% ifconfig wlan txpower 10
ifconfig: interface wlan does not exist

with the default of 30:

my ISP's promised 500 Mbps comes trickling down to 25 kbps.

how can we fix that?

Unlikely to get fixed in iwm still with a complete iwlwifi update coming one day but I'll leave this open in case someone wants to do it.

If your problem is speed then your problem is most likely that iwm only does a/b/g and you are on 'g' and I wouldn't be surprised if the spectrum is a bit crowded there?

re iwlwifi, when is "one day"?

how many devices does it take to crowd a network so badly, that bandwidth drops by several orders of magnitude?
