Hi,

Sorry to tell you that we only provide English Service for Global users, so we tried to translate your question into English and continue to help you. Wish your understanding.

Have a good day.

For the differences among the three routers, you can refer to the spec or the user manual to get more information and verify which one can satisfy your needs better. FYI, the three routers all have the gigabit ethernet ports, they can handle up to 1000Mbps speed.

Besides, compared to Archer C9/A9, Archer C7 V5 supports onemesh feature. 

May it help and have a nice day.
