January 9, 201115 yr Hi! I suddenly have a connection problem to one of my unraid servers. It was running fine for many months. The server OS loaded properly and I can see all the mounts from the console. But cannot connect to it from another computer. These are the symptoms: -WebGui connection is slow and will only load partial and most of the time will time out, cannot connect to the ip address. -Using Ping to the ip address yielded 75% to 100% failure. -I did all these without success: -Swapped the port on the ethernet switch -Swapped the cable -Swapped network card -Changed from OS v4.6 to V4.56 -Memtest seems ok -Updated Bios and even tried reverting to older version So, the only thing for me to rule out is the motherboard. Is this possible and a common problem? Any other suggestions? Thanks for your help.

Or perhaps not assigned a unique IP address on the LAN? Check in the config/go/network.cfg to see if the HWADDR line has a MAC address. If so, DELETE the HWADDR line, stop the array, and reboot.

January 9, 201115 yr Author Thanks Joe! No wonder you are a Hero here OK your suggestion works (deleting the HWADDR line). Now the webgui is at least apprearing although slightly solwer than normal. When I ping both unraid servers, it is returning some "Request timed put". Even the the good server is not pining right now. Updated: Most of the time ping ok, but some lost packets occassionally. Looks like you are on to something. Should I delete both HWADDR lines from both machines and try again? BTW, both servers have statis IP address.
January 9, 201115 yr Author Now that I can have access to the webgui, I have noticed both my unraid servers have the same MAC address! Is this why I am having network connection? How do I resolve this problem? Thanks again!
January 9, 201115 yr Delete the line from both servers. Turn off both servers and your router. Then turn them all back on.

After deleting the HWADDR line from the network.cfg file on both unraid servers, the network connection is back to normal and works. Ping is 0% loss.
January 9, 201115 yr In general it ist not advised to assign MAC addresses manually. You should always use the buildt in MAC address of the network adapter. Strange things could happen, if you do

Strange things could happen, if you do The MAC address was not changed manually and you cannot change it from the WebGui. I have no idea how it was changed.
January 9, 201115 yr The OS records the mac address in network.cfg. Did this file get copied from your older server to the newer one?
