Home pc lost connection via TPLink cat5

[valleyboy1975]

I have a Windows 8 pc connected Via TPLink cat5.

It has lost hard wired connection yesterday

If I ipconfig it gives

Auto configuration ipv4 169.254.166.250

Subnet 255.255.0.0

Gateway blank

Nothing has changed,if I hover over taskbar on the network icon it says unidentified network .

If I try to ping hub 192.168.1.1

It comes back with reply from 192.168.1.34 destination host unreachable?

Any ideas?

Sorry 8f not enough information

Thank you

Your PC cannot detect any DHCP server on your network (obviously it is in the router, but your PC doesn't know that - it needs to broadcast out to find a server) and the 169.254 address has been allocated by Windows using APIPA, which is short for Automatic Private IP Addressing.

This TP-Link product, I assume it is a Power Line Adapter, what model is it & what lights are on it?

I also assume that you have the new TalkTalk Wi-Fi hub (Sagemcom Fast 5364), what is the state of the light on there?

When you ping the hub, you get a response from 192.168.1.34 - what device is that?
