Archer AX11000 poor wifi when going upstairs
Hello
I just bought the Archer AX11000 last week at Costco. In our home, we have a family level, a basement and an upstairs. The router is in the center of the house
on the family level connected via CAT 6 ethernet to 1gb cable modem. I get 960-970mb with ethernet to the cable modem. I get about 890-930mb when I
plug in directly to the AX11000 with ethernet. Internet speed test is showing 770 Mpbs download.
As for Wireless: When I'm 6 feet away, 5ghz gives me 334 Mbps download, 2.4ghz gives me 47 Mbps download. I don't have high speed upload.
Walking upstairs one flight of stairs (download speeds): 44 Mbps 5ghz, 42 2.4ghz
I am using today's firmware update: 1.1.1 Build 20200716 rel.84595(5553)
I don't have OFDMA or Smart Connect enabled. HomeCare QoS I have download set to 1000 Mbps for all online activities.
Has anyone else experienced extremely poor wireless reception when moving up just one flight of stairs? If so, what have you done to fix it? I'm ready to return this.
