I use the Internet through a Beeline VPN, I set it up quickly. The adapter has been constantly plugged into the network for 3 months and does not heat up. If you turn it off, then after turning it on, you need to wait 1 minute. until the connection with the server is established, the same if you change the settings and restart the adapter. I didn’t download the new firmware, I don’t see the point and it works stably. There are several firmware options on the manufacturer's website, maybe someone else will do. The equipment used is a telephone, a TV with WIFI, a Chinese whistle from aliexpress, a computer is connected via cable.
