Buying a new router solved the problem.
But I must say the linkstation is a piece of **bleep**. No end of troubles with it.
1. When I first used the device I put in two harddrives .. One was empty and another had data and it deleted the contents without confirming with me first. So now Im using disk drill to get my data back
2. Now I only want ot use one hard drive.. It was stuck in raid mode, so I deleted the raid and formatted the hard drive from the web interface. That did nothing!!!!!
3. So I took the hard drive out and formatted it myself.. now the device is in emergency mode.
4. Im trying to get out of emergy mode but it wont let me from a mac apparently
This is a nightmare!!!
The web interface should provide me with options to get rid of the raid and work properly. It also should not assume that you want your disk wiped.
Now the linkstation is a brick!
