league of legends connection issues – high ping, packet loss, disconnecting mid-game, or failing to connect at all – are usually fixable and almost always network-related. here’s the systematic fix process.
Step 1: Check Riot’s server status
Before doing anything on your end, confirm the issue isn’t server-side: status.riotgames.com shows real-time status for LoL servers by region. If there’s a known outage, wait it out.
Step 2: Run the Windows network troubleshooter
Settings > Troubleshoot > Other troubleshooters > Internet & Network > Run. This catches common network configuration issues automatically and may fix them without further steps.
Step 3: Flush DNS and reset Winsock
Open Command Prompt as administrator and run:
ipconfig /flushdns
netsh winsock reset
Restart your computer after running these commands. DNS cache corruption and Winsock catalog issues are common causes of game connection problems that look like ping spikes or failed connections.
Step 4: Check for background bandwidth usage
Other applications consuming bandwidth during a game cause packet loss and high ping. In Task Manager > Performance tab > Open Resource Monitor > Network tab, check which processes are sending/receiving data. Close anything doing significant network activity – cloud backup, Windows Update, streaming, browser tabs.
Step 5: Switch to wired Ethernet
WiFi causes variable latency. Wired Ethernet gives consistent, low ping. If you’re on WiFi and experiencing connection problems, a temporary wired connection confirms whether WiFi is the cause.
Step 6: Firewall and antivirus exceptions
Overzealous firewall rules can interfere with LoL’s connection. In Windows Firewall settings, make sure League of Legends and the Riot Client have allowed inbound and outbound rules. Some antivirus real-time protection can also cause packet loss – try temporarily disabling it to test.
Step 7: Change DNS servers
Slow or unresponsive DNS servers can cause connection delays. Change to 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google) as described in the DNS fix earlier.
Step 8: Contact your ISP
If the above steps don’t resolve persistent issues, run a traceroute to Riot’s servers: tracert 104.160.131.3 (NA server IP). If you see high latency or packet loss at a specific hop, the issue is between you and that routing point – something your ISP may need to address.
