WPA2 with USB adapter?

    I've been a user of Linksys products for some time, but my use has significantly increased since I got high-speed a couple of weeks ago :biggrin:

    I have a WinXP SP2 PC that I'd like to connect wirelessly to my wrt54gl using WPA2. While I would like to get the WUSB54GSC, it doesn't seem to be supported by Linksys Canada.

    My other options are the WUSB54GC and the WUSB54G, but they only (officially) support WPA. Their prices are similar. Are there significant performance differences between the two?

    I've read posts here that suggest I can use third-party drivers to get WPA2 functionality. (I've already got the Microsoft WPA2 hotfix.) Is this possible with either of the two aforementioned models? If so where would I download the applicable drivers?

    TIA for helping a noob,

    The WPA2 vs. WPA functionality is a function of the OS/supplicant rather than the adapter (driver) to the best of my knowledge. However, the driver/adapter must support AES encryption. I.e. if you have the MS patch, any of those adapters should work. I have a WUSB54GS (which is near-identical to the G) which runs with WPA2/AES on XP.

    Thanks HennieM for your response.

    The WUSB54G is being (or has just been) discontinued, so I think I'll try the GC. Since the Linksys drivers seem old (2005), I've determined that the GC uses Ralink drivers, and I've downloaded the latest ones from Ralink's site.

    I'll be busy with exams, so I'll probably investigate further in a few weeks.

    Thanks again.

    Just an update:

    I bought the WUSB54GC (on sale :) ) and have installed it.

    I first installed the WPA2 update for XP (KB893357), and a couple of hotfixes for handling hidden SSIDs (KB917021 and KB907405). Instead of using the Linksys installer, I simply had Windows search the CD for the drivers -- I didn't want the Linksys network monitor installed. I then upgraded to the Ralink chipset drivers.

    The USB adapter connects reliably to my WRT54GL using WPA2 (AES). As a test, I downloaded SP3 for XP (315 MB). My only concern is that, with large downloads, I get a BSOD if SSID broadcast is disabled. Since "hiding" the SSID provides little added security, I'll just leave SSID broadcast enabled. However, if anyone knows of a remedy for this, please let me know.
