Ok, I found this, apparently there was (or is) a bug with the WDTV Live, which has been reported as having been carried over to the HUB.
This may work or may not, but the fix that some have reported as working is to take a blank USB thumbdrive then rebooting the HUB and for some reason the shares magicaly reappear.
Don’t ask me why this works, as that I have never had that problem, and apparently no one who has used this fix knows either. But it wouldn’t hurt to try.
If that doesn’t work, you can try a factory reset. Take a straighted paper clip, & push the reset button on the bottom. You want lose any data on the HDD, so don’t worry about that, it will just reset the HUB back to factory defaults & may clear anything in the network settings that maybe causing you not to be able to connect.
Also, the reason for assigning a Static IP, is because it is more reliable. Think of it like this, what you have now is a dynamic IP, which is sort of like trying to get your mail while living in an RV, you may not get it because your address may change. With a static IP, it’s like getting your mail at your house, (you may still not get it), but your address is always the same, so you are more likely to get your mail. Just make sure that if you assign a Static IP, that you chose one that is not being used by another device on your network.
Something else you can do is to check & make sure that your that your gateway, subnet mask & DNS are right. Go to your HUB and select Setup / Network Settings / Network Setup, then write down the numbers of your Subnet Mask, Gateway & DNS. Then go to your PC, click on the Start menu, then Run & in the run box type in “cmd.exe”, without the ". When the command prompt comes up, type “ipconfig /all”, withouth the " (also there is a space between “ipconfig” and “/all”). Then check to make sure that the numbers for the Subnet Mask, Gateway & DNS from the HUB corrospond to the number next to Subnet Mask, Default Gateway & DNS Server on your PC. They should, but it won’t hurt to check just to be sure.
