Great router! I recommend!
We are waiting for the firmware (and it will definitely be, because the device is mega-promising), in which the GLOBAL flaw will be corrected. In the meantime, this is "treated" by setting the modem to the "3G only" mode (or "2G only", "4G" mode).
In addition to this router, I also bought a TL-MR3040, the hardware is the same, respectively, and the firmware, but with a removable battery. The downside, unfortunately, is the same.
