Okay, just wondering if this can be done. I have a mytouch 3g fender. My wifi router sits down in the basement. and i have a computer in the attic, which the signal sadly not reach. Thus I was wondering if i could connect my phone to the wifi, say in the middle of the house. then tether that connection from my phone to the attic computer? I tried barnacle wifi, but that only works with the data network- 3g. But i want use a wifi to wifi tether. no service provider 3g to wifi. is this possible?
