Question WIFI canīt connect on channel 1 or 11


Hi every one, Iīm having an issue and I would like you to help me solve it.

The case is this: I have a laptop Dell INSPIRON 1545 which has a broadcom wifi, iīm using debian squeeze and the problem is that I canīt connect to any wifi which is using channel 1 o 11 ( I can connect on any wifi with channel 6), and when I query my system with iwconfig it says that this card supports working on those.
Please If anyone have a solution I will appreciate the cooperation.

note: I have installed already the driver b43-llph...(canīt remember exactly but if needed let me know).

It's much more likely to be other issues than the channel number. I'm reading this that you can connect to some wifi setups, and not others. Run the command
Quote:
iwlist wlan0 scan |less
and post results for only two channels - one you can connect to and one you can't. Tell us which is which. Don't post the whole output.

Looking at that, When you connect, you're mode is managed
When you can't connect, your mode is master. Shouldn't be master, unless you're the hot spot.

Also might try other live cd's from different bases. I'd be thinking that the device you have is slightly off frequency. If other distro's fail exactly the same then that might be the case. If windows works then we might consider the driver is faulty.

Yep JEFRO I can connect with win7 to every wifi listed above, but with debian I have that issue.
Business_kid which live cd distro you recomend me because debian live have the same problem (as logic).

And thanks you both for answering

Try Fedora and maybe Opensuse for a test.


Since you say Windows works then we tend to assume that the nic is OK at this point. It is still an assumption.

Hi you all, I found these on Debian wiki and it works really great for my wifi card, so I'm putting it in case any one else need to solve this issue, thanks to all who answered before.

Squeeze

1.

Add a "non-free" component to /etc/apt/sources.list, for example:

# Debian Squeeze/6.0
deb http://ftp.us.debian.org/debian squeeze main contrib non-free

2.

Update the list of available packages. Install the module-assistant and wireless-tools packages:

# aptitude update
# aptitude install module-assistant wireless-tools

3.

Build and install a broadcom-sta-modules-* package for your system, using Module-Assistant:

# m-a a-i broadcom-sta

4.

Blacklist the brcm80211 module, to prevent it conflicting for support of BCM4313, BCM43224 and BCM43225 devices:

# echo blacklist brcm80211 >> /etc/modprobe.d/broadcom-sta-common.conf

5.

Rebuild your initial ramdisk, to blacklist modules defined at /etc/modprobe.d/broadcom-sta-common.conf within initramfs:

# update-initramfs -u -k $(uname -r)

6.

Unload conflicting modules:

# modprobe -r b44 b43 b43legacy ssb brcm80211

7.

Load the wl module:

# modprobe wl

8.

Verify your device has an available interface:

# iwconfig

9.

Configure your wireless interface as appropriate. See also known issues.

Wheezy

1.

Add a "non-free" component to /etc/apt/sources.list, for example:

# Debian Wheezy (testing)
deb http://ftp.us.debian.org/debian wheezy main contrib non-free

2.

Update the list of available packages. Install the relevant linux-headers and broadcom-sta-dkms packages:

# aptitude update
# aptitude install linux-headers-$(uname -r|sed 's,[^-]*-[^-]*-,,') broadcom-sta-dkms

This will also install the recommended wireless-tools package. DKMS will build the wl module for your system.
3.

Unload conflicting modules:

# modprobe -r b44 b43 b43legacy ssb brcmsmac

4.

Load the wl module:

# modprobe wl

5.

Verify your device has an available interface:

# iwconfig
