I had an issue many months back which have since stayed resolved. Whatever changes I did or firmware came through since then has done the job. It very rarely happens to me anymore (public library). Maybe once every six weeks and it doesn't happen at home anymore.
In light of that, I would suggest we start trying to send a basic set of data over to help each diagnose the issue. It can't hurt, right?
I will start the initial list:
Retail: Samsung S8+
Hardware version: REV1.0
Network Mode: Global
Show WiFi Popup - ON
Smart Network Switch - OFF
Wi-Fi notifications - ON
HotSpot - OFF
Keep Wi-Fi on during Sleep - Always
Wi-Fi Control History - Removed all
Wireless area notes:
I actively remove wireless networks that require constant sign in. For instance, in my area, Xfinity/Comcast has lots of hotspots all over the place. In fact, with their equipment every home automatically advertises an Xfinity Hotspot. You have to proactively go to your online account to disable it. So if I keep the connection saved it will constantly try to connect to one as I roam around the area. Since WiFi is preferred over Celluar, the phone can be aggressive trying to connect to networks it has connected to previously. Also, I do not use WPS.
Router: Asus RT-AC68U
Firmware Version: 188.8.131.52.382.18547
Wireless Band: 2.4Ghz and 5Ghz enabled
WPS: No WPS
SSID: Both advertised and non-advertised SSIDs
IP Address: Auto-assigned
Samsung Switch - Uninstalled
Samsung + - Uninstalled
Side Sync - Uninstalled
My S8 has been fairly stable since going to a static IP. However, my old S6 just received an OTA from Verizon, and you guessed it, now it's infected too. It's interesting that the static IP workaround has no effect on the S6 problem but using the old Guest Network workaround from early on in this thread is working. I assume that at some point, I will have to switch workarounds for the S6 like I had to do on the S8. The saga continues...
Funny that this forum says "resolved" b/c it's definitely still happening!!!
So I have a Samsung S6. There was a work around mentioned about the guest network... how can i find that?
The first reference to the "Guest" workaround was by Sorven in this thread on 7/30/2017. Just realize that at some point after an OTA update, it will stop working and then you have to switch to the "Static" IP workaround, which to this day, is still working quite well for me.
