Nighthawk RAX80 replaced a Nighthawk R8500. Cable modem is the CM1000. Provider is Cox gigablast at 1 gb/s down and 35 mb/s up. Setup is plain vanilla with no QOS. Internal speedtest measures 925 mb/s down and 35 mb/s up so the connection is good. With wireless turned off and only one computer directly connected to any ethernet port, speedtest site (on the computer) measures 470 mb/s down and 35 mb/s up. Tried connecting computer directly to the cable modem and measured 950 mb/s down and 35 mb/s up. There is definitely a problem with the RAX80 internal gigabit switch. Performance is half of the rated speed. Hardware? Firmware? Has anyone else seen this? Suggestions most welcome.
Follow up - I decided to return the RAX80. I don't have enough time to be a beta ( or alpha? ) test particpant. I configured an Orbi in place of the RAX80 and tested the Orbi at 950 mb/s down ( wired ) vs 470 mb/s down ( wired ) for the RAX80. Clearly the RAX80 internal gigabit switch has issues which should have been caught before first customer ship.
