Hello @thing324,
I had a similar problem and was finally able to resolve it with the help of this forum. I’m new to the phone world [since I had no trust in the “normie” phones (phrase coined by Rob Braxman)], so I’m a total beginner in how to use one. I asked for a simple explanation to fix the no wifi issue and this is how I was able achieve that. Please see the following thread, starting with post #40 from @dpourkesali. I hope it helps you, too.
[ . . . Ummm, I’m not quite sure how this is done, how to link that post onto this post. So is it OK if I just copy and paste the URL of that conversation here? Or is there a simpler way? Sorry, I’m new to forum posting, too. If not, maybe you can search for the title of that post as seen in the link?]
