Android 2.2 Wifi > Bluetooth : bridge & tether DUN
This isn’t a common situation, but without root it seems you cannot share or rebroadcast a given SSID using your Android’s wireless chipset, however, using PdaNet, you can share a wifi signal via bluetooth with a laptop or another device running PdaNet.
So there, I hope that’s the answer you are gøøgling right now.
Once paired successfully over bluetooth, on the client laptop you’ll need to enter “123” as the dial up phone number in the DUN settings.
You are welcome.
