Due to having older hardware and wanting the proprietary ATI driver, I am looking to run SL5. The livecd boots up fin on my laptop, the wifi light came on and I got excited, but I cannot connect.

I tried connecting via commandline, but dhclient would not lease an ip. it does see my wifi essid though.

An lsmod shows b43xx loaded, and since I have a 4311, thought that would suffice.

Any help?

What is the Vendor:Device ID pairing for your wireless device?

lspci -nn | grep -i net shows?

I'm currently running an old ubuntu distro, don't think that would affect it though?

Different distros mean different kernels, drivers and such.
I am sure there is a driver for SL, but it might be missing from the base EL5 system because of its age.

Thank you for the information. I've now checked it against an up to date EL5 system --

CODE

[Build64R5 ~]$ rpm -q kernel | sort
kernel-2.6.18-371.1.2.el5
kernel-2.6.18-371.3.1.el5
kernel-2.6.18-371.4.1.el5
kernel-2.6.18-371.el5
[Build64R5 ~]$ uname -r
2.6.18-371.4.1.el5
[Build64R5 ~]$ grep -i 14e4 /lib/modules/*/modules.alias | grep 4311 | sort
/lib/modules/2.6.18-371.1.2.el5/modules.alias:alias pci:v000014E4d00004311sv*sd*bc*sc*i* bcm43xx
/lib/modules/2.6.18-371.3.1.el5/modules.alias:alias pci:v000014E4d00004311sv*sd*bc*sc*i* bcm43xx
/lib/modules/2.6.18-371.4.1.el5/modules.alias:alias pci:v000014E4d00004311sv*sd*bc*sc*i* bcm43xx
/lib/modules/2.6.18-371.el5/modules.alias:alias pci:v000014E4d00004311sv*sd*bc*sc*i* bcm43xx
[Build64R5 ~]$

It clearly shows that the bcm43xx kernel module (driver) should be appropriate for your particular WiFi card.

I wonder if your problem may just be due to a lack of configuration of the wireless sub-system?

Any suggestions on how to proceed? I am a mid-level novice I guess. I would very much like to run el5, centos doesn't support my card at a kernel level. Oracle popped up as an option but they use a kernel that is too advanced for the vendor-supplied video driver i need. I was pretty psyched when SL found my card, but the auto-disconnect kinda kills it.

To be honest, the SL 5, CentOS 5 and RHEL 5 kernels are functionally identical. So I am surprised at your comment regarding CentOS . . .

However, let's see what can be done. For reference purposes, I had a look at a CentOS wiki page, Making Wireless work on your laptop (or desktop) and Section 3.1 led me to another page. A quick read of that latter page directed me to the ELRepo Project and the wl-kmod package.

Please have a look at the wl-kmod page and then follow the instructions to build your own copy of the kmod-wl package. If all goes well, that may be a viable solution to your WiFi problem. smile.gif
