Apple - Share iPhone WIFI with computer over USB?
Sorry, but it's not possible to do this without jail breaking. The "Personal Hotspot" function on an iPhone only allows for sharing the 3G connection, not the wifi connection, so you can't use it as a wifi adapter. It's feasible that Apple could add this functionality, but it's a fairly niche case, so I wouldn't count on it.
More immediately, if you have a laptop with wifi available, you could use Internet Sharing (OS X)/Internet Connection Sharing (Windows) and an ethernet cable to get connectivity to your desktop. Or if you've got a Staples or something similar nearby, they usually have USB wifi adapters for $30 or less.
Of course this is possible:
- Your iOS device must be joined to wifi connection
- Your iOS device must be jailbroken
- Your PC must have iTunes on it
- Install MyWi 5.0 over Cydia (Cydia will be installed on your iOS device after you jailbreak it)
- Choose USB tethering in USB tab
- Set MyWi USB to ON
- Go to Advanced USB
- Set USB Bridhe to "Bridged to WiFi" so you don't get online via 3G
- Enjoy your wireless internet connection
which iPhone and iOS versions are you using? you will also need to check that your carrier allows a personal hotspot.
if you are able to turn on a personal hotspot on your phone, just connect the phone to the PC with a USB and enter the Wi-Fi password after finiding teh phone in the network settings.
You could also just get a WiFi USB which would pick up the WiFi from the router.
