Hello fellow Magickians,
Lately I've been hosting a couple of games and suffered a lot of client disconnects while hosting a game.
Clients would disconnect after 30 seconds to 2 minutes all with the standard disconnect error message.
By this point I already reinstalled the game/steam, drivers, etc, etc but this didn't solve the problem.
So I started packet sniffing my network and discovered a lot of TCP retransmissions were happening during the game.
What worked for me was disabling Jumbo Frames on my NIC and I could host games for hours without issues.
So if you have disconnect issues it might be worthwhile to check if you have enabled Jumbo Frames.
Fixing it:
The somewhat more permanent way:
If you don't need Jumbo Frames.
Go to >>Control Panel\Network and Internet\Network Connections and open the properties of your Network card then select Configure > Advanced tab \
and you'll find a setting called Jumbo Frames you can disable this setting. (or lower the value to a setting that works for you)
The temporary way:
E.g. adjust the MTU value before running the the game.
Run the commands below from a administrative CMD line!
If you have Jumbo Frames enabled you most likely find a MTU higher than 1500
To show your MTU size run the following command:
netsh interface ipv4 show subinterfaces
(Your output might differ)
MTU MediaSenseState Bytes In Bytes Out Interface
------ --------------- --------- --------- -------------
1500 5 0 0 Local Area Connection
9198 1 0 0 Local Area Connection 2 <- in my case #2
To temporary change the MTU settings run the following command:
netsh interface ipv4 set subinterface "Local Area Connection 2" mtu=1500
And after playing the game you could change the MTU back to the previous value of 9198 or whatever your previous setting was.
Hope this helps.
