"Network link down"

Since i don’t get any repply from WD via support, i’ll try here instead!?

How do i resolve the issue with this error; “Network link down - The network link is down or has become intermittent. Please check your network connection.”

My network runs just fine, and this error happened after latest firmware upgrade.

Please advice?

Look in the diagnostic logs.  See if there’s any messages in there indicating a network issue.

Just created a system report, and saved it to my drive.

Tons of files in there, but as a non-techie, i have no idea what to look after?

Look in the “Log” folder for the file named “messages”.

look in that file for any instance of the word “eth0”

Does this make any sence?

You might be confused by how the alert works. If you don’t clear it, it will come back up the next time you look at the Dashboard. To clear the alert, click the checkbox and the “X” at the upper right of the alert. I might be that you think it is always having this issue, when it was a one time event.

Very “clever” firmware indeed!

My bad!

Thanks for the heads up there Tony.

I’ll be back if the alert shows up again.

Cheerz.

Tony is correct, but either way, both the notification and your log files indicate that your network connection was dropped.

It might have been due to a reboot, but that’s hard to tell unless you remember what time the reboot occurred…

Found out that transfer speed get’s VERY slow(250-300kbit) over time if connected through a switch(even if all network is at full gigabit), but i can prevent this issue with direct connection to router.

Remains to be seen if the “network link down” issue returns this way?

Eeek.   That’s not good…   The speed thru an external switch should be unaffected compared to the inbuilt-switch of the router. …  assuming, of course, that all else remains the same (no cable faults, no switch problems, no configuration problems, etc.)

I have two switches between my PCs and my NAS, and I can still get 220-250 megabits per second from it…
