It's been so many days, and nothing improved. I literally tried everything, but nothing works.
Yesterday I installed link sys router app and reset the router properly, tried to change the DNS,test speed shows good results. But everything is slow.
Whatsap call or video call
In the past week, few times at night I got good internet, but in the last few days, everything is too slow, it feels like 2G connection.
Can someone help?
