Superuser1--
Just want to mention I have Zero problems on any other device including a number of daps including Pioneer, Sony, Activo, etc.. so I don't get why if I am using IPv4 successfully why it would be an issue with R5. The only time I have ever read of anything like this was with an oculus quest on networks that share SSID's ( ithink they mentioned orbi's and some other equipment as well). I also did see it for myself--the quest would flash no internet connection intermittently when network handoff to 5GHz occurred. The only fix when I saw this-about 5 months ago was to set up an access point and pick either 2.4 or 5Ghz or split the bands by telnetting into the router.
