Looking for a solution to my wifi problem. I have just bought a new MacBook Air. I already own a 2007 model. I live in France for 6 months of the year. Where I live, I have wireless wifi access, which is restricted to 2 devices. Needing more than that, I got around it using the old MacBook with an Engenius EUB9801 USB dongle. This let me use the MacBook as a wifi hotspot. When I plugged the Engenius into the new MacBook......nothing, its not even recognised. Question is, has anyone found a way to make the MacBook Air into a hotspot? Please bear in mind, I am accessing wireless wifi, not accessed by any hard wire. There is no ethernet socket on the new MacBook. Any ideas?
