Since last week or so my internet suddenly started to disconnect very often. The problem occurs on all devices in the house and if I'm watching a movie it stops playing, if I play a game I get disconnected, etc. It is extremely annoying and frustrating. It reconnects back in a couple of minutes, but can continue disconnecting/reconnecting every 10-15 minutes for some time. Then it goes back to normal for a couple of hours, but happens again and again. It was perfectly fine in the past 6 months since I moved in.
I have ExperiaBox 10A. The light becomes red when the internet disconnects, then it starts blinking with blue color, then back to red. It continues switching between stable red and blinking blue until it becomes green in a couple of minutes and the internet is back.
I already tried rebooting, factory resetting the modem, but it didn't help.
