Hello, Freebsd-wireless.
Now my router/AP is new hardware in new case, and it is not
overheating for sure.
AP's WiFi card is Ubiquity SR-71E MiniPCIe card. Client is Intel
Advanced-N card. When AP sends stable stream of data (like RDesktop
connection from WiFi client to computer on wired network), AP gives
big pauses sometime, with "ath0: stuck beacon; resetting (bmiss count
4)" message. These pauses long enough to RDesktop client notice them
and try to reconnect. But no client dissociation occurs.
Here is card:
ath0: <Atheros 9280> mem 0xd0000000-0xd000ffff irq 18 at device 0.0 on pci3
ath0: [HT] enabling HT modes
ath0: [HT] 1 stream STBC receive enabled
ath0: [HT] 1 stream STBC transmit enabled
ath0: [HT] 2 RX streams; 2 TX streams
ath0: AR9280 mac 128.2 RF5133 phy 13.0
ath0: 2GHz radio: 0x0000; 5GHz radio: 0x00c0
Here is AP settings:

Here is ath-related dmesg:

Here is my sources: "10.0-CURRENT FreeBSD 10.0-CURRENT #0 r249767M:
Mon Apr 22 22:22:47 MSK 2013".
I have old router with AR9220 card, which I could use as spectrum
analyzer, if I'm giving proper instructions how to setup in in such
way :)
