I am not allowed to have comcast come in and install a bunch of stuff. I have wifi though. Any ways I can get live tv and a decent amount of channels? I'm willing to spend money? I tried an antenna and that didn't work at all.

You can buy a set top digital box which you can connect to the internet to get channels - just go into any electrical store.

If you have a computer then you can get all the channels you want online.
