Dear all, I have a problem RTl8723 wifi connection. I can connect the access point fine but exactly 10 seconds later, the connection will be lost. This is 100% reproducible. Here is the "iw event" log. --- 1351707196.317590: wlan0 (phy #0): scan started 1351707197.302943: wlan0 (phy #0): scan finished: 2412 2417 2422 2427 2432 2437 2442 2447 2452 2457 2462 2467 2472, "" 1351707210.124514: wlan0 (phy #0): scan started 1351707211.109857: wlan0 (phy #0): scan finished: 2412 2417 2422 2427 2432 2437 2442 2447 2452 2457 2462 2467 2472, "" 1351707212.091111: wlan0 (phy #0): scan started 1351707213.075847: wlan0 (phy #0): scan finished: 2412 2417 2422 2427 2432 2437 2442 2447 2452 2457 2462 2467 2472, "WHRG300N" 1351707213.125596: wlan0: new station 00:24:a5:b4:d6:28 1351707213.128086: wlan0 (phy #0): auth 00:24:a5:b4:d6:28 -> 74:e5:43:d3:83:1f status: 0: Successful [frame: b0 00 3a 01 74 e5 43 d3 83 1f 00 24 a5 b4 d6 28 00 24 a5 b4 d6 28 40 02 00 00 02 00 00 00] 1351707213.190419: wlan0 (phy #0): assoc 00:24:a5:b4:d6:28 -> 74:e5:43:d3:83:1f status: 0: Successful ... 1351707213.190577: wlan0 (phy #0): connected to 00:24:a5:b4:d6:28 1351707222.948847: wlan0: unknown event 20 1351707222.965529: wlan0 (phy #0): deauth 74:e5:43:d3:83:1f -> 00:24:a5:b4:d6:28 reason 4: Disassociated due to inactivity [frame: c0 00 00 00 00 24 a5 b4 d6 28 74 e5 43 d3 83 1f 00 24 a5 b4 d6 28 00 00 04 00] 1351707222.965603: wlan0 (phy #0): disconnected (local request) 1351707222.979348: phy #0: regulatory domain change: set to world roaming by the wireless core upon initialization request 1351707222.982223: regulatory domain change: set to JP by a user request --- Does anyone have the same problem? Can someone tell me what is "wlan0: unknown event 20"? I suspect this is the cause of the disconnection. I am no wifi expert. Where should I take look at in the source code? I am using Fedora 16 kernel 3.4.9 with some minor patches and Realktek driver provided from my vendor, "8723AE_linux_WiFimac80211_0007.0809.2012.tar.gz".
