Could the update to W10 have changed the connection settings?
How have you been achieving this in LR5 e.g. is the wifi connection via the Canon EOS utility and you are then using auto-import to bring the images into Lightroom?
If so have you checked EOS utility to re-establish a camera connection?
Thanks, to answer your questions - the connection settings have not changed and the connection is via the 6D to my router. If you use the EOS utility LR will not connect so you have to quit the EOS utility, then connect to LR 5. This is when connection is made, alas not with LR 6
does not recognize the Canon 6D camera
Explain "does not recognize". Exactly what do you see (or don't you see). Please provide lots of details. If there is an error message, please quote the complete exact word-for-word error message.
Sorry, misleading terminology, within the Lightroom 6 tethering capture - 'No camera detected'
