I've read that Archer C7 v2 has 3 internal antennas (2.4ghz) and 3 external antennas (5ghz).
What would happen if I change those 3 external antennas (5ghz) and put 3 9dbi dual antennas (2.4+5ghz)?? Will I damage the antennas? Will I damage the router?
...in other words, what happens if I passes a 5ghz signal over a dual band antenna? Will it work?
Thanks in advance and sorry for my bad english
