Slow Gigabit Speeds - only getting 115Mbps-120 Mbps

[acwong]

Just upgraded to the gigabit and the fastest download speed that I am getting is 115Mbps-120 Mbps.  Have restarted and reset the modem many times with no results.  The modem that I am using is the Motorola MB8600.  Anyone else experiencing this issue? Or have a resolution for this?  Thanks!

I am but am using Xfinity XB7. Wired is great but wifi is trash. Even standing next to the XB7 using my phone to speed test I get 100ish MBS.
I am beginning to think it’s a wifi6 ( ax) issue.
