Computer Can't Even Get Information From Router Through WPS

I am having problems trying to connect to my wi-fi. I first noticed that I had problems connecting to some types of unsecured wi-fi connections when I was "borrowing" from my neighbour while I waited for telus to install my internet. My two roommates would have no problem surfing but my computer was unable to get any connection to the internet (i could see the connections but never load a page)

Once telus came and installed the internet I was able to get a "fair" connection to the router and surf with decent speeds. About a week after I first started using the internet, my computer started being unable to connect the router. It seems that everything is getting worse and worse. It started by me having to restart the adapter a couple of times to make it work, to me having to delete the network profile and then redo it, to me only being able to connect by using the WPS.

And now my computer can't even get the information from the router through WPS! I would start to point the finger at telus, but every one of my roommates has no problems connecting to the internet, and it's not a range issue (i'm typing this up with my laptop while sitting beside my desktop).
