BCM43225 and limitation UK/Europe Channels 12/13

[chili555]

I actually think the STA driver is correct; however, if it's working well with the exception of channels 12 and 13, then I guess brcmsmac is no better or worse than STA.

If you have done this:

Also setting the /etc/default/crda to
Code:

REGDOMAIN=GB

...and this:

You might try this:

sudo gedit /etc/modprobe.d/cfg80211.conf

Add one line:

options cfg80211 ieee80211_regdom=GB

Proofread, save and close gedit. Unload and reload brcmsmac:

sudo modprobe -r brcmsmac
sudo modprobe brcmsmac

And you've checked the router for any available changes, then you've done all I know to do.

Yep done all that.

I'm actually considering trying to connect to my AP via terminal mabe i can get some clues.

Do you reckon i would have better luck installing b43 as far as i know it should support my card?

Broadcom Corporation BCM43225 802.11b/g/n [14e4:4357] (rev 01)

The vendor and product ids are actually in b43's loyal sidekick, ssb. As you can see, 4357 isn't included:

chili@LAPTOP60:~$ modinfo ssb | grep 4357
chili@LAPTOP60:~$

So, no, b43 won't work.

With Network Manager running, it is doubtful you'll connect or even see any significant clues in the terminal. You might instead check here:

sudo cat /var/log/syslog | grep -e etwork -e wl | tail -n25

That's wierd this http://linuxwireless.org/en/users/Drivers/b43#Supported_devices
seems to imply it is. Whats up with that?

I don't know for sure. I just read modinfo and report what I see. You can always try and report.

I did some more digging and did some research on brcmsmac and apparently it's a known problem.
Here's a thread on it:

and a related blog post

O please somebody tell me this is getting backported and punt into ubuntu.

Amazing! I was trying to get my wife's laptop up and running for the past 3 hours... until I run into this thread! Ubuntu community is great!

So, I switched from channel 13 to channel 10 and wireless is up and running now! It's good wireless networks aren't many in my area!

Laptop is HP DV6-7032TX

Same problem here in Australia with a BCM4314.
Looks like I'll have to go to my backup install of Ubuntu 10.10 - thank goodness for Clonezilla

Has this been reported as a bug on Launchpad so that the devs know that it is a problem?

[praseodym]

Thats a known bug with the Broadcom station driver. Try the native one:

sudo modprobe -rfv wl
sudo modprobe -v brcmsmac

Check:

iwconfig
iwlist chan
sudo iwlist scan
dmesg | grep brcm

You are sure with BCM 4314? Please check:

lspci -nnk | grep -iA2 net

Here are the results of the commands you suggested.

Do you have a link to this bug on launchpad so I can keep track of when it is resolved?

Thanks in advance,
