wifi dropping

put the WiFi off then on

Im sure they have tried that. i had the same problem with my first one s7edge Tmobile. I got the internation sm935fd andhavent hsd isdue since but thebest fix i hsd was turn smart switch off (wi fi setttings) than in locations settings turn off allow wifi scanning and blutooth scanning. i also turned agressive switch on in developer options if unure how todo that go to about phone in settings find buid number and tap it 7 times. It didnt solve the problem nut made it less frequent and didnt dtop connection when i lost wifi. i think the problem is in the router or was for me anyway. i had a new netgear but i noticed at times when my wifi dropped it wasnt just on my phone. Something with the internet protocal but thats just a guess. i reseached and messed around for along time trying to solve the issue its part of yhe reason i got a differnt phone.
