Synology RT6600ax: SRM Version 1.3.1-9316

Synology RT6600ax SRM Version 1.3.1-9316

SRM 1.3.1 is the current operating system of the Synology RT6600ax, RT2600ac, and MR2200ac routers. Version 1.3.1-9316 RC (Release Candidate) was released today June 24, 2022, and one of the major updates to the software is that it now supports compatibility of the mesh Wi-Fi system between the RT6600ax, RT2600ac and MR2200ac. I have already upgraded my environment because the RC version fixes multiple important security vulnerabilities such as Synology-SA-22:09 SRM. Considering there are multiple security fixes in this RC, it’s actually a good idea to update to the RC version before the final version becomes available which can take a bit more time.
