So my wireless connection was working perfectly until yesterday, when I noticed I was picking up a new signal. Now I can't select my home network anymore, it just says "There was an error joining the Airport network "xxx"." I'm sure this new signal that I'm picking up is the problem. How can I get rid of it? Also the weird thing is, my PC which is also wireless wasn't affected by the new signal. Any help would be much appreciated. PS: My knowledge of this aspect of computers is really limited, I don't have a clue about proxies, PPPoE, DHCP or any of that stuff, so please bare that in mind .
