To put this first, I've already gone through all of the steps the supports pages for the delta-03 error say to do. Port Forwarding done, UPnP enables, rebooting the router & cable modem, I've even done factory resets on the both the router & cable modem and the annoyance of reconfiguration them to work with the home network again (including putting port forwarding back in place). I've also tried putting my PC to be in the router's DMZ to no effect. Tried using googles DNS instead of Sparklight's default ones. I'm hardwired directly to the router. Done DNS flushing as well, also happens whether Comodo internet security's is running or not. Host file didn't effect anything.
The delta-03 disconnections happen while play Division 2 at random intervals. Sometimes 5 minutes in, sometimes 15 minutes, some times 30 minutes of play time before a disconnect. Before some of disconnect I stop being able to do damage to enemies or reload etc. NPC are still able to damage me visually but they don't seem to move correctly, so an empty mini-gun emplacement will start firing like a NPC has just started using it, after which the Delta-03 happens. This seem to be pointing to receiving incoming data but not able to send any. Other times I'm looting stuff then straight to Delta-03.
I've narrowed it down to the router, a netgear R6220, with firmware being up to date accord to netgear support pages. When I bypass router and use my phone's hotspot late a night or directly connect my PC to the cable modem there is no issue and can play fine. But a direct connecting to the modem is not a possibility since the whole house uses the internet, and phones hotspot is flaky during the daytime. The logs for the Router and Modem show no disconnects, refused connections or errors of any kind, except a single time and entry where the router thought Facebook was doing DoS attack. Only Division 2 is effected, no other game or software has an issue, not even other ubisoft games like the original Division, which I can play it hours straight without a single issue.
