A: N/A generally, but yes, firmware can be downloaded and flashed via USB key in recovery mode. Specifically, can it self-update within the same firmware version, but update when there is a major new firmware release? You can configure the NAS to self-update from version 5.1 to 5.2 to 5.3, but not to automatically update to version 6.Q: Does the vendor document the changes in each firmware update? A: Yes Q: Can you tell what version of the firmware is now running? A: Users can turn off updates by opting out of cloud services Q: Can you backup the router settings to a file? Q: In a mesh, what happens if one device gets new firmware but another device does not?We have dashboards so we can monitor progress of the firmware releases, which is done in carefully controlled phases. As of mid-April 2017 Google does not seem to have a single web page with a history of firmware releases. I could not tell, immediately, if this was true or not. Firmware revision can be noted per mesh node via the app. Q: Can you be notified of firmware updates beforehand? Updates are done carefully in a phased rollout to ensure no regressions.Q: If you are notified beforehand, can you schedule the firmware installation and the necessary reboots it entails? Q: If you do nothing, how quickly will newly released firmware be installed?As of early May 2017, I was able to answer some of these questions myself. My observations are here 7 mistakes Google made updating my Google Wifi router.In June 2017, a Google Wifi router had been powered off for a couple weeks.
Borrowing from the Security Checklist page, below is my list of things to look for in determining if a self-updating router is doing a good job of self-updating.This is a huge contrast to the much slower rollout used by eero.In August 2017, I setup three new Google Wifi hockey pucks. NOTE: The information below was provided by someone who works for Linksys in February 2017.If its a multi-device mesh router/system, then the question applies to each device. Pretty much any router can do this, but with auto-updating I wonder if that feature still exists. Q: In a mesh system involving multiple devices, do all the devices update their firmware at same time? Can the system run if the three devices are not on the exact same firmware release?A: It is a managed rollout where all nodes are updated during the same session.A: N/A Q: Even if you are not notified of available updates, can you set a schedule for when installation/reboots are allowed? A: Reboots are auto-scheduled within 24 hours and when the systems are idle. Q: Can you force the router to update to newly available firmware, or do you have to wait for its regular check-in? Eero promises to install new firmware "within a few weeks" A: We release new firmware every six weeks. Q: When the router phones home looking for updates does it do so securely with TLS?
