My PC has USB Wi-Fi adapter, and ad-hoc network is set up. But A500 doesn't see this network as if it's not there. Of course, USB adapter was the only device in this network when I try connecting A500. A laptop has no problem connecting to this network. I've heard that stock Android does not support ad-hoc, but I also heard that knowing the right trick you can get it working on certain tablets. Something for A500 yet?
