Update 16th January 2010: 1.33b01NA has been released.
Update 1: The 1.30 firmware now has a beta tag and is available at: ftp://ftp.dlink.com/Gateway/dir655/Firmware/dir655_firmware_130_beta.zip. Before downloading please read below as this firmware isn’t like the others:
It appears that D-Link have updated the firmware of the DIR-655 router to v1.30, however it has been pulled from their servers just after release,
if it becomes available again it should be at ftp://ftp.dlink.com/Gateway/dir655/Firmware/dir655_firmware_130.zip which is the link they had before it was pulled. The most likely reason for pulling the release is due to that fact that it cannot be downgraded once it is installed, coupled with the fact that it removed wireless B support makes it a bit of a gamble.
According to a D-Link forum admin:
The 1.30 Firmware has been taken down from the support site. It may do a little too much at once.
Removing 802.11b is not a bad thing for most people.
Conditions that make a firmware unable to be downgraded are not always avoidable.
Distributing a firmware that removed 802.11b and also will not allow the end-user to downgrade said firmware, could result in customer service or RMA issues neither the customer, seller, or manufacture desire.
Granted from what I have seen, people are reading the release notes and the warnings about the firmware, but I am looking to be on the safe side as the user base with access to the code made change (not read).
It may go back up because the benefits to the majority are to great, but for now we just need too take a closer look at the release.
It is available to download on some sites and people who have installed it are finding it to be a good release, but I urge people not to try it just yet as D-Link may put a new version out soon that can be downgraded or has wireless B support.
