Apple hardware doesn't play nicely with certain mobile WiFi chipsets. I've tried tethering with various Macbook Pros and all of them showed the disconnection problem. Tried it with the Lumia 920, the galaxy S4, the Galaxy S3, the HTC One. The problems were worst with the Lumia, however, even with the iPhone 5, the connection isn't very stable.
As for your question: the problem's on your MBA and not the Lumia and there's no solution to it except for switching your phone or your computer. Used tethering for 5 hours with my Surface Pro last week and it never dropped the connection once. With my rMBP, it won't hold it for even a minute and sometimes it makes the computer's WiFi card crash altogether, requiring a reboot.
Hi All!
I have a Macbook Air (from school so I can't put Windows on it). When I enable Internet Sharing on my Nokia Lumia 920 and use it with my mac it disconnects randomly for no reason. Can anyone help me with this?
