Archer MR600 QMI crashes?
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Recently I bought a TP-Link Archer MR600 because I moved to a new apt and the internet infrastructure in the area is bad (but that's a different story that I won't go into).
on good days the 4G router behaves as it should and gives me a stable connection via my mobile service provider.
On the other hand, the router has a tendency to crash with a QMI error, this is the error code: ERROR: 0x0000000E QMI_ERR_CALL_FAILED
Here's a system log I grabbed from the admin interface of my Archer MR600:

I live in Israel (HOT Mobile is my mobile service provider), and to answer a few questions that some of TP-Link's forum moderators may have:
1. The SIM is stable if I use it in my phone/tablet.
2. when the MR600 crashes, the 4G LED turns off.
3. I have an IP address when the router crashes.
The router sometimes manages to recover and the connection gets restored, but sometimes I'm forced to reboot the router.
I'd like to know how to prevent these crashes in the future
Hey, thanks for the response, I'll try to answer as best I can because I work quickly when my internet crashes.
> Have you tried to manually fix the 4G bands on the MR600 v2?
Most of the time, my internet connection crashed when the MR600 V2 band selector was set to auto.
> When the internet crashed, if you manually change the network type under Advanced>network>internet to be 3G only, would the internet recover?
To be honest, I didn't try this.
> Could you please leave me some pictures of the Advanced>status page before and after MR600 crashed?
Almost no change before and after crash
