Is it possible to swap out the stock Marvell 88W8864 wifi card for something that uses the ath9k driver?
According to Librecmc, it should be possible, but I'm having trouble tracking down info on an appropriate card I could swap in there.
Just looking at the card that's already in there, I'm somewhat doubtful that a typical mpci-e card for a laptop would fit but I've been wrong before.

Does anyone have any info about how to do a mod like this?
Thanks.

I admire your creativity, but far better to paint another model router blue.

What’s the best dd-wrt router to buy in 2021?

ath9k is the Atheros IEEE 802.11n driver
so not for modern AC cards

and good AC cards might not fit through the heatsink

and even if you find suitable cards you will need a custom firmware for the router

I'll lay my cards on the table. My objective is to use this device with librecmc. According to the link I posted, you have to change the wifi module to accomplish this. So far, I haven't had much luck tracking down any info specific to librecmc regarding how to do this. Since the issue of changing out the wifi module isn't itself about librecmc, I decided I would ask around elsewhere and see if anyone might have any info about how to do this.
I want a router that's as libre as possible while still being reasonably powerful. Using an ath9k card is a must for me.

No, not at all. The question I'm asking has nothing to do with librecmc. It's a hardware question, not a firmware question. No need to be so trigger happy.

The point is someone attempted replacement but that person w/ ath9k module experience is not here.

I see various forms of communication listed on contact page so these are your best possible solutions.
