To follow up on this, it may also depends on your type of walls you may have sometimes. Maybe if you can send pings out to like Google DNS or other servers to see if you get any high latency (ms time) if its high, there could potentially be some kind of issue with the line.
Maybe there is something, correct me if I am wrong anyone.
