#22008 new defect

Wifi connection dropping randomly

Reported by: Mushoz Owned by: developers
Priority: normal Milestone: Designated Driver (Trunk)
Component: base system Version: Trunk
Keywords: Cc:

Description

Router: TP-Link wr1043nd v2
Openwrt Version: Trunk r48973 (but I experience the same problem on Chaos Calmer Stable release)

Problem: The wifi connection on my router randomly stops working. Ethernet connections to the router are fine, and can still access the internet. On some devices the wifi connections stays "connected", but the connection is completely dead. Pings to the router are not possible. On other devices the connection drops completely. The SSID is still visible in the list of available wifi connections, but I am unable to connect.

I had a look on the Luci wifi status page during such a lockup. The signal strength showed 0 dBm, while the noise value was in a normal range (-96 dBm). The Bitrate was displayed as 0.0 Mbit/s. The percentage bar showed 0%.

Workaround: Running the 'wifi' command resets the wifi and temporarily fixes the issue until the next lockup comes along. I haven't figured out what triggers this bug. It seems rather random.

Sorry for the late response. I had to wait for the issue to crop up again to capture the logs during a hang. This is the kernel log as the wifi was frozen (I accessed the router via ethernet):

Is there any other information I can provide that will be helpful in fixing this bug?

comment:4 Changed 22 months ago by Mushoz

Ayone? This issue is driving me nuts.

comment:5 follow-up: Changed 22 months ago by diizzyy@…

Stuck Beacon errors might occur if you're in a noisy environment, do you lots of 2.4GHz nearby?

comment:6 Changed 22 months ago by Mushoz

Yes, I'm in a very noisy environment. At any time, over 20 SSIDs are visible. I understand that this could result in a high percentage of dropped packets and slow throughput, but this shouldn't result in the wifi connection simply becoming inaccessible, right? Since the 'wifi' command instantly fixes the issue, it tells me that normal operation should still be possible.

Replying to diizzyy@…:

I noticed that I accidentally added a separate comment rather than replying to yours. Please see my separate comment as my reaction to yours.

The same issue on asus n56u, wifi drops completely, wired works ok.
