The internet becomes unavailable late at night

[Aruupaka]

I don't know why, but lately my mobile boardband has been slowing down every night after 12pm, with a latency of 200 ping, and download speeds of 10mbps. the internet was fine until 11pm so I'm sure it's not congestion, and it usually happens instantly after a certain time, one game I'm playing fine but the next one I try turning off ipv6 and it improves a little but not much. one game I'm playing fine but the next I'm lagging. I tried turning off ipv6 and it improved a little but not much. I also tried connecting to just 4g which made the state of the network worse.

Thanks for confirming this @Aruupaka. It does sound like an issue with the local network if it's affecting multiple SIMs and devices. Possibly a network congestion issue. Have you reported the issue with our Broadband team?

Thanks,
Jonathan

I think I know why, as soon as I get to midnight my internet changes from 5G to 4G,I think it's because Three stops supplying me with a 5G signal in the middle of the night. This is unacceptable to me as I pay for 24/7 access to 5G and if this continues I will have to switch to a new carrier.
