Periodically I get this message, although I can only read the first part and am guessing at the rest. Basically the Pronto will not execute the instruction, nothing happens and I end up resetting the wireless extenders - all is then fine, but it does return from time to time and winds me up.

Set up is two TSU9800s, both used (though not at the same time) but usually just the main one. I have seven RFX9400s in stand alone mode, and when everything works, it all works perfectly.

I have noticed that on one occasion, one of the RFXs had an illuminated 'busy' LED, but the last time it happened that wasn't lit. I took the liberty of swapping that RFX for a spare, but it has happened since without 'busy' LED. Restarting the RFXs always rectifies it.

Any help greatly appreciated!
