Open source wireless G options without voiding the warranty

How about a USB Ralink device, supported by the rt2x00 driver?

$40 CAD gets you a D-Link DWL G122:

This guy reports it works:

The only question is if it works on the Eee.  Anyone want to give it a go?

If anyone has made any USB wireless G device work with an open source driver on the Eee, not necessarily an Ralink, I'd love to know.

I'm using an older DWL-122 (B-only, prism2) as my scanning device for kismet, open source driver, etc.   Sticking with the stock built-in wifi for G access.

Ah, nice.  The earlier failure reported on these forums to replace the internal wireless G had me worried that you'd have issues with USB wireless too.  So I assume the G device I linked to would be no problem.

By the way, that failure, which involved the Intel Pro Wireless 3945 and "a different intel card" (reported by another user) is discussed here:

http://forum.eeeuser.com/viewtopic.php?id=2421

Apparently the BIOS will happily accept another Atheros card, but not an Intel.  Current thinking is that the BIOS is keyed to only accept cards from one vendor, which is why the Atheros-based Gigabyte N300 that TexasGuy used worked (but so far as I know that card isn't supported under Linux).

Be careful with what you get, both Linksys and D-link have been known to switch the internal chipset on a wifi card and not change the boxed model number (or change it slightly, but vendors tend not to publish them.)   If you've ever looked at the Linksys WRT54g router series, you will see that each one has a different setup, different levels of hackability and some even don't even run the same OS!   The same is true with their cards.

A quick google shows:  http://jeremydenise.net/en/node/189       that there is an open source driver from the chipset manufacturer for the DWL-G122:

the linksys WUSB54GC also appears to use the ralink driver:  http://www.linksys.com/servlet/Satellit … 9039789B08

Re: Open source wireless G options without voiding the warranty

I think you are talking about USB cards right ? The guys on the other thread are talking about a card that is on the PCIe bus. That is a completely different bus. The eee couldn't care about which chipset you have on the USB card. The PCIe bus is a different matter.  The USB "talks" with the OS through the driver while the PCIe bus works differently...
I could be wrong, but by now some you must know (I'll find out in two days, when I get my USB card with a Ralink chipset...)
