Deco x55 network wireless connection speed drop issue
I recently purchased the Deco X55 for the advertised network wireless connection speed of 3.0 Gbps. I did the auto firmware update to v1.8.0 (just getting this out of the way)
I noticed the advertised wireless connection speeds are not consistent. If I am literally about 12 inches to 2 feet from the router. I do see that my mobile device does get a 1.2 Gbps wireless connection, but as soon as i start to move a little farther the wireless speed drops and at about 4 feet away. That network wireless speed drops to 720 Mbps. I am not sure if this is a setting issue or a firmware issue. How can I ensure that as I move further. The wireless connection speed stays relatively close to the 3 Gbps that is being advertised for the product? Thank you
