A small How-To how it's done for me. Iron — wifi is distributed through cheap slavushka with chip Realtek 8185, which virtual adapters if supports, I could not do, so connect via ad-hoc.
1. As Android adhoc is not friendly, had to pump pacany wpa-supplicant here
. Set as normal mod via ROM Manager — throw in the root, reboot into recovery and install.
2. Raise ad-hoc in Windows: control Panel — network and sharing Center and sharing — Manage wireless networks — Add button "to create a network the computer-computer" — next — enter any network name, encryption and password is a good choice.
