LAN Adapter only receives IP 169

Hi,

I am facing a problem whereby this USB LAN adapter isn't able to receive a working IP (it will only get IP 169) when attached to this particular laptop, but works fine when attached to another desktop/laptop. Attaching a different adapter to the laptop while using the same cable, plugging into the same wall port, it receives a working IP. So it is not the router wrong config, or the hardware problem.

I have tried the following:

• disabled, enabled hardware thru netsh interface set interface "ethernet 3" disable
• reset network stack thru netsh int ip reset
• reset winsock thru netsh winsock reset
• plug it into a different USB port
• set it a static IP from Network Adaptor

I am not sure if this might be relevant but I think the problem starts when I had it disabled and plug it out, without having it enabled.


Any taker how to solve this problem, less of resetting windows.


Thank you.

I've seen this happen when the network interface is expecting to find a DHCP server and can't. Do you have anything in the TCP/IP configuration on the failing laptop that would prevent it from using DHCP?

Also look at uninstalling the drivers for that USB Ethernet adapter and letting Windows reinstall them.

Another thing to try:

Go to Start > Settings > Network & Internet > Advanced network settings > Network reset > Reset now
