I recently upgraded the firmware on my DSL-2870B to Version 2 as D-Link claimed better wireless and they were right it is much better range and signal
However now when I go to GRC.COM and run the shields up test ports 0 and 1 are no longer stealthed but merely closed. The menu option to "ignore all pings" checkbox is also gone. Rather disapointed there D-Link. I have had it escalated to a LVL 3 tech who has escalated it to R&D! Wouldn't you just have a basic block of code that you wouldn't mess with and build features on top of rather than remove the basics! Waiting for another Firmware update that hopefully lets me re-stealth ALL my ports..
