Doesn't go above /36Mbps .

Not too unsurprising.  Primary concern currently is to get it stable
before making it go fast.  We can probably look into that early next week.
I'd do right away but I have to be up and out of the house early
tomorrow morning so need to stop for tonight.

Most importantly to me currently:  does it crash still (fw crashes or
panics)?   Does it work longer term reliably?   Also people who get
out or move a lot: does it hold up when roaming (possibly manually)?
These kinds of things.

Lots of health,
