Wifi Connection Issues

I connceted to Hot Air in a hotel 2 weeks ago and when I got home Hot Air tries to override my home Linkeys Wifi. It just keeps searching for Hot air and I am unable to connect to Wifi.. I am unable to delete Hot Air  unless I go in and disable my Wifi and then enable it. It then lets me delete it and I automatically connect to my home Wifi as I use to do before using Hot Air. Then in a few days Hot Air comes back and I have to go through the process all over again. I called Hot Air and they were unable to help me and said they never heard of this problem. I had tech help and they showed me how to delete it, but it keeps coming back. How can I get rid of it for good? In my searching I feel it may have something to do with something called WIFI Catcher????
