I have had Wifi issues now for a couple months, but it has gotten to the point where Wifi won’t work at all. I noticed a couple of months ago that for some reason my Wifi started disconnecting at my house every few hours. No changes in router, phone settings, new apps, etc. Well, no big deal, I just reconnected. Then it started disconnecting more often. In the last few weeks or so it has gotten to the point where I can’t connect at all to any Wifi system. Not at my house, hotels, work, etc. The basic symptom is that I turn on Wifi, the icon goes to a dull green, then turns back off. Sometimes that takes 30 seconds, other times it just slides back right away. So it doesn’t even turn on at all, never mind connect. This morning I was able to connect to my Wifi for about 40 seconds and download one Playstore update. First time that happened in a few days. Then it disconnected again, Wifi icon was grey. Couldn’t turn Wifi on again. So it is not 100% dead. And given that it has gotten progressively worse I am somewhat ruling out hardware. Also, Bluetooth works perfectly and I believe it is the same hardware connection. Did all the normal troubleshooting Reboot phone Turn off phone, leave it off overnight (I usually do that anyway). Pull Battery. Pull battery while the phone is rebooting. Pull battery while the phone is on. Wipe cache. Reboot router at house. Connect to my other router (Comcast) to see if it works better Forget networks and try to re-connect again. Power up in safe mode, same symptoms. And yes, “Keep Wi_Fi” on during sleep” is set to always. After searching the web for hours seems like there are other users with the same issue. Many of them have wiped the phone (not solved), rooted and renamed some driver files (some say it solved their issues, others did not), downloaded custom ROMs. Went to the Verizon store, they “have never seen that before”. The phone is out of warranty. It is a refurb, about 4 months ago the proximity sensor on my original S4 died. So I exchanged it as the screen would not come back on after a phone call. So, not sure what to do next. Any suggestion from this group? I am running 4.4.2, and I heard that a 4.4.4 update is coming out. Wait for that? Try rooting the phone and download new ROMs (I am very computer literate but have no experience with rooting). Take it apart to see if maybe the antenna connection is lose (that doesn’t really sound like the problem). Give up and get an iPhone? In case I do want to root it, is there a “Root for Dummies” link somewhere? Again, as a former software engineer I am very familiar with computers and embedded systems. Thanks!
