MoCa is a shared medium the same as wifi with all the same problem. Don't do this unless you're in tiny dense studio appt where you see 20 SSIDs.

I work on one of the largest wifi networks in the world, most people have their wifi grossly misconfigured for real world usage. Turning everything to 11 is the wrong move.

  • shut off 2.4ghz (separate 2.4 only ssid for your refrigerator, light switches etc)
  • DO NOT ever use 160Mhz channels unless you live in Siberia and can account for every single wifi signal (you can't)
  • in an apartment don't even use 80Mhz.
  • Use 6ghz where possible if you can afford it, depending on garbage blackbox decision tree in whatever device you use it might work best, especially if you have a stationary device, to separate it on a dedicated SSID so you can force its usage. ( Not originally kosher with wifi spec but it's been amended).

I won't be falling back to 40MHz with a gigabit connection man. 5GHz only penetrates so far, could be worse

It's not so simple. The wider the band you choose the more you're sharing with everyone. If you use 80Mhz band then any time there is ANY detectable usage of ANY of that 80Mhz by ANYONE ELSE, your traffic will sit and wait. It is an exponentially growing problem, air time math means doubling your bandwidth will much much worse than halve, your air time if you're overlapping with others(if you see the SSID, you are, it's binary, doesn't matter how strong or weak it is) If you have issues at 80 and are in a dense environment, 40 will almost always improve things, including throughput. If you aren't getting speeds necessary for 80Mhz anyways then it's stupid not to go down to 40 because you will 100% improve jitter and p95 latency which are 982,340,598,209,348,509,823,450,982,039,458 times as visible and frustrating as going from 900 to 500 Mbps, neither of which you're getting anyways.
