It has been mentioned many times during open beta, that the power management facilities within windows 7 x64 in regards to Lan Power Management affect game connection stability, I was able to recreate this problem myself and advised a dev via IRC, he asked me to post this here for your review,
The power management facilities within Windows 7 x64 cause regular server timeouts when playing STO. It happened around 8 times in the space of an hour when playing during Open Beta. After disabling Power Management on my Lan Card there were 0 disconnection the following hour, I dont know if this is because STO does not require a consistent connection to the shard or not but it seems that after a certain amount of time the card powers down and then STO seems to disconnect.
To fix this as mentioned before i either lowered the power management level in Windows 7 or disabled it completely both options resulted in a fix for the issue.
I havent tested this on a desktop system but both my Windows 7 x64 Ultimate Loaded Notebooks were affected, my Windows XP SP2 notebook did not seem affected regardless of the power management settings.
I don't get why Win7 would power down LAN after such a short time of no network activity with relation only to STO. Never had an issue with that before. What were you doing ingame? How can there even be enough of a communication gap to trigger this?
Turning off my laptop's LAN power management just in case til this is clarified. Thanks.
