So this is the 4th and 5th purchase of an adapter of this sort. I absolutely love these adapters. On a computer, it can make any computer wireless. I have seen alot of people give low ratings but I believe s because they didnt read the instructions. They clearing give a warning that you must install the software before you do anything to funtion properly. I have never had a problem other than speed...but thats because my internet company SUCKS! Everytime I see one that I can get at steal I rack up. I just added these to the collection. I hooked one to a computer I bought at a yardsale for 15.00. Yep you read that right. Lady forgot it was on her on her table and didnt want to take it back it. I hooked this wireless adapter and now no more landline wire. I moved the computer to the playroom. AWESOME SAUCE!
