Based on a second generation Broadcom chipset, the Archer C9 AC1900 router shares many characteristics with the C8 which we have reviewed previously, including elements of design. The router takes quite little space on the table and is ventilated properly thanks to the grill located in the back. We again have two USB ports available for data transfer or for connecting printers; in our tests, the USB 3.0 transfer speeds seem to be quite improved, but it won’t be able to match low-end NAS capabilities yet.
