Description

I have two D-Link DIR-320 (rev. A2) boxes and both of them have the same bug on Backfire 10.03.1-rc4. If start using wireless network intensively (torrent with 100 peer connections at 8mbit) I got such messages in dmesg:

After usually 15 minutes of heavy wireless network load router lockups completely or reboots. If I disable wireless - I never get these errors with any network load.

I believe this is somehow connected with b43 driver.

I have tried latest snapshots of backfire and attitude - still got the same errors and router seems to be less stable.

P.S.: one router is not used right now - so I'll be glad to test any configurations.

I have the same problem but wireless is disabled and most things (for instance luci) are working but slowly. cpu load is between 3.0 and 5.0. i'm running Backfire (r24038) on wrt54gs V1.1.

  • Priority changed from high to response-needed

Is this still the case on RC5 ?

comment:3 Changed 7 years ago by q0081@…

Hi jow,

my wrt54gs v1.1 is production, so i cannot upgrade to rc5 easily. i can confirm, that removing package kmod-b43 is solving the problem (if wlan is not needed). Am i right, that i cannot test kmod-b43 from rc5 in Backfire 10.03.1 rc4 (newer kernel ..)?

I can confirm this issue is gone with Barrier Breaker on both mine DIR-320 routers with b43 driver. I think you can close this ticket as no more comments have been reported during past 3 years.
