Code 10 with WPC11 Linksys on Win XP Pro

By AlJ ·
This is a WPC on a ThinkPad T22 with XP pro. WPC 11 was working then on re-IPL got code 10. I have uninstalled and re-installed to no avail. No other device conflicts as far as I can tell. Any ideas?

Code 10 with WPC11 Linksys on Win XP Pro

You can try disabling IRQ Sharing on the computer.

See Microsoft article Q279256, "How to Disable IRQ Sharing for 16-Bit PC Cards That Do Not Support ISA-to-PCI Routed Interrupts"

The information in this article applies to:

Microsoft Windows XP Home Edition
Microsoft Windows XP Professional

The R2 PC Card does not start, and you see the following error message in Device Manager:

This device is either not present, not working properly, or does not have all the drivers installed. (Code 10)

Try upgrading the device drivers for this device.

This behavior occurs because some R2 PC Cards do not support interrupt request (IRQ) resource sharing. In Windows XP, 16-bit PC Card (PCMCIA) PCI readers can use R2 PC Cards (the 16-bit ISA type) without requiring an ISA runner paddle to obtain ISA interrupts.

Code 10 with WPC11 Linksys on Win XP Pro

Nope, I need the IRQ sharing. Here is what I finally did. Since it is apparent that the Linksys devcie driver for the WPC11 version 1 card does not support IRQ sharing and it is also apparent to me that the support at Linksys is very bad I instead put a Siemens Speedstream 1021 card in the ThinkPad T22 and declared victory. The Linksys had worked after the fresh install of XP but it failed to work once I installed IBM ThinkPad T22 specific drivers from IBM. Once I dropped the Speedstream in it took me about 5 minutes to have the T22 up and running. I have been in this business for 30 years and Linksys takes the cake for having a really crummy device driver on this card. I spent in excess of 6 hours trying to fix their problem.

What did I give up? Well, the WAP11 access point from Linksys only supports 128 bit encryption in a proprietary fashion, so I had to step down to 64 bit (40 bit) encryption with the Speedstream. I went out today and bought 2 more. Adios Linksys.
