ok, that is something to work with. your rom is not a shipped one, and from the version number, i can't tell, who cooked it and how old it is. however, it might be a common bug of that rom that wi-fi doesn't work properly. also, your radio is fairly uncommon, most people these days use the latest radio 1.17.29, which can be found on the forum. remember to perform a hard reset after flashing another rom or radio rom. in general, one can assume, that, once you flashed a shipped rom and the latest radio, the software on the phone is as it should be, and if wi-fi doesn't work then, it might actually be physically broken.
