DNS is not working on my PC but fine for other devices

Sep 29, 2017 4:44PM PDT

I finished setting up my new router yesterday (got rid of the HH and I’m now running and EDgeRouterX and UAP lite though a Modem (vigor 120). Everything was working fine for 24hrs and then when I boot up my PC I could not access the internet (I could still access the ERX’s web interface however and access the internet’s on other devices). I have narrowed it down to a DNS problem, so please ask for what ever info you need, I just MUST get this sorted.

Thanks guys!

Clarification Request
You claim it's a DNS issue

But I worry you didn't try another DNS on the PC in question. Try next on that PC.

Also, some security suites block this when they expire. I have no kind words on that and call it thuggish behavior.

Possible Fix
Oct 2, 2017 9:11AM PDT

Given that your new home router and your Vigor 120 modem is providing Internet to your other devices and only your computer lost connectivity after 24 hours, I would consider this to be a local issue between your computer and the modem. There are a number of things you should do to try to regain connectivity to the Internet on your computer.

The modem and router need to power cycled. This involves unplugging and replugging the power adapter from the modem and the router for 30 seconds each at the same time. It should take up to 5 minutes for all of the lights normally lit to come back on.

Next, verify the Internet adapter(Ethernet or Wireless) is set to automatically get the IP address of your router (DHCP) or the IP address of your router is set along with a DNS IP address.

You should also refresh the DNS history or cache on your computer, too.
* Log into the Administrator account.
* Open up the command prompt interface by typing,:
ipconfig /flushdns
ipconfig /release
ipconfig /renew
This will clear the DNS cache and refresh the adapter that connects to your router.

Seems to be an issue with the configuation on your PC

Since its working with other PCs there is no issue with DNS or the internet
Is the DNS configuration on your PC set to “obtain DNS Server address automatically”?
