A while back I upgraded my DIR-628 to firmware 1.11. Checked today and noticed there had been a couple updates -- 1.12 and 1.13. When I tried to install 1.13, an error screen appeared, indicating that the file is incorrect. So I downloaded 1.12, which installed fine. Then I noticed that the names and sizes for the firmware files are very different.
1.12 -- dir628_firmware_112.bin -- 1,333 KB
1.13 -- Upgrader_DIR628_V113B03_E03.1 -- 2,320 KB
My router is hardware version A1. Is it not compatible with firmware 1.13?
