@NotANormalNerd thanks for the pr.

Can you follow the pattern used here?

https://github.com/openwrt/iwinfo/commits/master/devices.txt and squash the 2 commit?

[NotANormalNerd]

I will try to figure out the pattern and squash my commits 😄

Thanks for the quick feedback.

@NotANormalNerd Hmm, In my installed AW7916-NPD, I only detected this one instance :

So there is no "0x14c3 0x7909 0x14c3 0x7909", only "0x14c3 0x7906 0x14c3 0x7906"?.

[NotANormalNerd]

@trippleflux Yes, you are right, I have the same output. My first commit was wrong, typo.

@Ansuel I updated the commit message and squashed the commits. Should be fine now.

[Ansuel]

@NotANormalNerd commit description is still missing.

[trippleflux]

@NotANormalNerd I was just trying to be helpful, because I am not a hardware expert, probably I am just missed something.

OT : For AW7916-NPD for 2,4 GHz, is it true by spec they lock it up at 17 dBm?.

@Ansuel, please pardon my Off topic this time.

[NotANormalNerd]

@trippleflux No you were absolutely right. I am also no hardware expert just trying to contribute my bit to OpenWRT.

For the question about the power output: looking at the shop page of AsiaRF it seems that for 11ac & 11ax at HE40 they seem to have limited it to 17dBm: https://asiarf.com/product/wi-fi-6e-mini-pcie-module/

I am personally still a bit confused about the second onboard chip, since they have a Filogic 630 (MT7916AN) and a Filogic 830 (MT7976DN) onboard for the offloading. But it seems the 830 is doing the physical stuff and the 630 is doing the logical stuff. Either way: great chip.

[trippleflux]

Yes, I think so a great chip, I should read chipset specifications more often.

Reaches 400-700 Mbps download 1,5 meters from it, with openspeedtest with my three tripple-band antenna even not properly aligned and lined up (they are horizontally lined up). Overall satisfied even with locked 17 dBm @ 2.4 GHz.

[NotANormalNerd]

@Ansuel Should be ready now.
