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: 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: > ifconfig ath0 ath0: flags=8843 metric 0 mtu 2290 ether 00:15:6d:85:5f:fc nd6 options=29 media: IEEE 802.11 Wireless Ethernet autoselect mode 11ng status: running > ifconfig wlan0 wlan0: flags=8843 metric 0 mtu 1500 ether 00:15:6d:85:5f:fc inet 192.168.135.1 netmask 0xffffff00 broadcast 192.168.135.255 inet6 fe80::215:6dff:fe85:5ffc%wlan0 prefixlen 64 scopeid 0x6 inet6 2001:470:923f:2::1 prefixlen 64 nd6 options=21 media: IEEE 802.11 Wireless Ethernet autoselect mode 11ng status: running ssid home.serebryakov.spb.ru channel 3 (2422 MHz 11g ht/40+) bssid 00:15:6d:85:5f:fc regdomain ROW country DE ecm authmode WPA2/802.11i privacy MIXED deftxkey 3 AES-CCM 2:128-bit AES-CCM 3:128-bit txpower 30 scanvalid 60 protmode CTS ampdulimit 64k ampdudensity 8 shortgi wme burst dtimperiod 1 -dfs Here is ath-related dmesg: ath0: stuck beacon; resetting (bmiss count 4) ath0: stuck beacon; resetting (bmiss count 4) ath0: stuck beacon; resetting (bmiss count 4) ath0: ath_bar_response: huh? bar_tx=0, bar_wait=0 ath0: stuck beacon; resetting (bmiss count 4) 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 :) -- // Black Lion AKA Lev Serebryakov
