Actually, yes, it would! Because with the L14 we very intentionally wired not just USB and PCIe to the WiFi M.2 slot but also a UART and drumroll SDIO!
But the RS9116 does not have better performance than the ATH9k.
I am evaluating another chipset but this will still take some time. But if that works we will create a new M.2 card which embeds the firmware and this chipset and these cards will then work in the L5 and the laptops and support everything we want, also 802.11ac and BT5. But again, this will still take some time and a lot of effort and money
