I have just gotten the mac80211 code for the RTL8192CU devices for integration into wireless-testing and then to mainline. All seems to be working, but I get a lot of disassociation./reassociation messages followed by a call to CRDA. The output from an 'iw event -t -f' command is the following: 1295294459.884470: wlan22 (phy #4): connected to c0:3f:0e:be:2b:45 1295294530.254474: wlan22 (phy #4): unknown event 64 1295294537.006563: wlan22 (phy #4): scan started 1295294538.642236: wlan22 (phy #4): scan finished: 2412 2417 2422 2427 2432 2437 2442 2447 2452 2457 2462 2467 2472, "" 1295294538.738591: wlan22 (phy #4): deauth 00:1f:1f:c8:8e:cb -> c0:3f:0e:be:2b:45 reason 4: Disassociated due to inactivity [frame: c0 00 00 00 c0 3f 0e be 2b 45 00 1f 1f c8 8e cb c0 3f 0e be 2b 45 00 00 04 00] 1295294538.738858: wlan22 (phy #4): disconnected (local request) 1295294538.779587: phy #0: regulatory domain change: set to world roaming by the wireless core upon initialization request 1295294538.861421: wlan22 (phy #4): scan started 1295294539.894265: wlan22 (phy #4): scan finished: 2412 2417 2422 2427 2432 2437 2442 2447 2452 2457 2462 2467 2472, "lwfdjf_rad" 1295294539.937094: wlan22 (phy #4): auth c0:3f:0e:be:2b:45 -> 00:1f:1f:c8:8e:cb status: 0: Successful [frame: b0 00 3a 01 00 1f 1f c8 8e cb c0 3f 0e be 2b 45 c0 3f 0e be 2b 45 a0 52 00 00 02 00 00 00 dd 09 00 10 18 02 02 f0 04 00 00] 1295294539.941963: wlan22: unknown event 19 1295294539.948184: wlan22 (phy #4): assoc c0:3f:0e:be:2b:45 -> 00:1f:1f:c8:8e:cb status: 0: Successful [frame: 10 00 3a 01 00 1f 1f c8 8e cb c0 3f 0e be 2b 45 c0 3f 0e be 2b 45 b0 52 11 04 00 00 03 c0 01 08 82 84 8b 96 24 30 48 6c 32 04 0c 12 18 60 dd 09 00 10 18 02 02 f0 04 00 00 dd 18 00 50 f2 02 01 01 80 00 03 a4 00 00 27 a4 00 00 42 43 5e 00 62 32 2f 00] 1295294539.948508: wlan22 (phy #4): connected to c0:3f:0e:be:2b:45 1295294637.011546: wlan22 (phy #4): scan started 1295294638.646848: wlan22 (phy #4): scan finished: 2412 2417 2422 2427 2432 2437 2442 2447 2452 2457 2462 2467 2472, "" 1295294638.726666: wlan22 (phy #4): deauth 00:1f:1f:c8:8e:cb -> c0:3f:0e:be:2b:45 reason 4: Disassociated due to inactivity [frame: c0 00 00 00 c0 3f 0e be 2b 45 00 1f 1f c8 8e cb c0 3f 0e be 2b 45 00 00 04 00] 1295294638.726940: wlan22 (phy #4): disconnected (local request) 1295294638.764810: phy #0: regulatory domain change: set to world roaming by the wireless core upon initialization request 1295294638.845333: wlan22 (phy #4): scan started 1295294639.862231: wlan22 (phy #4): scan finished: 2412 2417 2422 2427 2432 2437 2442 2447 2452 2457 2462 2467 2472, "lwfdjf_rad" 1295294639.899905: wlan22 (phy #4): auth c0:3f:0e:be:2b:45 -> 00:1f:1f:c8:8e:cb status: 0: Successful [frame: b0 00 3a 01 00 1f 1f c8 8e cb c0 3f 0e be 2b 45 c0 3f 0e be 2b 45 40 98 00 00 02 00 00 00 dd 09 00 10 18 02 02 f0 04 00 00] 1295294639.902684: wlan22: unknown event 19 1295294639.905854: wlan22 (phy #4): assoc c0:3f:0e:be:2b:45 -> 00:1f:1f:c8:8e:cb status: 0: Successful [frame: 10 00 3a 01 00 1f 1f c8 8e cb c0 3f 0e be 2b 45 c0 3f 0e be 2b 45 50 98 11 04 00 00 03 c0 01 08 82 84 8b 96 24 30 48 6c 32 04 0c 12 18 60 dd 09 00 10 18 02 02 f0 04 00 00 dd 18 00 50 f2 02 01 01 80 00 03 a4 00 00 27 a4 00 00 42 43 5e 00 62 32 2f 00] 1295294639.906219: wlan22 (phy #4): connected to c0:3f:0e:be:2b:45 The MAC address for the device is 00:1F:1F:C8:8E:CB and that of the AP is C0:3F:0E:BE:2B:45, thus corresponding with the above output. Is scanning this often normal? I suspect it is, but I have not looged the events before. Although both AP and STA support 802.11n, the connection is 802.11g (max 54 Mbps) using WPA2-PSK. What triggers the "Disassociated due to inactivity"?
