Hi there,

LrOs is not officially[1] built for the C5; if it were, perhaps a
tweak could be made so that LrOs' default packages for this target's
ath10k card were different; see (if LrOs is a direct fork of OpenWrt)
https://github.com/openwrt/openwrt/blob/master/target/linux/ath79/image/generic-tp-link.mk#L55.

Other than recompiling from scratch: you have the kmod-ath10k-ct and
ath10k-firmware-qca988x-ct packages driving your ath10k (QCA9880-BR1A,
probably) radio. These are the default packages for OpenWrt for this
board target. These are the Candelatech variants of the drivers and do
not support mesh mode[2].

To change over to the non-Candelatech packages, you could:

- remove kmod-ath10k-ct and ath10k-firmware-qca988x-ct
- install ath10k-firmware-qca988x and kmod-ath10k (in that order)

.... but I am not that well-versed in LrOs, only OpenWrt. In
particular I notice the package manifests only have wpad-basic and not
e.g. wpad-mesh-wolfssl. Some custom stuff has happened here that
others should speak to.

Best,
