    Strange wireless problem


    I posted this question to the Linux Mint forum, but I really have to get my internet working so I thought I'd see if anybody here has any suggestions. When I boot into Mint my internet randomly doesn't work most of the time. Somebody suggested that I download a new driver for my wireless device but I am having trouble doing that. Here is the original post. All the details are in there, and the last post is what I am stuck on.

    Did you try doing an update? It would help if you could post what you get from the commands ifconfig, iwconfig, and rfkill list.

    No. I haven't been able to get any internet connectivity at all the past 2 days. Is it possible that trying to patch the driver screwed things up? If so, is there a way to recover Mint to what it was?

    I don't have an internet connection to do an update. Here is the data you asked about.

    Rather than invoking init scripts through /etc/init.d, use the service(8)
    utility, e.g. service smbd reload
    
    Since the script you are attempting to invoke has been converted to an
    Upstart job, you may also use the reload(8) utility, e.g. reload smbd

    Another update. I was able to patch last night, and one of the things patched were my drivers. The internet worked until I went to bed. This morning, it appeared to be working for a bit before it stopped suddenly.

    It continued to insist that I was connected to my router, which is new. I pinged my router, and the packets that were returned were returned quickly, but I had 84% packet loss. I tried opening my browser, couldn't connect to a website, pinged my router again, and 0 packets were returned.

    I just booted into mint again. Back to the status quo. Can't connect to my router. Still works 100% fine on Windows so it's not a hardware issue.

    Mint 15 is still in Beta I guess. I see a lot of wireless bugs at the mint forum for Mint 15 but posters say previous version worked OK, though why buggy I don't know. I figure the newer kernel in Mint 15 should be better than what I am running.
