    Keep losing wireless

    I have 2 months since I finally made Ubuntu my primary OS, everything
    works perfect. I'm using ndiswrapper to make wireless work and
    everything works. But somehow, everyday, I lose my wireless internet
    connection after some hours (sometimes minutes) of working, it looks
    like I'm connected but I'm not, I kill X but it just won't restart, the
    only choice is to restart the os.

    This is not the only problem, after I lose wireless, I can't open any program at all, if I kill X, I can login but can't run any command, the only choice is to restart. Because of this, I can't tell you if I can ping to the router.

    When it's restarting, Ubuntu just can't stop avahi-daemon, so I thought
    that was causing the problem so I just stop loading it at boot, but the
    problem remains.

    Sometimes after I kill X, I get the following error:

    [2815.287188] CIFS vfs: error 0xffffff90 on cifs_get_inode_info in lookup of /www

    The problem is that I have no idea on how to identify the source and
    because of that, I don't know where or what to look for, so Google won't
    be of any help.


    I could really use some help here because this is annoying.

    Thanks in advance

    If you try running a program in the terminal after the wireless goes, does it give any errors?
    If I'm not being clear enough or giving you enough information, just ask

    "But woe to him who is alone when he falls, for he has no one to help him up."

    Thanks for the reply..

    I can't run any program in terminal after I lose wireless, can't even open terminal, but when it's open and I loose wireless I get no errors at all, just can't run any command, if I type:

    ifconfig or ping something, it just waits forever to execute and it does nothing

    Are you doing anything like mounting network shares?

    Yes I do mount a directory automatically at boot, could that be the problem?

    This is the network share that I mount, I do it with this line in /etc/fstab:


    Code:
    //server/public /media/public cifs credentials=/root/.smbcredentials,iocharset=utf8,file_mode=0777,dir_mode=0777 0 0

    I have noticed before that my NFS shares can cause problems. Sometimes if something happens to the network, Nautilus will stop responding, and I guess the system could, too.
    I think it's worth a try to comment that out and see if the problem still occurs.
    If I'm not being clear enough or giving you enough information, just ask

    Re: Keep losing wireless

    Unfortunately, that's something I can't do because I work a lot in that network share.

    Is there any other way I could mount that share?

    Thanks

    You wouldn't have to do it permanently, just to see if that's the problem.
    I guess you could mount it through the Connect to Server on the menu, but I'd like to see if that's really what's causing the problems first.
    If I'm not being clear enough or giving you enough information, just ask

    I'll do it and let you know, since the error just happens and it's not like "if I do this I get the error", I guess I'll just have to wait..
