So when I work this area the first move is to a wired connection. If the wired connection drops we usually find the game in question has many prior complaints.
There is so much missing detail in your post that I won't start a discussion here. But want to hear all the details since your setup is non-standard. I can't tell what the routers are, how connected and so on.
For example, any over 50 megabit connection and we must use all Gigabit routers. I will not debate this requirement. We lost so much time over the years trying to fix speeds on old sub gigabit routers that we just don't bother if we have an old router in the mix.
There is another question for this which had a similar probelm to mine but it does not help me because that issue was for all PCs, this is only on mine.
Recently I have been gaming and experiencing a lot of packet loss, and disconnects from games, my connection overall is great, i can surf the net, watch videos, streams etc. But on games it all goes downhill I have a 200mbps synchronus connection. I have a main router which connects to a lesser one to enable wi-fi, my PC is connected directly to the main one, had no problems until now, tried to connect my PC to the lesser router to test, still the same problem, connected via Wi-Fi, same issue, I have tested with other PCs and devices to connect to the same routers, Ethernet and Wi-Fi, no issues at all. What can I do? I just checked the game publishers websites for firewall rules but that does not seem to work either. Help please.
Thanks.
