Greetings
So 1. We are not in a 5* but a community of help so the vouvoiement…
2. It’s clear that optimization helps but as I said if you reread the posts it has already been proposed.
3. I wasn’t rude but I find that saying things that mean nothing (wlan ipv6????) serves no purpose other than sowing doubt, creating confusion.
So if the goal is to post for the sake of posting there is Facebook,…
Of course, sorry for offending you.
