Unable to connect to Google (www.google.com) after router change.

I recently changed to a 4G network based router because of poor internet speeds in the area.

Since changing I have noticed that when using my TP-Link AC1900 network adapter, I can no longer access www.google.com specifically. I can still access the site on Edge (using the adapter) and when I change from the adapter to the primary wifi card in the laptop, Google works again in Firefox.

Due to the things I've tried (listed below) I've come to believe that it must be some strange interaction between the adapter, firefox, and the network.

I've tried the following: - Deleting all cookies and data - Reset all preferences in Firefox - Disabling and re-enabling addons - Fresh install of Windows (including Firefox) - Reinstalling TP-Link Drivers - Changing DNS to Googles servers - Firefox network settings (no-proxy etc...) - Checking the firewall settings on Windows (disabling, allowing firefox.exe, etc...) - Restarting the router - Changed some of the DNS settings in about:config, but resetting after to be sure

I've looked around for pretty much every similar post, some people saying the issue resolved itself, but any solutions I've found so far haven't worked. This is beginning to become a bit frustrating as I mainly use Google to search :( Hopefully someone who's had a smilar issue can help me resolve it, thanks!

Just to clarify, I get this response when trying to connect:

Hmm. We’re having trouble finding that site.

We can’t connect to the server at www.google.com.

If you entered the right address, you can: 

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)


Is there any way to acess debug info from this point to see what exactly happened, some kind of log?

So are you using the 4g device to get to the internet? I sounds like it's not able to handle the bandwidth. I would check with that 4G provider and see what is happening. How are you setup with the 4G device?

You can check this in the Network Monitor and possibly use the DNS Lookup tool on the about:networking page.

Are you using a proxy or VPN?

You can check the connection settings.

  • Settings -> General -> Network: Connection -> Settings

If you do not need to use a proxy to connect to internet, select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.

See "Firefox connection settings":
