I have been playing around with getting my router updated but can't quite get there. I have the DSR-250 updated to 3.11B101H_WW but when I try to then load DSR-250_Ax_FW3.12_WW_common the router reports it's the wrong file. Reading the attached pdf for the 3.12 firmware, it mentions that the intermediate firmware would be DSR-250_A2_FW3.11B001E_WW (I have the A2 hardware version). DSR-250_A2_FW3.11B001E_WW isn't in the 3.12 zip file and I did a search and nothing has come up. What am I missing??
Thanks!
