So my aunt has as old iMac that doesn't have wireless internet, and is connected to the internet router through a chord. She uses this computer for emails and everything because all her information is on the computer and she isn't keen to change. This creates a problem for my cousin and I because the router is now limited to chords length on the computer, and doesn't send signal everywhere in the house. Firstly the house is rather big, but also it's an old heritage house and has think, solid walls. We tried getting a bigger, better antena to boost the signal, but it's still hasn't completely work. My question is this, is there someway to give the imac wireless capabilities, thereby freeing the router from it's current spot, and allowing us to position it where everywhere gets signal?
