League of Legends Known Issues, Workarounds and Fixes

Concurrent downloads or streaming can increase buffering

Riot lists video streams, torrent programs and active downloads among applications that can increase buffering. This is a troubleshooting category rather than proof that any installed application always causes lag. [1]

Attempting to Reconnect, lag spikes or packet loss

Riot’s connection guide separates server, internet-provider and local-equipment causes. A connection symptom alone does not identify which side is responsible. Checking regional server status comes before changing local network settings. [1]

Documented steps

1. Check the regional server status. Where available, use the region’s Lag Report to compare the recent Connection Score with other players and internet providers. [1]
2. Where practical, switch from wireless to Ethernet to remove wireless interference as a troubleshooting variable. [1]

Connection issues continue after the basic checks

Riot’s game-specific connection page recommends its Automated Repair Tool as a way to address connection trouble and collect support logs. It also directs persistent cases to advanced connection troubleshooting. When opening a support ticket, the requested material includes network analysis, trace route and a process list; supplying that material is an investigation step, not a guaranteed server repair. [1]

Documented steps

1. Use the Riot Repair Tool referenced by Riot’s support page for the next diagnostic check. If the issue persists, include the requested connection logs in a private Player Support ticket. [1]

LP falls during inactivity in Diamond or above

Inactivity decay is a documented Ranked system for Diamond and above. Banked days run down over time; once empty, the queue can lose LP without another played loss. [2]

Documented steps

1. Play matches in the affected Ranked queue to earn banked days before they are exhausted. [2]
