Which generation router? Do you have a power LED? I would try a factory reset, that's about the only other thing to try. For Gen 2 routers (without reset button) power cycle the router 6 times in a row by unplugging/plugging in the AC power cord to the router. On the last power cycle, give it 5 minutes to boot up. Check your phone settings for the "STARLINK" Wifi network. If it never powers on and you never see the Wifi network, you need a new router.
