Antivirus and firewall software installed on the computer can sometimes hamper online gaming. They are meant to shield your machine from viruses, but they often create false positives by blocking legitimate programs like League of Legends.

Launch the game after disabling the anti-virus to see whether the download speed has changed. If the game runs well, add the game file to the list of exceptions in your antivirus program settings.
