Title: Host connection lost : One possible cause !
Post by: save on June 23, 2014, 01:53:53 PM

Since I changed motherboard and Cpu, I've been plagued by host connection lost. (asus z97 )
I tried to change things methodical by changing one thing every time I lost connection.


Probable cause was the offload segmenting for UDP, I disabled that feature, and have had no lost connection since then.

might be something simple. try an older Lan driver for your particular motherboard. asus usually has several versions.
the latest is not always the best.

It might also be his router not being able to handle the traffic. IIRC udp offloading adds checksumming to the UDP traffic so that the router has to convert the packages before they're sent to WAN and if the router doesn't like this it will reject the packages.

I'm on 100/100 megabit fibre connected to the ISP's switch (upgradeable to 1gb/1gb)
I work as a network specialist, I have both  tools and equipment to test things out.
I even brought home a bad-ass Cisco firewall (Cisco ASA 5555-X) to do packet inspection, and to rule out my firewall/router as the cause or not.

It's very true new releases of firmware/software often run into trouble,  in this case I tried two different version of the intel firmware, and they all behaved the same way.

I used to have one disconnect ever 15-20 minutes, now I have been playing almost a week every night, with only one disconnect.

I remember on my old I-7 930, I set affinity to one core, and set Aces High permanently to "above average" in both I/O and CPU, using a free software.

Yeah I remember you are a network specialist :) Disabling the offloading is fine if you have CPU to spare as you seem to do. From the limited research I did, there seems to be some problematic driver combinations that won't play nice with udp offloading.
