Hi, I have an new iMac and i am very happy i switched over from dells but the only thing that is annoying is that about 3 times a week the internet connects using another persons and i have to go into the top right and click on my internet router number then go through a whole process of entering in the web key and user name of administrtor and it is very annoying but at the same time this happens i can use my dell laptop so i dont think it is the router io think there might be some settings i can change to make it stay with my wifi. I have a router about 20 feet away and connect it wifi. Just wondering y it keeps connecting to neighbors internet randomly. It isntr the worst thing just very annoying. Please help Thanks.
