    I have an issue that only occurs on a device pair: an ArchLinux [with the latest kernel] Asus UX31A machine and a VirginMobile 4g hotspot.

    It appears that the internet connection on my laptop stops working, but remains connected to the hotspot after ~4 minutes/3MBs of data.

    From my tests I have found that:

    1. This occurs anywhere.
    2. This occurs even if the device is operating on the battery or not.
    3. I'm able to regain access after I disconnect from the hotspot and I reconnect to it.
    4. When I lose internet access I am not able to get access to 192.168.0.1 [the device's management page]
    5. My account with Virgin Mobile is in full paid standing.
    6. This occurs on 4g and 3g access.

    How would I got about debugging this further? This is the only pair of devices that has this issue?

    mac - Macbook WiFi won't connect to public wifi hotspots, but works fine otherwise
  • Matt H.

    I've looked at other posts with similar keywords, but none of them seemed to apply quite right.

    (I have a Macbook purchased in June 2008)

    I am able to use my home wifi, the wifi at my mom's house, and even my neighbor's unsecured connection.

    However, every public wifi spot I've tried to work at fails. I AM ABLE TO "connect" to the network (Airport shows I am connected), but when I open a web browser I get a "Not connected to the internet" message. This has now occurred at four different locations. (Also, at one of them, I tried to connect with my iPod touch, and i was able to get online without issue.)

    Also, when I first bought this macbook, I did not have this issue.

    Any helpful suggestions? Thanks!

    Do you have a static IP address assigned to your Airport interface for some reason? How about statically assigned DNS numbers? If that is the case, it might be a coincidence that the assigned address information is compatible with the neighbors's and mom's networks.

    Try making a new network location. Go to System Preferences >> Network pane. At the top there is a pull down menu for Locations. Pull it down and select Edit Locations. Make a new location named Test. Click on the Apply button in the lower right.

    This will give you a completely new network configuration with all interfaces set for DHCP. You may always change the location back to whatever the old one was if you need to.

    I had the same problem.

    The key for me was that I had a custom DNS server configured. In my case it was googles (8.8.8.8). I remember doing this some time ago for whatever reason.

    Anyway, the public hotspots don't seem to like this. After removing the custom DNS server I was able to connect fine on public hotspots.
