I had to realize that I can no longer log in to the bootloader adam2 after I had installed OpenWrt about it once. That means it always worked well when I hadn't installed OpenWrt with the username and password (adam2) to log in. After I have installed OpenWrt I always get an error message after the password entry and therefore it is now only possible to upgrade OpenWrt via luci or opkg... does anyone know what that can be?
Please show us the FTP session log including the error message.

Try lowercase adam2 as user/password, and perhaps also use PASS instead of PWD.
