The problem can be avoided by enabling WiFi infrastructure in the kernel:

I have these lines in those boxes which build the kernel in common:

# Wireless NIC cards
device      wlan            # 802.11 support
options     IEEE80211_DEBUG     # enable debug msgs
options     IEEE80211_AMPDU_AGE # age frames in AMPDU reorder q's
options     IEEE80211_SUPPORT_MESH  # enable 802.11s draft support
options     IEEE80211_SUPPORT_TDMA  #enable TDMA support
device      wlan_wep        # 802.11 WEP support
device      wlan_ccmp       # 802.11 CCMP support
device      wlan_tkip       # 802.11 TKIP support
device      wlan_amrr       # AMRR transmit rate control algorithm
device      ath         # Atheros NICs
device      ath_pci         # Atheros pci/cardbus glue
device      ath_hal         # pci/cardbus chip support
options     AH_SUPPORT_AR5416   # enable AR5416 tx/rx descriptors
options     AH_AR5416_INTERRUPT_MITIGATION # AR5416 interrupt mitigation
options     ATH_ENABLE_11N      # Enable 802.11n support for AR5416 and later
device      ath_rate_sample     # SampleRate tx rate control for ath
