I have a connection running from a router through a powerline adapter to an old router (being used as a network switch) to two computers. This was working fine until the other day where I was receiving no network connection.

 

In trying to fix the issue with my limited knowledge it's possible I've made it worse. I was messing around with the IPv4 settings on the ethernet connection (trying to set my own IP address, which I've since reset to "obtain automatically"). I noticed the error described in the title and have been unable to fix it.

 

I currently have the powerline adaptor running directly to one of the computers (I've tried this with both of them).

 

When I run

ipconfig /release

ipconfig / renew

I get "An error occurred while renewing interface Ethernet : unable to contact your DHCP server. Request has timed out."

 

My ipconfig /all results:

I've gathered that there are several telling issues in the ethernet section including the 169.254.xxx.xxx autoconfiguration ipv4 address.

I've tried following a number of the fixes in this post (https://www.bleepingcomputer.com/forums/t/542591/no-network-connection-autoconfiguration-ipv4-address-169254xxxxxx/) but to no avail.

 

Any help would be greatly appreciated because, if it wasn't already apparent, I'm in way over my head.

Can other devices connect via the powerline setup?

I would suggest a direct connect to the main router wired to test if what is in between is the problem.

So I've just turned on my computer to find that for no apparent reason the powerline - computer connection is working again and correctly assigning the IPv4. Gonna try reconnecting the switch and seeing if it still works.

Though I can see you've fixed this issue, if it happens again I would recommend setting a static IP like you tried..

Your IP address should be out of your DHCP range on a static address (not 100% neccessary but avoids many issues)

So lets say your dhcp is set to 192.168.0.10 - 192.168.0.150, set your static at 192.168.0.151 or higher than 150.

Subnet 255.255.255.0

Gateway 192.168.0.1 (your router address)

I would use the DNS from google- 8.8.8.8 , alt dns 8.8.4.4

 

Hope you won't need this though!

So the internet worked fine over the weekend but returned to the previous issue as of Monday. I occassionally have wifi working, but not often. This happened to both computers.

I set up the static ipv4 but still no connection.

Seems unlikely since the wifi on the device is playing up too.

The computer can connect to a hotspot from my mobile jist fine, other devices connected to the router operate fine. I feel like it's some OS bug that was triggered by the old router/switch. I'm stumped as to how to fix it.

There's no chance you may have blocked it in the router settings is there? It's a bit odd that it's only that router it isnt working with!
do you have a second router you could test with that machine / take that machine to another router?

Unless I also blocked the router I'm using as a switch it seems unlikely to me, especially considering it occassionally works fine.
