Flaky Wi-Fi on an Android tablet
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.
