ReadyNAS Duo Copying is slow and gives error 0x8007003B

[dashffkjdgfaso]

I can't copy anything or use my ReadyNAS duo while connected to our router - it is incredibly slow (10's of KB) at the best of times and simply errors out most of the time.

If I disconnect the router it works perfectly - but no intrenet...

I've checked the MTU size, and piniging packets etc. and that seems fine, Jumbo frames are disabled on my computer.

How do I go about troubleshooting the router/switches?

Current configuration is Edge router->TP-Link switch->netgear switch which goes to both my computer and the ReadyNAS (it was originally setup without the netgear switch with the same problem).

Thanks for your help, I've fixed the problem though.

It was a network driver issue on my computer and the NAS started working after uninstalling and reinstalling.

Did you have any ports forwarded to your NAS?

Do you have a backup of your data on the NAS?

Can you send me your logs (see the Sending Logs link in my sig)?
