Fix Monster Hunter World PC Disconnects Fast

Monster Hunter World on PC is prone to disconnects, especially during multiplayer hunts. This guide walks you through the most effective fixes, from Steam network settings to Windows firewall rules, so you can stay connected through the end of the quest.

What You’ll Need

Windows PC with Monster Hunter World installed
Administrator access to your Windows account
Your router’s login information (usually found on the router label)
Steam client installed and logged in

Step-by-Step

Verify your game files. Open Steam, right-click Monster Hunter World in your Library, select Properties > Installed Files > Verify Integrity of Game Files. Wait for the process to complete. Corrupted files often cause random disconnects.
Set Steam to a low ping server. In Steam, click Steam > Settings > In-Game, then set “In-Home Streaming” to off. Next, go to Steam > Settings > Downloads and click “Download Region.” Choose the server closest to your physical location. This affects matchmaking and connection stability.
Disable Steam Overlay for the game. Right-click Monster Hunter World in Steam, select Properties, and uncheck “Enable the Steam Overlay while in-game.” The overlay can interfere with Capcom’s network layer.
Allow the game through Windows Firewall. Open Windows Security > Firewall & network protection > Allow an app through firewall. Click “Change settings,” then “Allow another app.” Browse to the game’s executable (usually Steam\steamapps\common\Monster Hunter World\MonsterHunterWorld.exe) and add it. Ensure both Private and Public checkboxes are ticked.
Set the game to high priority in Task Manager. Launch the game, then press Ctrl+Shift+Esc. Under the Details tab, right-click MonsterHunterWorld.exe, select “Set priority” and choose “High.” This prevents background processes from stealing network bandwidth.
Disable Windows Game Mode and Game Bar. Go to Settings > Gaming > Game Mode and turn it off. Then under Captures, disable Game Bar. These features can throttle network traffic for non-UWP games.
Change your DNS to Google’s public DNS. Open Control Panel > Network and Internet > Network and Sharing Center > Change adapter settings. Right-click your active connection, select Properties, then Internet Protocol Version 4 (TCP/IPv4). Use these DNS servers: 8.8.8.8 and 8.8.4.4. Click OK and restart your PC.
Forward the required ports on your router. Monster Hunter World uses UDP ports 27000-27100 for Steam matchmaking. Log into your router’s admin page (usually 192.168.0.1 or 192.168.1.1), find Port Forwarding, and add a rule for UDP 27000-27100 to your PC’s local IP address. If you are unsure how to set a static IP, just set the port forwarding to your current IP and enable DHCP reservation if available.
Limit Steam download bandwidth. In Steam Settings > Downloads, set “Limit bandwidth to” to 1 Mbps or lower. Even when not downloading, Steam can use bandwidth for updates and background tasks, which can cause packet loss in MHW.
Disable any VPN or proxy software. If you use a VPN, turn it off completely before launching the game. Capcom’s servers are sensitive to IP masking.
Run the game as administrator. Right-click the game’s .exe file, select Properties > Compatibility, and check “Run this program as an administrator.” This ensures the game can open all necessary network sockets.
Update your network drivers. Go to your motherboard or laptop manufacturer’s website, download the latest LAN/Wi-Fi driver, and install it. Outdated drivers are a common cause of intermittent disconnects.

Common Mistakes

Only forwarding TCP ports. Monster Hunter World primarily uses UDP for multiplayer. Forwarding only TCP will not help.
Using a Wi-Fi connection. Wireless connections suffer from interference and jitter. A wired Ethernet connection dramatically reduces disconnects.
Forgetting to restart after DNS changes. DNS changes only take effect after a full system restart or an ipconfig /flushdns command in Command Prompt.
Blocking the game in antivirus. Some antivirus suites (like Avast or Bitdefender) have “Game Mode” or network shields that block multiplayer traffic. Check your antivirus’s blocked apps list.
Playing during Steam sales or peak hours. High load on Valve’s matchmaking servers can cause disconnects that are not your fault.

Tips

Use a wired connection. If possible, connect your PC directly to the router with an Ethernet cable. This is the single most effective fix.
Play during off-peak hours. Try playing in the morning or late night if you keep disconnecting during evenings.
Check your router’s QoS settings. Enable Quality of Service and prioritize your PC’s MAC address for both upload and download.
Disable IPv6 on your network adapter. Some ISPs have broken IPv6 routing. In adapter properties, uncheck “Internet Protocol Version 6 (TCP/IPv6)” and restart.
Use a session join instead of SOS. Joining a session via the Gathering Hub is often more stable than responding to SOS flares, which rely on peer-to-peer connections.

Troubleshooting

If you still disconnect after trying all steps, work through these in order:

Test with another online game. If other games also disconnect, the issue is your network or ISP, not Monster Hunter World. Contact your ISP.
Check the MHW server status. Capcom’s servers occasionally go down for maintenance. Visit the official Monster Hunter status page or the game’s Steam community hub to see if others are reporting issues.
Try a different router. If you have a spare router, swap it in. Some routers have faulty NAT tables that drop connections under load.
Disable Windows Defender Firewall entirely (temporarily). If the game connects with the firewall off, your firewall rules are wrong. Re-enable it and re-add the game as an exception.
Check for background downloads. Windows Update, Steam, or Epic Games Launcher might be downloading in the background. Open Task Manager and look for high network usage.
Reinstall the game. As a last resort, uninstall and reinstall Monster Hunter World. This fixes any deeply corrupted files that the verify step missed.

Frequently Asked Questions

Why do I only disconnect during multiplayer hunts, not solo?

Solo play uses no network connection. Multiplayer uses peer-to-peer connections between players, which are less stable than dedicated servers. Your connection to the host player matters.

Is this a known issue with the Steam version?

Yes, the Steam version has had connectivity issues since launch, particularly with NAT traversal. Capcom has released patches, but many fixes are on the player’s side.

Does using a VPN help or hurt?

It usually hurts. VPNs add latency and can break NAT traversal. Only use a VPN if your ISP is blocking the game’s ports, and even then, a port forward is better.

Can I play with friends in another country?

Yes, but long-distance connections are more likely to disconnect. If you and your friends are far apart, try having the player with the best internet host the session.

Will setting the game to high priority damage my PC?

No, it just tells Windows to give the game more CPU time. It reverts to normal when you close the game.

Do I need to forward ports if I use a VPN?

No, VPNs bypass port forwarding entirely. But as mentioned, VPNs are not recommended for this game.
