How long have you let it go before checking if IPv6 is enabled?
It could be like back in the day, you had to reboot in a specific order and give the modem time to fully come online before starting the router. Its trying to get IPv6 to early, the modem/ISP isn't providing it, so it times out. Maybe after a specific period of time, it'll recheck.
Or you could simply get a UPS and put the modem/router on it and see if that resolves it.
