MikroTik RouterOS MMIPS Firmware 6.40 RC 36 Description

What's new in 6.40rc36:

- Important note!!! Backup before upgrade!
- RouterOS v6.40rc36 contains new bridge implementation that supports hardware offloading (hw-offload).
- This update will convert all interface "master-port" configuration into new bridge configuration, and eliminate "master-port" option as such.
- Bridge will handle all Layer2 forwarding and the use of switch-chip (hw-offload) will be automatically turned on based on appropriate conditions.
- The rest of RouterOS Switch specific configuration remains untouched in usual menus for now.
- Please, note that downgrading to previous RouterOS versions will not restore "master-port" configuration, so use backups to restore configuration on downgrade.

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.

  It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.
