Wow...lots to unwrap there. I should have never challenged your credentialing as a certified Internet Troll specialist.
First, if you're not familiar with broadband signal-strengths, you shouldn't be giving advice.
Second, if you don't know the difference between webmail and an email client, you shouldn't be giving advice.
Third, you got me on "game controllers." I'm not a gamer but I know the difference between a controller and a console. I should have written "console" and if that qualifies me as clueless, so be it.
Fourth...and this was my point that had somehow galactically shot over your head...lots of things other than Windows 10 can have network-connectivity problems. If a Roku and a home security system experience the same symptoms, more than likely it has nothing to do with a Windows update, driver or CCleaner. These other devices are what most subscribers are "whining" about.
Fifth, rolling back a driver is not only common but an essential troubleshooting step, especially with legacy hardware. If you dismiss rollbacks in favor of "let Windows take care of itself," you shouldn't be giving advice.
