I've had this problem for some time now and was wondering how many others have also run into it. Essentially, running an 802.11n AP and a MacBook client, the MacBook keeps dropping out every few minutes.
This only occurs using Mac OS X 10.6.3 (Snow Leopard) or above, on Broadcom-based AirPort cards. Running Windows via Boot Camp OR using an Atheros card OR an older version of Mac OS X OR 802.11g - and the problem doesn't show.
- R2N and an R52N
- RouterOS 4.3 to 5.0b2
- various different RB411 (411A, 411AH, 411U)
- tuning various settings on the AP
