Thanks for your replies.
I contacted my landlord because none of the passwords on the bottom of the hub seem to be working but for some reason he’s not providing me with the login details.
The first time this happened was exactly 09:06 am on Friday the 18th of Feb, the next one 10:45 last Saturday, the 26th. The first time the hub went all off, I haven’t touched it, and it connected again 30-40 minutes later (update or something). The second time, I received 1.5-2.0k ping for a few seconds, the TeamSpeak3 froze for a bit and disconnected, and after less than a minute it was back to normal.
I’m completely green but I was just wondering if anybody would be able to tell me what the issue MIGHT BE before I start a tyrade with the landlord or get my own broadband. And also if this might be some kind of restart that hubs do at certain time (and if I’d be able to change it to less disturbing one), or maybe the second time was just a random ping spike?
