PDANet/FoxFi Trouble Shooting Tips:
If FoxFi ever works for you before and now giving you problem, the first thing you should try is to reboot your phone and rename the hotspot before activating FoxFi.
After updating PdaNet+, if computer shows a red "x" on hotspot or you get error "Settings saved on this computer for the network do not match", just rename the hotspot on the phone side and activate FoxFi again to solve this issue. This is because the new version of FoxFi uses WPA2 instead of WPA and the computer side has a bad entry cached.
If you have a Samsung phone, occasionally your computer may fail to get an IP address (shows Limited Connectivity), if that happens try to turn on WiFi on the phone first and make sure it is disconnected from any existing WiFi network/router. Then turn on FoxFi and see if it fixes the issue.
WiFi mode is tested on non-rooted phones. If your phone has a rooted ROM it may or may not work.
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.
If you enter or change the hotspot password, make sure you rename the hotspot also before activating.
Sometimes Windows need a "repair" on the WiFi menu to get a correct IP address.
If your carrier blocks your tether usage in WiFi mode, try to use USB mode instead in PdaNet+ and set Hide Tether Usage to Level I.
