Suivez le guide \u00e9tape par \u00e9tape de Wifi.se et commencez par les v\u00e9rifications les plus simples. Contr\u00f4lez l\u2019\u00e9tat du service, les donn\u00e9es et les bons r\u00e9glages avant de passer \u00e0 un d\u00e9pannage plus pouss\u00e9.<\/p>\n

Comment trouver la cause d\u2019une connexion lente<\/h3>\n
    \n
  1. Essayez un autre emplacement, de pr\u00e9f\u00e9rence plus en hauteur et plus pr\u00e8s d\u2019une fen\u00eatre.<\/li>\n
  2. Faites plusieurs tests de d\u00e9bit \u00e0 diff\u00e9rents moments de la journ\u00e9e.<\/li>\n
  3. V\u00e9rifiez si le r\u00e9sultat change entre la 4G et la 5G ou, en itin\u00e9rance, entre diff\u00e9rents r\u00e9seaux.<\/li>\n
  4. Testez pr\u00e8s du routeur pour ne pas confondre un Wi-Fi faible avec un signal mobile faible.<\/li>\n<\/ol>\n
    \n

    Testez avant de modifier les r\u00e9glages<\/h3>\n
      \n
    1. Placez le routeur dans un endroit plus d\u00e9gag\u00e9, de pr\u00e9f\u00e9rence en hauteur et pr\u00e8s d\u2019une fen\u00eatre.<\/li>\n
    2. Faites plusieurs tests de d\u00e9bit \u00e0 diff\u00e9rents moments de la journ\u00e9e.<\/li>\n
    3. Comparez le mode 4G\/5G Auto avec un autre mode r\u00e9seau si votre routeur le permet.<\/li>\n
    4. V\u00e9rifiez si le probl\u00e8me concerne tous les appareils ou seulement, par exemple, le t\u00e9l\u00e9viseur.<\/li>\n<\/ol>\n

      Si le probl\u00e8me survient surtout le soir, la forte charge sur le r\u00e9seau mobile peut jouer un r\u00f4le important.<\/p>\n

      Pourquoi cela aide<\/h3>\n

      Lors d\u2019un d\u00e9pannage, il est important de d\u00e9terminer d\u2019abord si le probl\u00e8me vient de la SIM\/eSIM, du r\u00e9seau mobile, du routeur ou de la connexion Wi-Fi elle-m\u00eame. Ne changez qu\u2019une chose \u00e0 la fois et testez \u00e0 nouveau apr\u00e8s chaque \u00e9tape. Il est alors beaucoup plus facile de voir quelle \u00e9tape r\u00e9sout vraiment le probl\u00e8me.<\/p>\n<\/div>\n
