What problems were you having?

Have you tried searching for comments about the lw1100p in Google? I find to be very helpful with this sort of thing.

yes i tried. it looks like nobody ever heard about it. where i read things, they say there are four big manufacturers of wlan pcis but they don't mention lg. and this card is just perfect in windows. i tried suse 8.1 live eval. it didn't want to work. i just guess it's because the driver.

The LW1100P is a Prism2 board, running an Intersil firmware. (manfid: 0x0156,0x0002). You have to install the 'pcmcia' package on your desktop before you can use the card! It is basically made up of a PCMCIA card (like the LW1100N) and a PCI-Cardbus bridge, the TI PCI1211.

By default, the SuSE 8.1 associates the 'orinoco_cs' driver with this card. On my system, this driver can initialize the card (a correct beacon is sent), but 'dmesg' shows a bunch of errors that go like

eth2: Error -110 writing Tx descriptor to BAP

and have never managed to ping this box from my laptop.

I have then switched over to the wlan-ng driver (prism2_cs), with sort of success...:
No errors anymore in the system log, and a connection (I tried FTP) is working.
BUT: It's extremely slow, and I suspect the LW1100P equipped box of reducing the speed. I'll continue to work on that...

By the way, are you sure, your card is detected (cardctl should show the card details)? I had a nasty problem when starting the kernel with the 'mem=959M' parameter, needed to run VMWare on my 1GB RAM machine. I had to remove the 'mem' parameter for the PCMCIA subsystem to detect the card (the cardbus bridge was detected, but not the PCMCIA part). Looks like the kernel assigns a wrong virtual memory window to the card.

Please ask if you need more details.

Well, it detects the PCI-Cardbus bridge but I think it doesn't detect the other part. I tried bot the orinoco and the prism2 in Suse 8.1 Live Eval and nothing works. How could I change the 'mem ' parameter? Could you please send me more details?
Thank you.

LW1100P & Slackware 8.1 : same trouble

I have the same card and the same trouble as Mathias: It seems the pci bridge is recognized (TI 1211) but no eth or wlan appeared in dmesg. I tried to load orinoco modules from kernel 2.4.18 and 2.4.19, and also prism2, hermes, orinoco (PCI or CS) from both kernel and pcmcia_cs packages, but now way to see the "pcmcia" part.
By loading the wlan_ng (if I remember well) something happened (the light on the card was blinking) but no new network device available.
I'm desperate, of course! ;-)
Any clue?

Exclamation About LW1100P Linux drivers!

Hi there,

I have used for 3 years such cards (LG LW1100P) in an ISP environment, in the area of Snagov town from Romania.

You will ask me, probably to publish the drivers. Well, this is the problem. You know why I am writing here, now ? Because I've lost that drivers ( And I've tried hardly to locate them again on the net, without any success.

Well, next week I will go there - I remember that I have an old Pentium/266MMX there, that is working as a small router. The main link is made with that LW1100P (PCI card), equipped with a 24dB sectorial antenna. The distance between the access point and that card is about 3Km, and the link is working fine and without any problems at 4Mbps.

Hope to find on that old router the archives containing the drivers. If so, I will come back here to post a download link for them.

By the way, anybody here resolved the problem ?
Maybe I will not have to do that trip )
