@tim_laura You're very welcome. I'm glad it helped. :) I had a similar issue a while back and a person on here helped me with that exact settings change, so it's kind of paying it forward.

I have the 3521 model from about five or six years ago, but it's very similar to yours, as is the WiFi network adapter it uses. And though I most often use the desktop I'm not now, I do use the laptop occasionally, which still works perfectly.
