Hello everyone,

Currently in Germany me and some people are having internet connection stability issues with 5G connection. The band I connect is Non-standalone so I don't really get 5G speeds, or low latency, even when the app shows it is connected via 5G. And I have found out this 5G connection was very unstable when opening speedtest, or simply opening Instagram from my phone, or using Parsec to connect to my other pc. All the devices would lost connectivity, and app would say "you have internet connection" and led would be also white which indicates there is no issue. However I tried pinging 1.1.1.1 from my PC and of course packet loss was %100. I blamed the heat problem however it is not overheated when I touch, even feels like less warm than normal modems. Tried ECO mode, tried different DNS, tried different firmware (1.3.0), locking bands (B20, N78) because best signal and +300mbps speed, factory resetted, tried QoS... And many things I cannot remember. I have been dealing with this issue since 3-4 months. And thanks to other forum users answers I was able to find solution.

Solution;

Simply change to 4G only from Deco app. And it will use 4G+ connection if you don't lock the bands (select auto for bands).

and disable ipv6.

Result: 4G+ has literally same speed as 5G(non standalone) provides, and for ping it became more stable and jitter values dropped. Never lost internet connection even when using speedtest to measure, and on instagram, on Parsec. Everything worked fine. The issue is 5G.

Regards.
