Gentlemen there appears to be a problem when using the pre-release on an LS as the TCP base. I loaded the PR on both my base and rover, base using a LAN connection checked all the port settings on both receivers, the base always showed 1 connected client when the settings were right, but no corrections were being received.
I then reverted the rover back to Recomended, same results. Reverted base back to Recommended, immediately getting corrections as before.
Then moved the Rover back to pre-release, corrections being received.
So it appears something is off for using the LS as a TCP base...
