How to disable 5GHz wifi w/ 2.4GHz intact

hi

Is there an easier way to disable 5Ghz radio, but to disable that interfaces via UCI and then unload ath10k modules ?

uci set wireless.radio0.disabled='1'
uci commit
rmmod ath10k_pci
rmmod ath10k_core

Saved me some Watts and problems with roaming range....

Unload no, if it's permanent, rmmod them post boot, in rc.local, or create an image without the ath10k packages included, using the online image builder.

If you simply have the 5 GHz unconfigured, is that not enough? Are you sure there is more power consumption?

It is still running albeit w/o config.
rmmod (unload) did make the change in power consumption.
Checked on PoE stats on switch uplink port

I am amazed it made a difference. Perhaps you have a more sensitive tool to measure than I.

Not that much, but if you have more APs and better roaming range w/ 2.4

Found out that this can't be done on

Mode MikroTik hAP ac2
Target Platform ipq40xx/mikrotik

Since there is no separate module for 2.4Ghz.
All are loaded with ath10k.
