RTL8191SU et qualité de connexion
Bonjour,
Je rencontre des problèmes de connectivité avec un dongle Wifi usb avec un chipset
RTL8191SU (Bus 004 Device 003: ID 0bda:8172 Realtek Semiconductor Corp. RTL8191SU 802.11n
WLAN Adapter)...
Il marche pour certains points d'accés (mon smartphone, un routeur 4G ou bien une bbox)
mais pas la Freebox HD (V5)... une fois sur 10 (je n'ai pas fait de stats) la connexion
s'établie avec des grosses variations de débit et des déconnexions...
Même avec FreeWifi, il semble que le DHCP n'a jamais de réponse :

A priori le firmware est à jour avec la dernière version disponible : firmware-realtek 0.44
Je suis avec un noyau 4.0 experimental, mais j'ai essayé avec le noyau de Jessie et ça ne
fonctionne pas mieux !
Est-ce qu'il y a des parametres qui pourrait améliorer les choses ?
