Problem with connection to home Wi-Fi - how to debug?
My Android tablet also stopped connecting to my home wireless and reports connection out of range even when sitting in the same room as my access point (AP). I've looked everywhere for a solution doing everything from restarting my AP and tablet, changing the PW and even security mode (WEP, WPK, etc) with no success. My AP is an old router set to AP mode and uses a single broadcast channel. I went in and reset the channle from 13 to 11 and VOILA! Instant connection with my tablet.
