Flaky Wi-Fi on an Android tablet We have been experiencing an odd issue with tablets that we sell, and our vendor is being no help, so we are forced to take matters into our own hands – but so far we've been unsuccessful.

Specs:


OS: Android 5.1
Wi-Fi: Ampak AP6255 onboard Wi-Fi module with a single band antenna.


Issue:

The device will see networks and confirm if the correct/incorrect credentials were entered in, but will almost always never connect. If the device does connect, it will not stay connected. We've swapped multiple antennas out, but the issue still occurs. On a Wi-Fi analyzer, the signal consistently dips. The only way we can stay connected to a network is to connect to a 5 GHz signal, which is very inconvenient.
Check your environment. 2.4GHz is almost always saturated which causes interference and is very sensitive to certain signals such as Microwaves, Cordless phones, certain wireless fire alarms etc...  The best thing you can do is purchase (if you don't already have one) a Metageek Chanalyzer: http://www.metageek.com/products/wi-spy/?utm_expid=190328-202.Egk2FYNZQd6ZdJAUVdEvVA.0&amp;utm_referrer=http%3A%2F%2Fwww.metageek.com%2F.
This will definitely show you visually the state of your 2.4GHz environment.  Since 2.4GHz only has three non-overlapping channels (1, 6, 11) you may be out of luck.  5GHz may be your only solution because it has 23+ channels you can choose from.  The air quality in the 5GHz band is pretty clean.
