"Raise your hand or paw if you're with me!" – The Admiral, Monster Hunter: World

Please follow these troubleshooting steps to help resolve any network / connection-related issues.

1. Check the status of the Steam servers
First, check to see whether the Steam servers are experiencing any network outages. If there is an outage, check the official Steam Support Twitter page to stay up-to-date on when it is OK to connect again.

2. Ensure other online devices are turned off prior to playing
Internet speeds of 15-20Mbps (Megabits per second) are oftentimes sufficient enough for online gaming. However, homes could have several devices connected to the internet at one time. If the home uses the internet for other things like streaming music, watching movies, and working from home, this can all put a strain on your bandwidth. We recommend ensuring other devices using the internet at home are turned off while playing online.

3. Reboot your PC and refresh your modem and router
Try exiting the game and rebooting your PC, as well as refreshing your modem and router connection by unplugging both devices for a few minutes, then re-plugging the modem, followed by the router. If other devices, such as another PC/Mac or smartphone are also connected and being used on the network, please disconnect or refrain from using them while playing online.

If using a router or CTU with a UPnP function, please confirm whether this function is ON. If it is OFF, please turn it ON and try connecting online again. Please also ensure that packet filtering is turned off on both your router and with your Internet Service Provider.

If there are 2 routers being used, we recommend putting one of these routers in Bridge Mode. For more information on this mode, we recommend consulting your router’s manual.

*If you are unsure of the appropriate setting regarding port opening and UPnP function, please contact your router manufacturer/provider.*

Finally, additional PPPoE settings may be required for your modem and/or router. For further details, please check with your Internet Service Provider.

4. If using WiFi, switch to a wired Ethernet connection
A wired Ethernet connection is recommended when playing Monster Hunter: World online. If you are already connected via Ethernet, try connecting the Ethernet cord from your PC directly to the modem, thereby bypassing your router.

5. Check your Windows Firewall and Anti-virus settings
Your online experience for Monster Hunter: World may improve by ensuring your Windows Firewall is properly configured. Please ensure the MonsterHunterWorld.exe is added to your Windows Firewall and Anti-virus exceptions. MonsterHunterWorld.exe is located here:

C:\Program Files (x86)\Steam\steamapps\common\Monster Hunter World

6. Check your NAT (Network Address Translation) settings
Issues with connecting to a match online could be related to the NAT settings of your network. Network connections at universities / college dormitories, for example, generally impose some form of strict NAT (Network Address Translation) type which can cause issues with connecting to some online games. If you have strict NAT settings, you may have difficulty connecting to online game servers. We recommend double-checking the NAT settings for your PC to determine which type is set.

PC NAT settings can be found by accessing your modem / router’s menu. For more information on accessing this menu, please contact your modem / router manufacturer.

NAT Type 1 (Open) – You are either not behind a router/firewall or you have DMZ enabled. This NAT type shouldn’t run into any issues while gaming, however this may cause security issues.
NAT Type 2 (Moderate) –Your console is connected properly and you shouldn’t run into any issues.
NAT Type 3 (Strict) – You may be able to connect online and perform downloads/updates but other functions may not work as intended.

7. Forward the necessary ports on your router
If you haven’t yet already, we recommend Steam users forward the following ports on their router. For a handy guide to port-forwarding, please click this link. Please also contact your Internet Service Provider to ensure they are not blocking any of the following ports.
