My buddy is a computer science major and he set up 2 Wireless Networks Chiba1 and Chiba2, they have atleast 35% connectivity within a 10mile radius, when I airodump it shows him and his other comp using ALOT of bandwidth, but when you try to connect it always says limited connectivity!

Anyone else come across something like this before, got any suggestions, Its encryption is set to OPN, he said I wouldnt be able to figure out how he did it?
