Quickly and easily set up. The router consistently gave out 20-25 Mbit / s for input and 15-20 Mbit / s for output. After a month and a half of work began to blunt. Lose connection to the cellular network. The input / output speed dropped to 1-2 Mbit / s, or even to 0. I thought the problem was with the base station or Simcard. Inserted into another router, everything is OK. Restarted, reinstalled. Problem still exists. You can see something with iron.
