Hello,

I think I got ripped off on ebay but I'm not sure about it.

Here's the story: I bought a Tekram PCF200 Wireless LAN-card for my notebook. Before the purchase I checked the drivers to make sure it uses a chip supported by Linux. As you may already know this chip uses the Prism 2.5 chip.

I got this card very quickly but when I put it into my notebook ( using a custom kernel v2.6.1 and its drivers for the card) I got the following errors in my log-files:

/var/log/messages

I also tried 2.4.23 and 2.4.24 (with their drivers) but they say the same and are less informative:

/var/log/messages

#Jan 16 18:37:53 schleppi cardmgr[95]: socket 1: Linksys WPC11 11Mbps 802.11b WLAN Card

/var/log/syslog
#Jan 16 18:37:54 schleppi cardmgr[95]: get dev info on socket 1 failed: Resource temporarily unavailable

So I tried this card in two other notebooks with Windows 2k and Windows ME. The cards were detected but they were never initialised correctly (with the oh so nice "Code 10" error message) and it always had the exlamation mark in the device manager.

What I'm wondering now is why is it detected as a WPC11. I know that it is a card with the Prism chip as well but it's not a Linksys card but a Tekram. The second is that it says that the card has a too old firmware.

I haven't found much information about old firmware versions but it seems to me that this message just means that it just gets bogus when it tries to read the information on the card.

So I've contacted the vendor about my suspicions but she hasn't answered yet.

I tried to gather a little more information and found this text: http://linux.junsun.net/intersil-pri...roken_card.txt

What I did afterwards was getting the hostap drivers from the CVS and installed them. Suddenly I didn't have only one but two new network interfaces: wlan0 and wifi0. None of them however were able to accept settings from `iwconfig`.

So I continued to follow this text's suggestions and loaded the firmware files mentioned there into RAM and suddenly wlan0 was acting as it was supposed to. I could set and get information. The only thing that didn't work was getting a connection to get an IP address from my accesspoint/router. But the card was blinking so something was going on.

So the card acts like it's working but it still doesn't. Is there a way how I can identify the card's firmware correctly (assuming there is a correct firmware on it)?

I also sent an email to Tekram Support but I doubt that they will hand out much information.

Thanx in advance for your help

If you bought a wireless card on ebay, to use with linux. Yeah, ya got ripped off. Manufacturers change their chipsets very often. Most of them migrate towards things that are much less linux friendly. The card should have updateable firmware, but that's only accessible from windows so...

I can sing a song about wlan chips not working with linux but this was a different experience (RealTek, AMD, ACX100 - there is a Linuxdriver for some of them but there hella unstable). It it wasn't using a Prism chip or something similar the kernel would have just said that it found an unknown card and the hostap drivers wouldn't have worked either.

So that is not the problem.
