The method that I follow (and invariably works) is:
- Flash all routers to the same version of the firmware. Today, I would be hard-pressed to not use RMerlin 386.3 Beta 1.
- Reset all to factory defaults, using the appropriate WPS method for the router in question. After they have been reset, turn them off (physically unplug the power plug from the router) and do not turn them on until you're ready to connect them as nodes (see below).
- On the main router, do a minimal and manual configuration to secure the router and connect to your ISP. Use the suggested 'best practice' defaults from the links below. Do not insert any USB devices into the router at this point.
- Make sure that the USB drive you intend to use for amtm and the swap file is FIRST formatted as NTFS on a PC. Do not insert a previously used amtm USB drive into the router.
- Fully set up all scripts you want to use via amtm (or manually). Be sure to test after installing every script that all is working as expected. Be sure to reboot the router and then test once again.
- With the above complete and fully tested and verified working, you can now add your AiMesh v2.0 nodes.
- Add your nodes by powering on the additional router, going into the main router's GUI, and '+ Add AiMesh Node'.
- After the node is added, wait for 5 to 15 minutes before you power the node off and move it to the location you want it in.
- Power it back up and wait until it is stable once more (5 to 15 minutes, depending on the router model).
- Repeat the above steps to add all the nodes to your network.
With all the nodes added, I would reboot the system via the AiMesh, System Settings, System Reboot button via the GUI.
If the network is still not stable, choose a different Control Channel until it is. Be sure you reboot the entire network after each change while testing.
