I have a 5 year old macmini which I connect to the Internet via wifi. I have an airport extreme located on the ground floor and the macmini is on the second floor. The Macmini is horrible at finding the signal and keeping it. My wife and I both have iPhone 5s, she has a dell laptop and I have a first gen iPad. All these other devices connect via wifi and work great throughout the house...just not the macmini.
Any options other than junking the macmini?
I have seen in the discussions complaints about the macmini and it's wifi connecting...very upsetting that Apple does not remedy this - the computer is fine in every other way and a new one is expensive!
