#1791: 1 second "freeze" every 2 minutes
-------------------------------+--------------------------------------------
Reporter: [EMAIL PROTECTED] | Type: defect
Status: new | Priority: major
Component: madwifi: driver | Version:
Keywords: | Patch_attached: 0

By "1s freeze", I mean that all packets are dropped for a duration of 1
second. It happens at a period of 121 seconds.
Radio interference? I don't really want to hear that because I have no
idea what could cause that and I tried everything:
* channels from 1 to 14
* laptop close-by the access point (and excellent link quality)
* CCK and OFDM at lowest rates (1M & 6M)
I suspect madwifi because I see that :
{{{
$ wlanconfig ath0 list
ADDR AID CHAN RATE RSSI DBM IDLE TXSEQ RXSEQ CAPS ACAPS
ERP STATE MODE
XX:XX:XX:XX:XX:XX 1 14 11M 17 -78 120 37905 63184 ESs
0 23 Normal WME
}}}
What does "IDLE=120" mean ???
I use madwifi on my access point:
* card: TRENDnet TEW-443PI [168c:0013]
* kernel: Linux 2.6.24.2 (dist: Debian/Etch)
* madwifi/branches/madwifi-0.9.4 (r3350)
My laptop:
* card: Broadcom BCM4318 [14e4:4318]
* driver: b43 (Linux 2.6.24.2)
Testcase:
* `ap$ nc -u client 2000 < /dev/zero`
* `client$ nc -ul 2000 > /dev/null`
* rate: 1Mbps to maximize reliability
* I read `/proc/net/dev` (column: Receive/bytes) every 100ms.
* I get the attached stats:
* 1 vert px = 1000 bytes
* 1 horz px = 100 ms
* there a green line every second
* and a red one every minute
* ~ 100 ko/s almost all the time
(Severy set to major because it breaks most media streamings.)
