Salut,
 
Est-ce qu'il existe un moyen de connecter une antenne supplémentaire à ce modem ?? J'ai un ami qui va le recevoir mais les murs de sa maison son assez épais (vielle ferme rénovée). Bref il veut pouvoir rester connecté dans toutes les pièces et dans le jardin avec son ordi portable.
 
Si y'a pas de connecteur antenne alors comment faire ?? merci pour l'aide. A+

ici tu as des vues du modem

où on voit que les cables d'antennes n'ont pas de prises internes. Donc si tu veux continuer dans ton projet il faut couper les cables et rajouter des prises adaptées, Mais tu n'es pas propriétaire tu modem donc à priori interdit.

        Set the transmit power for A band(0-63).
        -1 - default value

Merci pour les infos. Je me demande si allonger la longueur des cables et augmenter la puissance avec la commande wlctl pourrait suffir finallement (faudra me donner un tuto !). Mais quand même ils sont stupides de refiler un modem sans prise antenne... Ca leur arrive de penser aux gens qui on des grandes maisons ou à plusieurs étages ??
 
 
 
EDIT: Sinon je viens de trouver aussi ce répéteur de signal qui utilise les courants porteurs.

Apparement il disent que ça marche avec nimporte quel modem wifi routeur..

l'inconvénient du CPL c'est la liaison est limitée à 14M si ta synchro est plus élevée tu vas créer u  goulot d'étranglement

Je sais. De toute façon il est pas en zone dégroupée. Il aura seulement du 2Méga. Sinon y'a aussi des repeteur genre Linksys 54G. Le prix : 90 euros au moins. Internet la grosse arnaque...................................

Sinon en courant porteur il y a ça à 85 Mbit/s mais pas donné : Devolo MicroLink dLAN Highspeed
J'ai l'impression qu'ils sont les seuls à cette vitesse pour le moment.

les deux fils d'antennes sont clipsés avec un système de bouton pression un peu comme les piles 9V.
Donc de l'espoir
