@anchalsingh Aashish_AS is right. Archer A6 v3 is also being planned to be compatible with EasyMesh according to the EasyMesh Compatibility List, but there is no date.

@sukas Do you still remember what is the previous version? If yes, you can try to roll back to that version and monitor if the connectivity is stable. When you mentioned "lost connection randomly...

@Aashish_AS If you cannot detect the new firmware on the router web, just install it manually by downloading the latest version from the local website and installing it manually. But please be sure...

@Androidami You will need to pay attention to the EasyMesh Compatibility List for any updates.

@Omniman I'm curious about the brand and model of the wireless adapter of the new laptops, are they the same brand and model? How many of them? Do you use Onemesh or Smart Connect on the Archer C6U?...

@Archer3150 Only the listed models support VPN Client.
