Re : Connexion intermittente : Realtek Semiconductor Co., Ltd. RTL8111/8168
Désolé je n'ai pas de solution propre à te proposer (je suis de passage car je suis au taff ^^)
Mais je te propose de créer un script qui va checker ta connexion et lancer tes deux premières commandes si tu n'a plus de connexion (un ping par exemple).
Je te le déconseille car ça va te bouffer des ressources pour rien et que ça ne résoudra pas le problème, mais actuellement je ne peux que te proposer çà.
Je repasserai ce soir

Merci, saurais-tu comment faire pour tester qu'un ping n'aboutit pas en bash ?
