Connection speed drops from 1 Gbps to 10 Mbps (Vista 64)
- by Kevin Hakanson
I recently got a Windows Home Server (HP MediaSmart Server EX490) setup so I could do backups and other things. However, I am having trouble on my Vista 64 PC. The backup will be making great progress, then it will just slow down. At one point, I noticed the lights on my Netgear GS105 indicated it was not using a 1000 Mbps connection, but a 10 Mbps one. I checked the Status of Local Area Connection (Intel(R) 82567V-2 Gigabit Network Connection) and that also showed the same slow speed. This has happened several times in the last couple days.
When I disabled the network device, and then enabled it, it established the 1 Gpbs connection again. However, some of the times the Sent Bytes Activity on the Status windows indicate that the data flow is still slow (100 to 1000 bytes every couple seconds). Obviously, at this rate I could backup faster to floppy disk. :)
My question is how to diagnose and fix this problem. When I look at the Administrative Events, I do a Errors:
Bonjour Service 456: ERROR: read_msg errno 10054 (An existing connection was forcibly closed by the remote host.)
And a Warning:
e1yexpress Intel(R) 82567V-2 Gigabit Network Connection Link has been disconnected.
I am suspicious there is some power saving mode. I found a post suggesting System Idle Power Saver(SIPS) may be the issue. I am going to try that, but looking for other suggestions or diagnostic advice. I have several new items in this configuration: server, client software, switch and cat6 cables.
