Everytime i dowload something on battle.net (this only happens with this launcher too).
Conjestion control has a flip and causes very high pings on the rest of the network. 200+. Currently as a workaround i have my PC connected to a vpn to download CoD updates etc.
i have 350Mbps coming in and im only able to download at 7MB/s tops when not connected to VPN. 32MB/s when connected to VPN. When connected to VPN i get no further conjestion on the network and everything runs just about as it shoudl.
My setup is a XR1000 connected to an EAX80 Extender which is wired to it. It's not just what is also connected to the extender has a flip it seems to bog down the whole network.
