Just set up my AR-750 CRETA.This unit tethered to my cell phone is the same speed with no loss of speed when using 5G and is impressive. I can get 66Mbps through 5G wireless but only get 26Mbps through wired connection. Is there a way to speed up the wired connection so I can connect this to my router, to replace my cable modem. Thanks.

I am not sure why 5G wifi is faster than Wired.

But 66Mbps tethering is already the very high. Generally I just get 20+mbps when tethering iphone.
