I am seriously confused. My devices all connect to my modem/router without problems. EXCEPT for my macbook (2010) which had been fine up until a few weeks ago. I didn’t worry about it much because I mostly use my Air2 in any case. That might seem simple… I thought perhaps the wifi was crapping out in the macbook, but it connects easily to other networks. There are Telstra Air networks within cooee and it connects to them, it connects happily to my phone and to my Telstra wifi gadget. But, it refuses to connect to the local network … a reboot of the modem fixes the problem until the next time.
