Hello,
You had a problem in my building last Friday and, since then, my router does not function properly. Yes, I am aware this is probably not a network issue but a wifi one, but it has been working fine since we moved in July and, after this problem you had, it started working wrongly.
Even Chromecast, which sits next to the box is lagging and stopping constantly. This had never happened before.
Ping to 8.8.8.8 is very unstable and it is impossible to work like this.
