Hello, @christophe , one more thing I need you to try are the steps that I’ve provided in this reply: RUT241 udhcp renew doesn't work - #4 by MatasR
I need you to try running these steps, and if you run into any difficulties, don’t heistate to ask for help or guidance.
If the solution does not work, please reply to me and we’ll continue our conversation privately so I can investigate this further.
Thank you,
M.
