Thread: Dell Inspiron N5050 w/ 12.04 LTS & AR9285 has unstable wireless
hello all,
few days ago, i've noticed wireless has stopped working on computer. lasts few hours, survives few on/offs wireless switch (fn + f2), not work when turn on wireless again. wireless icon in top right indicates wireless disabled, , when attempt toggle airplane mode in network manager in settings, message changes "device not ready". in order working again, have dual-boot windows (where isn't working there either when boot up), , disable/reenable device driver in there using device manager. not cold shutdown good.
in bad state right now, connected ethernet internet. infeasible me because school not have wired internet virtually anywhere.
should note installed dansguardian , squid 3 on computer few days ago , did not experience problem before this. can't feel uneasy state of laptop since have fiddle around in windows work. , disconnecting dansguardian , squid did not restore wireless internet, far can tell. i'll have see happens if uninstall them.
have ideas? thank help.
here's output "lspci -v | grep wireless":

edit: bypassing proxies , disabling dansguardian , squid allowed wireless work again (without booting windows) turn off using hardware switch, won't turn on again. still think sort of software problem. don't think dansguardian , squid meddling internet badly.code:3.2.0-40-generic x86_64
edit 2: after fixing broken packages in recovery mode, wireless still won't turn on, , tty terminals being flooded information (which retrieved "dmesg | grep ath"):
