Hey guys, just put together an old computer for my brother to do homework and play some flash games on. It is running ubuntu and with the processor overclocked, it's not too shabby for a ten year old computer. Now, my only problem is, there is no onboard wifi and the computer is going to be located 2 floors down from the router in the basement. My question is quite simple; I am looking for a Wireless N receiver, but I do not know if I would get a better connection with a PCI connection, or USB connection. Are there any pros, or cons to either? I have 3PCI slots available and about 5 USB slots available, so neither is an issue, just trying to get it up and running with a strong steady connection, as well as keep it budgeted, let's say $10-30. Thanks in advance
