Wireless connection keeps getting interrupted.

[thebestofall007]

Hello, I am having an issue with my wifi connection to my router consistently getting disrupted every 4-5 or so minutes (but not all the time). When I first installed kubuntu, I didn't have this problem. I am using Kubuntu 12.04 on a macbook pro 4.1 laptop with the broadcom BCM4321 wireless card. I have tried:
sudo iwconfig eth1 power off command, switching from network-manager to wicd network manager, resetting the router, tried making a script that disables wireless power saving that contains:
#!/bin/sh

/sbin/iwconfig eth1 power off and placing in the /etc/pm/power.d folder and naming the script "wireless".

the output to the /var/log/syslog of when this event is happening is here:

What it seems to be doing is disabling wireless channels whenever it feels like it, and consequently, my connection, so I have to go into wicd to connect again. It's getting obnoxious, and I have looked all over the internet for the solution but I can't find up-to-date information on this (as I have seen others have it with older versions of ubuntu/kubuntu have similar issues).

The sudo modprobe -r ssb and sudo modprobe wl commands had no output. Were they supposed to?

[Hadaka]

Hi, no output means it accepted the command.
please post the output of ..

and have you booted, unpluged the wired

Just got through rebooting and am using the wireless now as I type. It's still doing it, though.

[Hadaka]

Hi, looks like you may have at one time tried
to load the b43 driver...

Kernel driver in use: wl Kernel modules: wl, ssb
ssb and wl are conflicting...so lets
scrub out any of the b43 dependants and then
toss him and his buddies into the blackhole.
please do..

sudo apt-get remove --purge b43-fwcutter firmware-b43-installer
you may get an error mesg. or a not installed on this...not to worry
then do.

sudo gedit /etc/modprobe.d/blacklist.conf
add these 3 lines to the BOTTOM (last line) of the file..

blacklist b43
blacklist bcma
blacklist ssb
proof read...save..and close gedit
then..once again...please do..

sudo apt-get install --reinstall bcmwl-kernel-source
sudo modprobe wl
boot and test your wireless.
thanks.

[thebestofall007]

I have a line in the blacklist file that reads:

# replaced by b43 and ssb.
blacklist bcm43xx

What are they doing with that?

[Hadaka]

I "think" that is created when you load the
broadcome-kernel-source...sta..wl driver.
but, for whatever reason the ssb did not get
blacklisted...so go ahead with the commands
i sent.
thanks

[thebestofall007]

It's still doing it, unfortunately.

[wildmanne39]

Hi, I hope you do not mind me popping in I recommend removing the n from 802.11a/b/g/n to make it 802.11a/b/g in you router and see if that helps.
Thanks

Thanks

How so?

[wildmanne39]

Hi, you can usually go into your router settings by typing 192.168.0.1 then there should be a drop down screen that you can click on to change it.

The reason it may need changed is because many linux drivers do not work well with N speed.
Thanks

oh, it's through the router.

[wildmanne39]

Yes and you will need to be hard wired to your router to change the setting.
Thanks

[thebestofall007]

Yes and you will need to be hard wired to your router to change the setting.
Thanks

Done that and changed setting to the 72 mbps setting. The max setting is 150 mbps.
I have included a screenshot of the interface of my netgear wnr-1000v3 router that shows the mode i am using if you need it.


Wish me luck. I'll chime in if it's a go or not.


Thanks.

[wildmanne39]

I believe when you remove the n setting it should be set to 54mbs max.
Thanks

[thebestofall007]

Reverted my router to 54mb/s mode.

It's going good so far...

We'll see later on how it goes tomorrow....

[wildmanne39]

Fingers and toes crossed!!!

[thebestofall007]

She's still cookin'. The reduced top speed isn't a bottleneck because my dsl connection is capped at 1mbps (100 kb/s up/download speed) anyway, so no harm no foul.

Is it true that the 802.11 n driver itself is at fault or is this a kernel issue or an issue with the netgear router I have?

[wildmanne39]

Hi, yes some linux wireless drivers have issues connecting at N speed but as you said unless you have a real fast connection above 54 you do not need N speed.
Please mark the thread solved.
Thanks
