=== Android device connection problems ===

Certain [[wikipedia:Android (operating system)|Android]] mobile devices ([[wikipedia:Mobile phone|mobile phones]], [[wikipedia:Tablet computer|tablets]]) may connect to Wi-Fi and work for a time but then "hang" or disconnect. The cause appears to be a bug in certain [[wikipedia:Texas Instruments|TI]] Wi-Fi drivers most commonly used in certain [[wikipedia:Motorola Mobility|Motorola]] products.

The best solution may be to replace the Android device with a completely different device, if possible, that works properly everywhere.

Otherwise, a possible work-around (where you control the wireless access point or wireless router, but not in other places) is to either:
 +
<ol style="list-style-type: lower-alpha;">
 +
<li>disable [[wikipedia:Wireless Multimedia Extensions|WMM or WME (Wireless Multimedia Extensions)]] in the wireless access point or wireless router (not the mobile device), at the expense of WMM/WME functionality; or</li>
 +
<li>replace the wireless access point or wireless router with a completely different device that's more tolerant of mobile device issues.</li>
 +
</ol>
