Don't I feel silly. After uninstalling the update, the internet was still slow, so for kicks, I unplugged the ethernet cable and plugged it back in. It's running fine. Speed's back up and I'm all good. Thanks for all your help. Who knew it would be the simplest fix that did it!
Good day!   I have an Inspiron 3650 that is almost 5 years old. I recently downloaded a Dell update, and now my internet speed has dropped significantly, where I can't watch videos and scrolling comes in blocks. Is there a way to uninstall the particular update or a fix for it? Hoping someone's had similar experience. Thanks! Gary . . .
