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!
