I recently installed Mathematica 10.3 on Arch Linux. I activated my license, and all seemed to be well, but when I reboot my computer, the MathID changes, and it shows that the software is not activated, so I activate again. I repeated this process about 5 times now, requesting a system transfer for my activation key, but it just keeps changing. What's weird is that it doesn't happen after every reboot. Sometimes I reboot, and it's still the same. Other times, it goes back to a previously activated MathID and I can use the software, after it had changed to another one on a previous boot. Anyone has any idea how to deal with this issue? Much appreciated.

  • $\begingroup$ @user21 No, it doesn't. Nothing changes. All hardware is the same. $\endgroup$ – mawoltest Jan 5 '16 at 3:27

    $\begingroup$ Did you solve the issue? I have the same problem under Manjaro (Arch Linux derivate) and Mathematica 11 and thought it was due to the new Network Manager 1.4 automatically randomizing the WiFi MAC Address. But you had the problem before MAC Address Randomization was introduced... $\endgroup$ – tonydo Mar 2 '17 at 17:11

It’s perhaps the WiFi-connection. On a Toshiba KIRA-107 (8 GiB RAM) with Debian-Knoppix the MathID stays stable, even between boots, when the WiFi-card is on and connected to the same wireless network. Don’t know if this helps.
