    The shutdown text, logs, and pppd man pages point to the same program: error 16 means the switch is shutting down. I verified that ppp and async listed in the config menu might have been enabled, tried “Stupid mode is on” in wvdial. conf and changed my personal init strings hoping it would work.

  • I’m trying to use any 3G USB modem on the Rapsbian RPi and it’s fine unless PPP is disabled with exit code 16 for some reason.I’ve turned on debug mode, but I don’t like anything except that the authentication was successful.

    Why Do I Finally Need To Complete The CAPTCHA?

    What Can I Do To Avoid This In The Future?

    If you have an active personal connection, such as at home, your device may run a virus scan to make sure it is not infected with malware.

    If you’re in an office or on a distributed network, you can ask the chief administrator to scan the network for misconfigured and infected devices.

    Another way to prevent this how-to page from appearing in the future is to use the Privacy Pass. You can download the Firefox Store add-on version 2.0 right now.

    I’m currently experimenting with connecting a UK Giffgaff 3rd Gen network to a ThinkPad X240 built-in USB modem.

    wvdial error 16

    The expert service provider explicitly states that the APN is giffgaff. The com username was still giffgaff, the password on the card had to be left blank. As I read, wvdial treats our “empty” string as a password, but I also tried with Password=*unfilled. I’ve tried with the APNs “giffgaff”, “internet” and also my own giffgaff password, without much success.

    I don’t know where to look for the source of this error: the modem and service provider are new to me for a lot of people. When reading the forums, you may encounter another error due to incorrect identification or APN username or problems with the data compression control protocol.

    I would really appreciate it if you could point me where to look next. Is this problem related to the switch, connection settings, or individual pppd settings? Also, how do I enable more informative debug messages?
