No internet via ethernet

mattyb93 · 19 Feb 2021

Hello

I'm having some trouble with my connection over ethernet. Wireless works fine and the same ethernet cable works on my laptop. The problem is my ethernet on my PC. Firstly I used the windows troubleshooter and got the error "No valid IP". I checked my ip using ipconfig and it was "169.254" range. I saw online that's it's a ipv6 address. So I disabled IPv6 and restated PC still with no luck. I tried the flushdns, releasedns and renew dns. Renew dns came back with something along the lines of 'can't connect to DNS server'. I've even tried setting up a static IP. On my router webpage it says the statip ip device is connected but still not getting any internet on the PC. Windows troubleshooter now says there's no issues but still no internet. I'm on Win10. Got the PC in December and always used wireless. Ethernet has never worked.

Any suggestions will be a big help.

Thanks

Since the Ethernet connection has never worked I'd be looking in the BIOS for the setting that Enables or Disables the onboard port. If okay look in Device Management in Windows for the same. When those checks don't produce results I will boot a Linux LiveDVD or LiveUSB to test the hardware. Also, when you first set the computer up was it connected by Ethernet cable to the Router for the updating and activation [all I've set up required it at some point in the process]?

Open a cmd prompt type

ipconfig /all

post results this will show us whats going on

So I've attached a screenshot of the ipconfig /all results. I've also attached the screenshot of the ipconfig /renew. I've looked in the BIOS and everything that should be enabled is enabled. On initial setup I did everything over wi-fi.

Thanks

That 169.254.4.104 is a Microsoft APIPA address (Automatic Private IP addressing). Generally you don't see this unless the NIC can't find the DHCP server, which your attempt to renew the DHCP lease confirms ("unable to contact..."). Does wi-fi work, but no wired Ethernet? If so, please show us ipconfig when that connection is working. Thanks!
This may take a while, but we'll help you get this sorted.

Thanks for all your replies. Looks like it's now working. I forgot to mention I'm using a powerline adapter for ethernet as my router is downstairs. I didn't think it would be an issue as it's always worked for all of my devices and never had any problems but I had to rule out the possibility. Took the PC downstairs and connected directly into router. Bingo it's worked! I then connected via the powerline adapter and ethernet cable and it's still working. Maybe there were conflicts or I needed to connect directly to router on initial setup, I'm not really sure, but seems to be working now through the powerline adapter when it didn't before. So weird. Maybe someone may know the reason why? After a few restarts it's still connected, hopefully for the foreseeable future.

Thanks again

Most powerline adapters need to be synced in order to work moving could break the sync. Once connected to the router you would get an ip lease for x time which may run out and it may stop. note all the ipconfig /all settings and if it doesnt work set a fixed ip with those settings

My personal laptop and work laptop both connect through the power line adapter, so too does my Xbox so that’s why I initially thought the adapter wouldn’t be the problem. If they’re leasing the ip successfully for a few years now why couldn’t my new pc do it. I tried static ip before and it didn’t work but I’ll write this one down just in case thanks.
