Help WIFI On S3?

[John9999999]

Good evening,

So I had issues with my wifi on my S3 a few weeks ago. Whenever trying to connect to WIFI, the button would be a grey/green for a few seconds then turn back off. I factory reset my phone and started it in safe mode, which fixed the issue. The internet worked perfectly. Then yesterday it started acting up. It is extremely slow and turns off sometimes, but turns back on later on. I tried factory resetting it and booting in safemode, but nothing has worked. Any ideas what I could do to fix it? Thank you

Long shot, but take the back off, get a watch screwdriver and check that all the tiny crosshead screws around the outside are tight - at least not loose. I had an S3 mini where this cured the same problem. Connection to the antenna was affected I think.

That does sound like a hardware issue. Either the antenna or the wifi chip.
