Can't connect via wireless

[howard31066]

I use a HP DM4 with 2WIRE 2701HG-B from AT&T. So..yesterday and before, i could still connect to the internet via wireless. But today, i found out i cant. I havent updated anything on my computer or anything. I can still get on by my phone and my family desktop but only my laptop doesn't work. I tried replugging, readding the wireless, rollback driver updates, etc but still doesn't work

help pls x.x

Can the laptop see any networks, if only to prove the wireless chip is turned on and enabled? Which Operating System is running in the laptop?
