well, I no longer have the toshiba. The POS fried its motherboard under normal usage. I suspect it was just a really unhappy laptop. In any case, I was eventually able to get the wireless working (before the motherboard incident of course). What did it take?
A clean re-install of seven. Full hard-drive wipe and custom install. After the fresh install, it found all of its drivers automatically. I have no explanation for why it works, it just did. Prior, I tried everything - older drivers, new drivers, windows update - EVERYTHING. Nothing worked until re-installation.
My suggestion: wipe it. re-install seven, should work perfectly. Just make sure to back up all of your important data first
Best of luck to you
