Last week I downloaded Windows 10. Since then my Internet connection has slowed from the 30 mbps I pay for down to 1 mbps. I have made sure all my drivers are up to date, updated and performed a full scan with my anti-spyware/anti-malware software, and performed all the disconnections of sharing that I can think of. Is there some way to restore my Internet speed? This is regarding Wi-fi speed, and all other devices in our home on Wi-fi (which are still on Windows 8) are performing at full Internet speed.

Some problems occurs when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;

  • Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
