I've narrowed down some connection problems (failure to get past initial screens) with MSFS2020 to my Orbi RBR40 router. If I disconnect the router from the Spectrum modem and connect my flight sim PC directly to the modem, all is well. Going back to the default config: modem->RBR40->all connected devices including the sim PC, the sim PC will fail to execute properly (1 of 5 simulator executions actually works). If I reboot the router, it will work for a while, then crap out! I also get a ton of DoS tetxts in the Orbi log...
I've tried numerous settings including setting up a DMZ and disabling DoS protection - nothing made a difference. Getting ready to junk it and go to another vendor.
Any ideas? Yes, the firmware is up-to-date.
