I did some tweaks to the router. Nothing so drastic like booting a custom firmware, but I did change the channels, turned off QoS. Much improved. My daughter's laptop, which was getting maybe 1 bar of signal strength on the 5ghz network is getting a full signal and 150 MB down. I pay for 200. The 2.4 Ghz band gets me about 50MB down in the room with the router so I may be getting some interference on that.
Overall, pretty stoked, but a little confused on one thing. My Insignia Roku tv in my kid's bedroom using the netflix app speed test has it at about 25MB down, while her laptop, as I mentioned is at 150MB. I wonder if the radio in the tv is weak or if there is a placement issue. I may put another Mesh device in her room to see if that increases the DL speed, but it says it has a full signal.
