I experienced slow internet browsing after Win 10 upgraded to 1607 with non-MS browsers such as Chrome, Firefox and Opera (chromium) and I was surprised to find that MS Edge didn’t have any problems browsing. I found that weird, so I frantically looked around the web to see if anyone was experiencing the same. Thankfully, I’ve found this article from MS support and applied it. It was a relief; all three browsers were now functioning well.
But I’ve encountered it again lately. Chrome, Firefox and Opera browsers were again experiencing very slow page loading, very slow browsing, timing out or not connecting to the internet. MS Edge again had no problems. *sigh* Was it a result of a windows update, I really don’t know. But then, I proceeded to reapply the previous solution, this time though they had no effect. I didn’t understand why it didn’t work this time. So, it was back to searching the web. It took me a very long while until I came across this article from Make Tech Easier. Please refer to the article for the instructions and settings.
I applied Increase DNS Cache, Retrieve Your Bandwidth, and Switch off Auto Tuning settings to the registry. It worked! Thanks to that article Firefox, Chrome, and Opera are now working as they should be. Hurrah, they’re fixed! My only question is did a Windows update change/remove something in the registry?
Run the Network Troubleshooter, if it doesn’t solve the problem, do the next step.
Run the following from the Command prompt as an administrator (please refer to the article for the commands and explanation)
- Reset the TCP/IP stack -> Type netsh winsock reset and press Enter. Type netsh int ip reset and press Enter.
- Release the IP address -> Type ipconfig /release and press Enter.
- Renew the IP address -> Type ipconfig /renew and press Enter.
- Flush and reset the DNS client resolver cache -> Type ipconfig /flushdns and press Enter.
then also apply the Increase DNS Cache, Retrieve Your Bandwidth, and Switch off Auto Tuning settings for good measure and then Reboot Windows. Firefox, Chrome, Opera and your internet should be back to normal.
They helped me a lot. I hope this helps anyone experiencing slow internet browsing, not connecting, and timing out on Firefox, Chrome and Opera browsers.
