• Unusual WiFi Disconnects


    At home and at work my WIFI connections have been very stable. However, while traveling on vacation I keep disconnecting dozens of times times an hour. (I have 2 other ASUS based laptops running Mint 17 and HP ProBook running Windows 7 - all of them have no problems with connectivity to same access point).

    I turn off WIFI and turn it back on. Reconnects fine. After a short time it disconnects again.

  • HI,

    From what I can tell the issue is due to a bug in the intel driver causing the firmware to disconnect too quickly when it thinks the router is no longer in range or responding. If there’s any way for you to move closer to the router that will be your best solution (I know thats hard to do when you are in a hotel). Hotel wifi is spotty at best in my experience, I usually try to bring my own LAN cable or ask the front desk if they have one (they usually do not). Here are some links that you can check out with some recommendations that may help but honestly I wouldnt waste too much time on it…get a LAN cable and enjoy your vacation!

  • Agreed. Thanks for the feedback. I have a network cable with me… no place to plug it into.

  • Just ran a pacman update and noticed this with “wireless-regdb” anything to worry about?

    upgrading wireless-regdb  
    country 00: invalid
    
  • Not unless you are having problems connecting to any/all wifi access points.

    Cheers!
