The number 1 Android app for rooted phones out there is undoubtedly Android WiFi Tether, which is a free alternative to all those carrier-bundled WiFi hotspot apps. In fact, it is the primary reason I root every Android phone I own - 2 hours of commute on the train suddenly become extremely productive because of always-on laptop connectivity. I've excitedly written about the app before, especially after it added support for Infrastructure mode and WPA2 on the EVO 4G.
However, after a few months of using the WiFi Tether app, I started experiencing occasional issues maintaining connectivity. The symptoms were:
- the WiFi AP (access point) would suddenly disappear from the list completely
- the connection would drop unexpectedly
- the AP would show up in the list but connectivity with it could not be established
Doesn't sound like fun, does it?
