Le NAT devient surtout pertinent pour des usages avanc\u00e9s comme certains jeux, l\u2019acc\u00e8s \u00e0 distance ou la redirection de ports.<\/p>\n<div class=\"wifi-faq-v4\" data-v4-expanded=\"1\">\n<h3>Ne modifiez pas plus que n\u00e9cessaire<\/h3>\n<p>Les r\u00e9glages du routeur comme l\u2019APN, le DNS, le mode r\u00e9seau et le VPN peuvent affecter toute la connexion internet. Modifiez donc un r\u00e9glage \u00e0 la fois et notez la valeur d\u2019origine avant de changer quoi que ce soit. Vous pourrez ainsi facilement revenir en arri\u00e8re si le r\u00e9sultat se d\u00e9grade.<\/p>\n<h3>Si cela ne fonctionne toujours pas<\/h3>\n<p>V\u00e9rifiez l\u2019\u00e9tat du service, puis testez une chose \u00e0 la fois.
