Hi Guys hope you can advise me, I have the RT-AX88U router and for a while now the 2.4ghz wifi does not operate when the router is rebooted for any reason, well I've just installed the 386.8 f/w update and it fails to come on at all even after reapeted reboots, I'm not sure whether it's the router or the f/w's could you please advise.
