Iwlwifi problems with 3945 Part II

As I wrote earlier I've had some problems with the iwlwifi driver and my Intel 3945 wifi card. One workaround brought to my attention by again by Jeremy Olexa's blog post is to run G mode only.

This can easily be done in OpenWRT Kamikaze with:

ipkg install wl

In the config file /lib/wifi/broadcom.sh add the following line just after the killall statement:

wl gmode GOnly

Restart network/box.

With this workaround speed is back to normal, thanks to the initial blog post by Markus Golser here.

Så meget for privat livets fred og liberale friheder.

Tillykke med friheden til totalovervågning, der ville gøre selv Stasi glad.

Helpdesk software

At work we're currently running Bugzilla for internal issues and code changes. However we'd like to have a single system where we can handle both internal and external issues. The requirements so far are pretty simple:

Easy issue creation
Status web page for each issue
Internal comments not viewable by everyone
Open interfaces to easily integrate with other applications

I guess we could hack Bugzilla to comply with those requirements but I'm not sure if it's worth the effort. I've been looking briefly at Jira from Atlassian. It seems to suit our needs and provide a project management solution as well.

I'm very interested in hearing from people having tried using Bugzilla as a helpdesk system or from people having used Jira.

Helpdesk software : deadhead

Jaervosz, choose the right tool for the right job : bugzilla is not good for tracking requests but only for bugs as you have experienced.

Jira is on the right line, but it has a problem: co$$$t .

I suggest you another tool I use daily: RT, produced by Best Practical (http://bestpractical.com/rt/)

RT it is :
* open source
* free
* used by company/university all around the glob
* has huge documentation+wiki and an active ML
* designed with business in mind
* ready to use
* written in perl
* present in portage (maybe you could give help in keeping updated the ebuild - 3.8.0 is now out there but ebuild is still ~3.6.7)

As you can imagine the introduction of this kind of tool have to be planned carefully, but once you have clear the structure present in your working environment and the result you want to reach with RT, half of the job it's already done.

They organize course too, just in case you boss need some candy...

I started using it some months ago and we're vary happy with it. We have hundreds mail less in the box, we can track activities easily and information are more easily shared among the team.

Helpdesk software : jaervosz

Yeah, I've been hearing a lot of good stuff about RT too. Wrt Bugzilla, I know it's not the perfect tool for the job, however it is what we use internally and it would be nice if issues shouldn't move from one system to the other. OTOH the goals might be too conflicting and we'll have to use separate software internally and externally.

Thanks for your input.

Iwlwifi problems with 3945

I'm now back from a long period abroad on vacation and work.

Since my ARP issue I've experienced further problems with iwlwifi. Fresh after a reboot I have no problems but shortly after starting any large download, download speed will drop to around 100kb/s. It was both an issue with iwlwifi-1.2.3, hardened-sources-2.6.24-r3 and 2.6.25-r3. It seems like several other people are experiencing this in one form or another. Similar issues with ipw3945 have been reported here, here and here.

For now I've simply plugged in my good old Atheros AR5212 802.11abg NIC and configured Madwifi.

WPA performance is still way below maximum speed but it'll do until the new OpenWRT Kamikaze release later this month.

*SIGH* Now I'm again able to trigger some Kamikaze bug that cause the WRT54G box to reboot under high trafic. I really do look forward to the new Kamikaze release :)

Update: My card is a 3945 and I'm using latest iwl3945ucode-2.14.1.5 in portage.

Iwlwifi problems with 3945 : Donnie Berkholz

Try the 228.x iwl4965-ucode, it works a lot better for me. Make sure you're using the SLOT=0 one if you're not on 2.6.27 rc's yet.

Iwlwifi problems with 3945 : Gordon Malm

I'm sorry to hear of your iwl3945 wireless troubles. I've had perfect performance from an iwl4965 with hardened-sources-2.6.{24,25} kernels (connected to a madwifi-ng AP most of the time). While you're stuck with madwifi, give the minstrel rate module a try. I find it to perform much better than the default "sample" rate module.
