It's been about 3 weeks since we've installed the Livebox router from Orange and since then I've have experienced some problems while connecting to some servers :
Switch can't connect to Nintendo network
Playstation can't connect to PS Network
Can't go on some websites for example websites that finishes with .com or .net (I couldnt connect to reddit or Pinterest for a while)
Note that some things were still accessible like YouTube and WhatsApp, and that changing my DNS to cloudflare's would sometimes help and sometimes rebooting the router solves the problem for a 1-2 hours but then it doesn't work again
Also while trying to solve the problem on my router's configuration settings I've seen that IPv4 is unconfigured and I can't seemingly do anything about that
I already called the Orange support yesterday but they said they couldn't do anything because they couldn't access their website
Any help would be greatly appreciated !
