i've plugged my other powerline adapter in downstairs, the connection works cos my android box & ps4 are fine but i can't get a wired connection on pc anymore, basically says unidentified network and the troubleshooter says "ethernet doesn't have valid ip configuration"
in ipconfig there is no default gateway, the ip address is 169.254.247.234 & the dns addresses look fucked up, something like fec0:0:0 so guessing it's a dhcp issue?
i've googled the problem and have tried all the solutions i've found but can't fix it, any ideas?
