Hi guys. I have a relatively old desktop computer (i.e. Intel Core™2 Duo Processor E6400 w/ 4 GB RAM running Windows 7 Professional 64-Bit) that I need a wireless adapter for. Do you have any recommendations on a good choice? Looking at Newegg's best-rated adapters, I see quite a range from a $6.38 USB adapter to a $72.99 PCI Express adapter. I don't want to waste my time on something inexpensive that isn't going to work well. But I also don't want to waste my money on something that isn't going to do anything different than a less expensive one.
