As time of writing the newest RouterOS (ROS) stable was 7.9.2 but it was upgraded to 7.10.

AP configuration (CAP)

  1. Unbox your fresh devices
  2. Reset configuration to none (WARNING, you need winbox to connect via MAC after this operation! No IP is set after this to connect via web GUI aka WebFig)
    1. When you connect via winbox just click “Remove configuration” in popup which shows after you connect to winbox for fresh device
    2. After config removal you need to login without password using username admin as usual
  3. Upgrade them to latest version of Mikrotik RouterOS
    1. Download latest main and extra package for arm64 from https://mikrotik.com/download
    2. Unpack extra packages zip file
    3. Upload main unzipped .npk package file with RouterOS like routeros-7.10-arm64.npk and wifiwave2 package like wifiwave2-7.10-arm64.npk to “Files” to main empty directory via WinBox
    4. Reboot device from System → Reboot
  4. Execute/import following config or set it via winbox GUI

As you can see there is nothing special in configuration.The most important part is LAN interface list which creates bridge1.This bridge will be used both for communication with CAPSMAN (other device) and will allow wired network connect with wireless network together.As a bonus and to ease management I setup router IP via DHCP client to access WebFig.

ou can use same config for each AP you have to install, just remember to change system identity part to give unique name to each device.

Change WIFINAMEHERE to something more personal for you.Make sure that your wifi1 is 5GHz and wifi2 is 2GHz. If not, just rename it before applying config.
