Upgraded NasNavigator to 2.34 - now on front page of web access I'm being informed that new firmware is available. The link takes me to maintenance which has a note about 1.43 - click on check for update tells me that a new version of firmware is available - but no sign of 1.43 on the Buffalo Support web site yet.
Andstyles - I suggest that you try attaching Linkstation with ethernet cable to prove it works ok - Does for me
However, if it does, when you attach the Linkstation back to your network there are problems with IP addressing. So shutdown restart Linkstation, Router and NasNavigator and maybe the PC you attached by ethernet cable and Linkstation should appear again on the network, albe it with a solid amber light. Good Luck
I assume at sometime 1.43 will appear on the Buffalo site
