Hello, using Preview 4, I can't seem to get my Broadcom chip working.
This seems to be my card from "lspci":
Code:
03:00.0 Network controller: Broadcom Corporation BCM4310 UART (rev 01)
On a fresh sidux install, my card seems to be recognised and "iwconfig" see's it as "eth0" (ignore the eth0 stats, it's after I attempted to connect):
Code:
lo no wireless extensions.
eth1 no wireless extensions.
eth2 no wireless extensions.
eth0 IEEE 802.11b/g ESSID:"a" Nickname:"Broadcom 4311"
Mode:Managed Access Point: Invalid
RTS thr:off Fragment thr:off
Encryption key:***** Security mode:open
Link Quality=0/100 Signal level=-256 dBm Noise level=-256 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
I first installed bcm43xx-fwcutter and executed the script to install firmware and rebooted... However even then, "ifconfig eth0up" gives:
Code:
eth0up: error fetching interface information: Device not found
Also "iwlist s" gives:
Code:
lo Interface doesn't support scanning.
eth1 Interface doesn't support scanning.
eth2 Interface doesn't support scanning.
eth0 Interface doesn't support scanning : No such device
P.S. Netcardconfig see's the device as "0 eth0_Wireless_device_00:14:A5:E7:2A:BC_bcm43xx"
I would really appreciate the help in getting my wireless working.
Thanks in advance. |

You missed a space between "eth0" and "up". Since this operation failed (due to typo) the scan was destined to fail.
Try again, see what happens.

| You can also try 'ifup eth0'. If you have your essid and key set up, it will enable adapter and begin dhclient for you (or whatever dhcp program). |

Kelmo: God, such a trivial error on my behalf, thanks for pointing it out!!!
Anyway, with sidux 2007-01, my wlan is recognised and upon installing the firmware via bcm43xx-fwcutter, wireless works!!! Although at an abysmal connection rate of 11MB/s, browsing the web is just about bearable but installing software/dist-upgrading feel's like dial-up...
I've since blacklisted bcm43xx and installed firmware via ndiswrapper, now I have full speed 54MB/s, everything is fine! |

Hi Ajeet, I also only get 11mbs. But I don't know how to blacklist bcm43xx. Do you know of a link how to do this?Or is it simple to do?
Thanks |

| bcm4311 is one of the less supported Broadcom chipsets as of yet, but there are serious improvements to be expected for kernel 2.6.20.2 - right now the proposed patches are still extremely controversial, so I'm not confident about applying the conflicting proposals earlier without being able to confirm the effects myself. Performance will improve soon with 2.6.20.2, not up to the ~3 MB/s well supported chipsets can do, but probably up to 1.8-1.9 MB/s |

| Thanks for that. I'll be patient then. I must admit that wireless is getting better over time. |

I have the new kernel. Now what? I still only get 11mbs not 54. Is there something else I have to do?
Thanks |

firegrass - Sure, I can help you!
NOTE: The first time you do this, an internet connection is needed.
From Konsole, do as follows.
To begin with, login as root:
Code:
sux
Enter your password and then assuming you haven't already installed it:
Code:
apt-get update && apt-get install cabextract
Then:
Code:
cd /etc/modprobe.d/
kate blacklist
The file will open in Kate, now scroll to the bottom and on a new line
simply type blacklist bcm43xx. After saving and exiting,
return to Konsole.
Remove bcm43xx from detection:
Code:
modprobe -r bcm43xx
OK, now it's a bit more complicated as you need to have the Windows version
(.exe) of the wireless driver for your chip. If you have the same chip as
me, then download this:
ftp://ftp.hp.com/pub/softpaq/sp33001-33500/sp33008.exe
Then depending on where you downloaded the driver, for example:
Code:
cd /home/firegrass
cabextract sp33008.exe
This will extract the files from the .exe, I have these files saved on a USB
stick so I don't need a wired internet connection to setup ndiswrapper in
the future and recommend you do the same.
Now install the driver via ndiswrapper:
Code:
ndiswrapper -i bcmwl5.inf
ndiswrapper -m
To determine whether the driver has successfully installed, "ndiswrapper -l" should output:
Code:
bcmwl5 : driver installed
device (14E4:4312) present (alternate driver: bcm43xx)
The last stage is loading the ndiswrapper module
Code:
modprobe ndiswrapper
Using logic, ndiswrapper assumes that the wireless chip is "wlan0", however in my case it is "eth0". Therefore:
Code:
kate /etc/modprobe.d/ndiswrapper
and edit the line "alias eth0 ndiswrapper" to whatever you need to.
Now browse to K Menu > sidux > Network/Internet > Network card configuration and enter in your wlan details.
Happy 54MB/s browsing!!! |
