There's really no difference in distance from the router I'm usually in my bedroom directly above the router. And doors are not an issue, only my bedroom door separates us, and it's always closed no matter what.

I think I'll wait a bit to contact tech support, I just felt like an idiot, I have a new laptop and was unable to get online with it at all. One day I was online, the next it wouldn't find the signal. Turns out that there's a switch that somehow got flipped that turns the wi-fi capabilities on and off. I had no idea the switch existed, and no idea how it was turned off. Apparently the dog could have done something when she walked over the keyboard to turn it off as well.
