Hi,I have dir 855 ,h/w version A2,firmware 1.21 N.A.I brought this router refurbished.when i attempt to upgrade its firmware i get an error message
The uploaded firmware file may not be correct. You may have uploaded a file that is not intended for this device, or the uploaded file may be corrupted. If the uploaded file is correct, it is possible that the device may be too busy to properly receive it right now. In this case, please try the upload again. It is also possible that you are logged in as a 'user' instead of an 'admin' - only administrators can upload new firmware.
The Gateway will not be reprogrammed
