When my old computer died I had to have a new one ASAP so I went to Wally World and bought an HP. It had Windows 7,a quad core processor and 6 gigs of ram for around $400. But it came with no on-board wireless. I decided to just swap over the wireless card from the old computer but it was a PCI card and the HP has only PCIe slots. None of the stores in my area carry a PCIe wireless adapter, just USB wireless adapters. I would have to order the PCIe card from New Egg or the like. Are their any issues with using the USB adapter vs the PCIe card?
