Thanks for posting this, doc. I want to report that although my WiFiRanger was recently updated to the latest firmware, this bug-fix has made a big difference. It downloaded, installed and re-booted unattended, and has locked on to an otherwise weak open AP. I is providing us with a great signal, significanltly more useable than without. (Actually, my wife's iPad kept dropping the wifi until I had her log in on the WFRanger.
I also remember numerous times when it used to drop and re-boot, or present a few other of the bugs, no fixed.
So THANKS to the techs at WiFIRanger, and to doc. If anyone here is thinking about getting something to increase their wifi range, this is the hot ticket.
