Hmm yea bro, the wireless router you have isnt like the best, ,but is should be ok.
i thought it would be some old like 1980's thing lol
I would look into getting a wireless card for your pc.

the problem with the usb adapters, is (as you have probably noticed) that they get hot, and just like pc's if it gets hot it works harder than it has to and lessens your performance.
but yea. i have the router u picked in the middle. and it was easy to set up and works great. though., my apartment is kinda small and am like kk only 6 feet away from it lol
