The ps4's in question use a figure of 8 power lead only. No adapters.
Interesting, but the PS4 downstairs is NAT 2 with zero issues on fortnite. The internet is definitely worse on fortnite as it lags like mad, often kicks you out to the main menu, whereas other games will randomly lag. Yes I use IPTV, I didn't turn on IGMP as not sure what it is.
I knew it...Your network issue is related in IGMP(IGMP Snooping). You have to turn it on and configure it for IPTV and Surveillance Camera. It depends on your ISP. First check your ISP and then configure it. There is no exception unless you don't use WiFi.
