What I have checked so far:
- tcpdump on the Wi-Fi of the MB yields only its own packets plus the multicast packets of a friend's MBP (same generation). No other traffic is picked up.
- Torch in RouterOS shows packets from MB arriving and replies being sent out (which MBP does not see)
Config RouterOS:
- wireless-cm2 package
- RouterOS 6.33.3
- RB2011-UiAS-2HnD
Code:Select all

More findings:
- MBP's BSSID / channel still correctly reflect the RouterBOARD as the AP
- Disabling/Enabling TKIP/AESCCM/both does not fix nor break anything
- Disconnecting from the Wi-Fi gets seen by the RB (disconnected: station leaving)
- Wi-Fi debug logs show absolutely no useful information at all (attempts to associate, not in local ACL by default accept)
- Packet Sniffer tool confirms: MBP can send packets, but not receive them (it shows the TCP SYN from MBP, then SYN-ACK from server, then retransmissons of SYN-ACK (no ACK from MBP))
/ /编辑2: I *think* switching from wireless-fp to wireless-cm2 (to get the WMM-PowerSaving aka UAPSD) made the problem worse (or might have actually caused it). Sadly, this is required so the battery of my iPhone doesn't get drained within a day...
/ /编辑3: "Fixed" it by adding a script that turns Wi-Fi off on sleep and on on wakeup (of course this breaks PowerNapping and such things...)
