I'm testing with my phone. Previously with Xfinity, I was on a 600/20 plan and got 579/17.7 from my phone. However, I had to factory reset my XT8 and don't remember what changes I made. I'll have to read some old threads haha.So the router isn't an issue (at least when wired).
What device(s) are you using to test with? Standing 'next to the router' isn't going to give you the fastest speeds. Test at least from 10' and further. Ideally, 20' to 30' (line of sight) is best.
Can you use a laptop that is plugged into an AC wall outlet running in Performance mode to see if the speeds are better?
Can a friend bring one of theirs to test this with?
I'm assuming/suspecting that the handheld devices you're using aren't enough hardware for the speeds your network is capable of.
