WiFi 802.11b support in ASL 4.0 Beta

I have a need for 802.11b (aka WiFi) support in ASL. The Hardware compatibility list for 3.3 Beta states:

Wireless PCMCIA Cards
=====================
In general all PRISM2 chipset based cards sould be supported, please refer
to http://www.intersil.com

However, it does not reference PCI wireless cards like the D-Link DWL-520+ or the Lucent/Agere ORINOCO PCI 11MBPS WIRELESS ADAPTER. Are PCI wireless cards supported?

Presently I have a D-Link DWL-520+ installed in my ASL beta testing machine, but it was not identified during the installation procedure.

After some research I may have the answer to my question.  The Intersil Prism User Matrix shows many manufactures of 802.11b cards including a few PCI based cards.  From this list the Aironet (now cisco) and the Zoom Telephonics card seem most promising.

I suspect that the driver used in ASL is the  linux-wlan project.   The  Hardware Compatibity page shows several tested PCI/Prism2 based cards.  It also notes that the DWL-520 from D-Link is supported. but not the DWL-520+.  The 520+ uses a TI chip set not the Prism chipset.

In short, the PCI cards of choice seem to be D-Link DWL-520 (not the 520+)and the Linksys WMP11 (except version 2.7).  Second choices might be the Aironet PCI352 or the ZoomAir 4105.

Hello Scotts.

Wireless PCI-cards are not supported.

ASL supports only wireless pcmcia cards (and pcmcia->pci adapters, of course).

Since only PC-Card to PCI adapters are to be supported, does this also mean ASL will support 802.11A Prism cards if available?

Also, why not support both PCI and PC-Card to PCI adapaters, is there a design or technical issue why one was chosen over the other?

Daniel,

Thanks for the response.  However, I am a little confused by your statement.

Wireless PCI-cards are not supported.
ASL supports only wireless pcmcia cards (and pcmcia->pci adapters, of course).
Am I wrong about the linux-wlan project providing the wifi driver for ASL?   The documentation for this driver claims support PCI prism2 cards.

You stated the astaro rationale to not support USB/wifi devices very clearly in a different thread.

Does PCI wifi have a similar rationale?

Hello Tester100, hello scotts.

The limitation of the supported wireless hardware to pcmcia-cards has neither design nor technical reasons.
And maybe (!) future versions of ASL will support pci-cards as well.

Astaro has, as every being, finite resources and therefore we limited the possible causes of trouble to get a usable and reliably first wireless capable version of ASL.

I have purchased a ZoomAir 4105 with a PCMCIA -> PCI adapter.  The adapter is based on the TI PCI1410.  I confirmed it by reviewing the chip markings on the adapter. This chip set is listed in the Hardware compatibility list for 3.3 Beta.

The ZoomAir 4105 is based on the PRISM2 chipset.   Intersil Prism User Matrix confirms this as well as the linux-wlan project Hardware Compatibity page.

However, the card is not detected at install time.  Does the WiFi configuration happen at a dirrerent time?  Is there something else I should be doing?

I brought up the machine even though the installer informed that I only had one interface card.   After completing the installation I logged in via ssh and performed and lsmod.
