Thread: 11.10/12.04 no wireless connection


i had ubuntu 11.10 updates, have 12.04, daily build.

connection wireless router (huawei hg 655b) impossible.
deleted connection, recreated , edited new 1 (i have set mtu 1500 , disable ipv6 otherwise ap freeze), changed security (wep, wpa, wpa2) , encryption (aes , tkip), no luck.
mean time ap used windows, android , symbian devices.

syslog (see below) suggested dhcp timeout.
reconfigured ap , interface static acces. after network-manager report connection ping ap has no reply (strange)!

installed 12.04 daily build, tried wicd no luck
try change network adapter in mean time suggestion appreciated.
