Synology RT1900ac Router Firmware 1.0.3-6022

SRM is the operating system of RT1900ac. The update includes the latest features and enhancements.

Fixes:

- Added the "TCP/UDP" option to Port Forwarding to set TCP and UDP rules at the same time.
- Allows setting the DHCP range for guest networks.
- Re-defined schedule behavior in Parental Control: When Internet access is blocked on a device, you can still use this device to access SRM and other devices in the local network.
- Re-defined “banned” in Traffic Control: When a device is banned, you cannot use this device to access the Internet or SRM, but you can still access other devices in the local network.
- UPnP rules will remain after an SRM reboot.
- Enhanced SRM security (CVE-2015-7547, CVE-2015-3197 CVE-2015-5621, CVE-2016-0777, CVE-2016-0778).
- Fixed an issue where SRM could not find DNS servers when PPPoE was selected as the connection type after a soft reset of the Synology Router (i.e., pressing the reset button for four seconds).
- Minor bug fixes.

About Router Firmware:

Before you consider downloading this firmware, go to the system information page of the router and make sure that the currently installed version isn’t either newer or matching this release.

Due to the large variety of router models and different methods for upgrading the device, it is highly recommended that you read and, above all, understand the installation steps before you apply the new firmware, even if you are a power user.

In theory, these steps shouldn’t be much of a hassle for anyone, because manufacturers try to make them as easy as possible, even if they don’t always succeed. Basically, you must upload the new firmware to the router through its administration page and allow it to upgrade.

If you install a new version, you can expect increased security levels, different vulnerability issues to be resolved, improved overall performance and transfer speeds, enhanced compatibility with other devices, added support for newly developed technologies, as well as several other changes.

If you’re looking for certain safety measures, remember that it would be best if you perform the upload using an Ethernet cable rather than a wireless connection, which can be interrupted easily. Also, make sure you don’t power off the router or use its buttons during the installation, if you wish avoid any malfunctions.

If this firmware meets your current needs, get the desired version and apply it to your router unit; if not, check with our website as often as possible so that you don’t miss the update that will improve your device.
