I am running an Wi-Fi connection of our university residential hall. When I browse Internet or Download something it is about 300 kBps speed.
But in the terminal the connection is too slow and gets slower & then gradually tends to 0 kBps i.e. "No Internet". In average I get about 4kBps speed for any case. apt update, wget, curl, composer --- all are so slow that cannot complete even "apt-get update" command.
Before, this problem did not occur but recently, I am very upset now.
I cannot install anything from terminal.
N. B. Firewall is disabled as default.
