Firmware archive for the D-Link DSL-2640U ADSL router, hardware revision T2, at 3.98 MB in RAR format. Hardware revision letters on D-Link devices identify different platforms, so the T2 marking on the label must match before flashing. The image serves to repair a bricked router through the recovery interface or by writing the flash chip with an external programmer. Look inside to see whether it is a full dump or an update file, back up the original memory first, and confirm the image fits.
