I have Verizon DSL service in my home. Sometimes it will get super slow. Around 0.50 Mbps. When that happens all I do is turn off my S9's WIFI and the speed jumps right back to where it's supposed to be. Around 6.0 Mbps. That happens while my phone is not in use and is just sitting on the table. This has happened quite a few times. Anyone know why this happens?
The biggest WIFI usage is Cloud. That is 4.83 GB. The next is Google play store at 1.13. All the rest are between 0.01 and 0.08 which seems pretty small. That's for a month long time period also. I have turned off Allow background data usage for those but it doesn't seem to make a difference.
