Hi Nicolae,

The firmware update is not avaible at D-Link Internationl page because they ignore our alerts.

The D-Link Brizilian Team say that the patch created work with all versions and languages of D-Link 2100AP.

The link to direct download is http://www.dlink.com.br/internet/downloads/Wireless/DWL-2100AP/DWL2100AP-firmware-v210na-r0343.tfp

You can manual download it accessing the Link: www.dlinkbrasil.com.br/internet, click in the "downloads" link, which is at the right top of the page.

So click the "Wireless" folder, next click in the "DWL-2100AP" folder and you will see the patch avaible (DWL2100AP-firmware-v210na-r0343.tfp)."

If you are a D-Link International customer we recommend you to contact D-Link and ask for a patch. As much more clients request for security enforcement, D-Link and other vendors will see the need to deal with security problems.

Intersting note:

De: Niklas <maxxess@...>

This "flaw" also affects DWL-7100 (tested) and most likely DWL-7000 and possibly other ap:s. D-Link has no fw updates since 1.5 yrs back for the 7100/7000-series. Time to get one out now...

Regards
