It sounds great, but I tried everything, and it just will not work for me on my Sprint Nexus S 4G. Anyone else got it to work?
1. On some models if you run into WiFi problem after using the Hotspot, simply reboot your phone to clear the issue.
2. For some Samsung phones if your computer is not able to get an IP address, try to turn on WiFi on the phone first and make sure it does not connect to any WiFi network, then turn on FoxFi.
3. FoxFi is tested on non-rooted phones. If your phone has a rooted ROM it may or may not work.
4. When WiFi hotspot is activated you may also see a hotspot notification of the built-in WiFi hotspot feature. Please ignore it. As long as you do not sign up for a tether plan you won't be charged.
While this is the Bionic forums, still, here are some tips from the market listing:
Since you have a Samsung Nexus S, look particularly at number 2 and number 3 (if you rooted the phone.)
The market listing suggests using Bluetooth mode if WiFi mode does not work with your phone.
