I have checked for forms about the issue that is sometimes wifi will not show up from within networkmanager and it is stable on Linux here is reverent parts of dmesg
but it spits it out multiple times
Code:
ath0: ath_rate_tx_complete: ts_rate=27 ts_finaltsi=0, final_rix=0
ath0: bad series0 hwrate 0x1b, tries 1 ts_status 0x0
