I ran a backup on the router, had it email me. took the file and FTP it to a new router. went to restore with the new file and it says file is to big. I have done this before and it has worked. But it wont now.The first thing to backup is :
1. Go to files-backup --> to backup file, don't forget to see if ur files has been backup.
2. if u see the file and exist, you may restore it. i guarantee there will be no problem.
thx,
