Wired range extension between Archer C6 V4 and Archer C6 v2
I have an old Archer C6 v2 and I have recently bought an Archer C6 v4. Since I have a large space I want to use the old C6 v2 as a range extender.
In my current condition, the wireless extension from the root C6 v4 does not have a good throughput from the C6 v2, but with a wired connection, I get as good a throughput as the new one.
I know the old C6 v2 does not have Easy Mesh support but I want to use the same SSID for a seamless connection between the two C6s, that too with wired connection. Can I do that? If not then what best of an alternative do I have?
