13" rMBP 2013 wifi problems

[swmike@…]

I have a Macbook pro Retina from april 2013 (OSX 10.8 with all updates) and I am attending IETF87. Whenever I sleep the macbook and wake it up again, it won't connect to the wifi network. I have to turn off wifi, go into settings, delete the wifi SSID in advanced settings, turn radio on again, wait a couple of minutes, ten it figures out there is no network to connect to and stops trying, then I can select the ietf-a.1x wifi, enter ietf/ietf and it connects immediately. I have this problem in all places I have tried it, the Potsdam 1 and Belevue.

I have identical problem with the "event" SSID at the Pullman hotel, same workaround to get it running again. Is this a known problem?

I know that rMBP's have known wifi issues running older Mountain Lion code. If you are @ 10.8.4, then there may be a physical issue (although I wouldn't rule out some buggy OS X issue).

The fact that the issue follows you to the Pullman indicates a problem with the MBP, not the wireless, since the Pullman is simply broadcasting a beacon for IETF over their own WAP's.

There is a Mac Store about 2km from the event. I would suggest walking over there and seeing if they can check the hardware and maybe offer some answers.

Thanks for the pointers. The wifi is 100% stable as soon as I have connected, it will stay up for hours on end, and it even works when I walk between rooms ("handover").

So I would think it's more likely a bug/incompability on the wifi driver or kernel. We'll see if the problem persists when I get back home (I have no problems at home or anywhere else) and if I does I'll look for help from Apple.

Thanks again for the reply!

Good luck! I'm closing this ticket. Let us know if some other issue crops up that you would like to discuss.
