Hi all,

Does the "Intel Next-gen Wireless-n 802.11a/b/g/n Mini Card" in the
new
Notebooks from e.g. Asus & Dell's Inspiron 1720 / 1721 work with
OpenSUSE 10.2?

Dunno.

Check there.

Thanx Kai,

Pardon, I meant OpenSUSE 10.2. (Changed the Subject too)

I can't judge if this card works or not (I'm not that knowledgeable on
this technology). I am about to order some notebooks for the company.
They have to be able to run Linux. They can be ordered with either Intel
Pro Wireless 3945 802.11a/b/g-Minicard or the Intel Wireless-N-Minicard
Next Gen. The new N-Minicard would be nice, if it works.

But it seems that something is in the coming. I googled some more and
found this:

4.10.1 The device
The Intel PRO/Wireless 4965 is the fourth 802.11 product designed by
Intel, following the previous PRO/Wireless 3945 product (section 4.8).
It mostly adds support for draft-802.11n support, i.e. MIMO.

MIMO uses multiple antennas to simultaneously transmit or receive
signal, and using some clever processing can achieve much greater range
or speed than regular transmissions. The 802.11n standard is not yet
finalised, which is why those products are called draft-802.11n
compliant. It offer bitrate up to 300 Mb/s (most users won't see that in
practice), and may double the range indoors.

Like their previous chipset, the 4965 is only available as a MiniPCI
card for Intel Centrino processor, integrated in various laptops, and
not available as a separate add-on card.



4.10.2 The driver
For the 4965, Intel decided to directly based their driver on the new
mac80211 kernel stack (see section 4.9). This driver is part of the
iwlwifi package, and currently requires a version of mac80211 with Intel
changes to support draft-802.11n. This driver also require a specific
firmware the ensure regulation compliance.

I've taken the liberty of sending a cc to the two names that seem to
maintain this project (hope they don't take offence). I joined the
mailing list and posed my question there as well. I will post the answer
here as well.
