I've had unRAID 4.7 working great for the last few weeks.  After installing a new PSU I can no longer get a network connection.  Have tried multiple cables, some known working with other machines, tried using a static IP and DHCP and no luck.  Here's my hardware and syslog attached.

Antec 900

Biostar TH55 HD

Intel Core i3-550 Clarkdale

Kingston ValueRAM 2GB 240-PIN DDR3 SDRAM DDR3 1333

Corsair Builder Series CX430

6 hard drives - WD/Seagate mix

syslog.txt

from the biostar website his board has a

Realtek RTL8111DL - 10/100/1000 Controller

unraid uses the right driver

but for some reason your eth0 is not detecting an uplink

did you try another port in your router ?

restart router ?

 

 

Well, after trying every combination I could think of I've got it working, turns out for whatever reason when the server was behind a switch (both a Trendnet TEG-S80g and a  DGS-2208) that I couldn't get a connection, if connected straight to my router (Linksys WRT350N) it worked fine.  Still no idea what the problem was and if you have any insight, let me know but I'm just happy it's working and wasn't too much of a pain in the B.  Thanks for your help sacretagent.
