iwl3945: Network dropouts w/ flash-stream in firefox

[Sedat Dilek]

Hi,

I have here reproduceable network dropouts with my iwl3945 wlan device
when watching flash10 A/V streams in firefox-3.6.3.

My Linux-kernel is 2.6.34-rc4-git3 enriched with "iwlwifi: work around
bogus active chains detection" patch from wireless-2.6 GIT branch,
so-to-say I am on version as-of master-2010-04-12.

Furthermore, I also did a reboot of my xDSL-router-modem and a
coldstart of my notebook.

Some additional informations:

$ dpkg -l | egrep 'wpa|crda|regdb'
ii  crda
    1.1.1-0~svnr1515.3                    wireless Central Regulatory
Domain Agent
ii  wireless-regdb
    2009.11.25-0+c0.sidux.2               wireless regulatory database
ii  wpagui
    0.7.1-1~dileX+1                       graphical user interface for
wpa_supplicant
ii  wpasupplicant
    0.7.1-1~dileX+1                       client support for WPA and
WPA2 (IEEE 802.11i)


Need more infos?
Any hints? Any ideas?

Kind Regards,
