Hi I uploaded the 3.4 zip file and after 20 mins the process had not completed. I power cycled and connected using USB, the 3.4 firmware had loaded but presumably not the wifi firmware as it was expecting it to be in directory called "firmware" which did not exist.
I only read upgrade notes quickly, but did not see any requirement to go from prior 3.? version to 3.3 first, should have looked closer.
All working again, just posting to try and put some info in case others make my mistake.
Thanks for fab product and support.
