I've been having trouble with my fivespot. We bought to replace dial up and are using this on our desktop computer with a USB cord. The unit will work fine for a few days and then suddenly switch to WIFI mode. Once it goes into WIFI mode, it will not work and will not connect to the network. I cannot get it to switch back - and I replaced the first unit and now the second unit is doing the same thing. We've tried unplugging/plugging back in, resetting battery, restarting computer, crossing fingers, nothing is working. When I tried to call support, they sent a replacement USB cord! I don't think the cord is the issue - any ideas are much appreciated!
