Hello, I've been update my Yealink SIP-W52P and Ğ°fter update I have a problem. My handset always lose connect with the base. The version of base firmware is 25.40.23.3, but by the link the newest is 25.40.0.15.

I can found 25.40.23.3 firmware here but there is also another version for handset (26.40.0.26).

I can't understand what information is up to date.
25.40.23.3 is a custom for our distributor YUK and 25.40.0.15 is the latest version of Yealink neutral version.
You should check the handset version for your base at the same time.
