Hello. I am here again.
I have intenet connection issue. It starts while ago, almost since I became T-Mobile Home internet customer. Internet connection was lost regulary, I even find out some fixed times then it happen. It was at 12PM and 2:22AM. But last days it became absolutely terrible. Sometimes connection can be lost maybe 20 times per 30min.
I mean, green web light in modem gone, later become red, internet is back and then cycle start again. Maybe it can be important information, then connection lost I got ERR NETWORK CHANGED message in browser.
Lets skip modem reset and cables step. Checked and reseted many times.
