Internet is very slow on LineageOS (latest build) on xiaomi mi 3w

[Wilhelmalex726]

Hello guys, today I just clean flashed the latest lineageOS build for my xiaomi mi 3, But when I was in MIUI 9, My internet speed was normal, but after I flashed the latest LineageOS, My internet speed suddenly became slow but I can connect to the internet. It's just too slow for my device when i flashed the rom. Is the rom the problem or is it our internet/router?
