Hardware :: Connection To Internet - Acts Like Searching For Wireless Router And Can't Find It

Recently I have been having issues loading internet content. When I try to load almost any website, my internet browser acts like it is searching for my wireless router and can't find it. However, when I use my PSP to connect to the internet from the same spot, it works perfectly fine. The PSP usually says there is a 70% connection, which is better than it has ever been. My router and laptop are on the same floor only a room away.

I have other people in my house that share the router: 6 computers; 4 are laptops that are used more often than the 2 desktops, 4 iPod Touches; 2 of which are never used. I had everyone turn off Bluetooth on all devices since none of us use that feature and that didn't help all.

I honestly don't know what the problem is, but if I had to make a guess, it would be all of the things that our devices can connect to with AirPort. There is Motorola, 2WIRE017, 2WIRE160, 2WIRE417, 2WIRE730, MartinWirelessRouter, NorzWireless, NETGEAR, schooly, and stackdaddy. I think all of these wireless connections are disrupting one another, which is what I thought was causing the problem. The only one I ever care to connect to is Motorola, so is there a way to prevent my computer from even recognizing anything else?
