Summary: I bought this to get wifi in a 4 year old Toshiba laptop with a broken wifi antenna. The hardware might be ok, but the software (CD or download) is awful. After an hour of texting with customer service, I was treated to the distinction. Apparently my adapter was enabled but not operating.
Summary: My desktop PC is old, but this Netgear N-150 WiFi adapter installed in minutes and works like a charm. I have had this adapter for a couple of years now, and it always prompts me when it's time to update the software.
