Disable WMM QOS to Stabilize Android 7.0 WiFi Connection

When I upgraded my smart phones recently to Android 7.0 I started to experience WiFi issues. The phones would constantly disconnect and then try to reconnect to the network.  The other devices on my network seemed fine which indicated the problem likely was with the Android 7.0 build considering the phones were fine before the 7.0 upgrade.

After a few days of looking online and adjusting settings on the phones I was quickly realizing it was time for Wire Shark. After grabbing some packet captures I started looking through the TCP stream and was able to trace the issue.

After reviewing the WMM protocol logic and looking at the TCP stream it seems that Android 7.0 doesn’t handle the power save station (STA) triggers correctly which causes a reset.

I disabled WMM on the router and the problem was solved. In theory disabling WMM should slow traffic but not enough to be noticed.

Using Google’s Android Phone app to beat spam calls

The Google Phone app can instantly pull up info on any unknown calls coming into your line — and in a particularly cool twist, it can also warn you if the number is known for spammy activity.

Also with the Google Phone app and Android 7.0 or higher, you can block specific numbers with a couple quick taps — and your list of banned digits will always stay synced with your Google account and thus will automatically be present on any other phones you use in the future.
