I got random wifi drop (disconnect + connect) with my S7 in my home network, sometimes 1 time in 2hrs, sometimes 4-5 times per hour. This is annoying since the S7 vibrate when losing wifi, and make sound when conecting. I tried every solution availables on xda, android central, and didn't find a solution that fix my problem.
In my case, the issue is on the 2.4 band and also on the 5.0 band. My router is a Dlink DIR-868L, updated to the latest firmware. All my other devices, including Galaxy Tab S2 have no issues.
I tried:
- turning off Bluetooth (also the scanning in location)
- changing channel on router
- turn off smart switch
- factory reset
- ...
In last resort, i plugged in my old router (DIR-628) on the 2.4 band and got no issue, so i looked to find wich parameter on my DIR-868L is the curlpit.
So, i found that changing the channel width from (Auto 20/40) to 20 solve my issue, no drop since the last 15 hours.
Little tip: I used and app called "WiFi Logs" to monitor my wifi connection.
Hope Samsung will fix the firmware soon!
