SRM 1.3.1 is the current operating system of the Synology RT6600ax, WRX560, RT2600ac and MR2200ac routers. Version 1.3.1-9346 Update 5 is the fifth official update released after the first Official Release 1.3.1-9346, and was released yesterday, May 4, 2023. Unfortunately, the new SRM 1.3.1-9346 Update 5 version maintains the outdated PHP 5.5.25 version, an issue that I reported on June 26, 2022, almost 11 months ago. SRM 1.3.1-9346 Update 5 fixes some important issues, but preserves an outdated PHP version. The new update 5 version fixes the issue where Internet connection speed might be slow after Threat Prevention is enabled. Download the new 1.3.1-9346 Update 5 for your router model from the links below, then manually install it.
Log in to your Synology router then go to Control Panel / System / Manual SRM Update. Select and upload the file you have previously downloaded at the beginning of this article. Follow the instructions in the image below.
After you click OK at STEP 1 a new pop up window will appear with the following message: The system cannot be shut down during the update. Do you want to continue? Click Yes. Wait approximatively 2 minutes for the update to be completed. Follow the instructions in the image below.
If everything went well, you should see the new SRM Version 1.3.1-9346 Update 5 correctly installed.
