Hello, O2 Team,

I have been using my HomeSpot since August 2023 and everything seemed OK. Normally i had speed around 5-20 Mbps, sometimes even more. But suddenly, on Monday (21.04) the internet speed dropped under 1mbps (around 0.25-0.8 Mbps, rarely around 1-1.5mbps). I’ve tried everything, but nothing helps. I went to the O2 store where I signed my HomeSpot contract, and the worker said that there are some problems with the network on my street, and I should wait until next Monday. So, today is this Monday (29.04) and nothing really changed. For a few minutes speed became good this evening but then it dropped again. I also have a friend who lives on the same floor with me, and he also uses o2 but has no problems. Here is a list if things I tried to do, in order to fix my internet:
1) Changed preferred network in router settings (Did it a few times, on different days)
2) Tried changing router position, the connection is very good, but speed is still very poor
3) Restarted router
4) I even tried to put the sim-card directly into my phone and tested speed there, but it also didn’t change anything
5) Went to https://www.o2online.de/netz/netzstoerung and typed my address there, it also says that everything is ok.

So I tried my best to find the problem, but I simply can’t do anything. It looks like there is some problem with a Sim-Card, because speed remains low, no matter in which device i put the Sim. At this point, I simply don’t know what to do.

Sometimes the speed even drops to complete zero

The upload speed is also strange, sometimes its also under 1mbps and sometimes its around 10-15 mbps (like on that screenshot)
