DANGER pcmcia-wireless newbie

**xxosix** · 03-17-2005

Where to begin? Please help.
The hardware. This laptop didn't come with any documentation.
It has an empty pcmcia socket. It has a switch like an integrated
wireless device. When I flip the switch a light comes on, but I
don't know if there is a wireless module built in.
Here is lspci -vv for cardbus

I have two kernels to load from, the default for this distro (2.4.22-xfs)
and 2.6.11. Loading 2.4.22 I see an output for hermes and orinoco
as modules I think. I've compiled these options as modules and static into
2.6.11, but had to remove them after kernel messages like this:

Code:

Socket c157642c
PCMCIA ***DANGER*** unable to remove socket power

I have pcmcia-cs and documentation, but am unfamiliar with wireless networking.
For now I've removed all 2.6.11 kernel support for pcmcia-wireless.
thanks

Actually it would be better if you sent the print out from "lspci" without verbose mode first of all. That will show a few clues on what you have built in at your LapTop.

**loft306** · 03-17-2005

please paste the output of

Code:

lspci

and either

Code:

iwconfig

or

Code:

iwlist scan

also you may need to goto the 2.6.x kernel to get it working there is better support for wireless init

iwlist scan

Code:

eth0      Interface doesn't support scanning.

lo        Interface doesn't support scanning.

iwconfig

Code:

eth0      no wireless extensions.

lo        no wireless extensions.

When I first installed Knoppix 3.3, netcardconfig/DHCP detected two network interfaces,
eth0 & eth1. Seems like before I did a full upgrade these two devices changed in order
once or twice, ie, eth1 was PRO/100 then it became eth0. On a positive note, this new
kernel works excellent with everything else.
thanks

As from your printouts above there is no WLAN adapter enabled in your computer at the moment. I think you should check your Bios setup if your internal adapter is enabled or not. Some OS's (read windows) do overtake the bios settings if it feels to. :-/ And thats what some distros of Linux do as well, basicly it is done by the OS by reading the Bios information and forces the functionality from what it learned about it.
