If you're here, it means you also have a Dlink 400 router.
I asked DLINK but they didn't answer my question. I asked DLINK support again, but this time no answer (2 weeks later).
In DLINK FTP site there is no firmware for DIR-400.
Past year, Googling around Russia, I found a FIRMWARE_DIR400_v1.02B03.bin.
But I am trying to figure out if is there any update, a 1.03 version or superior.
Can anyone tell me why DLINK doesn't show this firmware update on their site, and if this DIR-450 is compatible with mine?
