Bought new internet, it’s fast but some games lose connection after a few seconds

Troubleshooting Connectivity Issues with Specific Online Games After Upgrading Internet Service

Upgrading to a faster internet connection can significantly enhance your online experience, especially for activities like streaming, browsing, and multiplayer gaming. However, some users encounter perplexing issues where certain games experience frequent disconnections shortly after starting, despite the overall increase in speed. If you find yourself in this situation, you are not alone—often, the root cause relates to network configurations such as Network Address Translation (NAT) settings.

Understanding the Issue

In recent circumstances, a gamer upgraded to a high-speed internet connection, which improved overall performance for most applications. However, they noticed that specific multiplayer games—such as Garry’s Mod and No More Room in Hell—would disconnect moments after gameplay began. Conversely, other titles like Chivalry 2 and League of Legends continued to operate smoothly.

The primary suspicion points toward NAT-related issues, which can influence how your router manages incoming and outgoing connections. NAT types—Open, Moderate, and Strict—affect how easily devices can communicate through the network firewall. Restrictive NAT types often cause connection problems, especially with peer-to-peer or dedicated server-based multiplayer games.

Diagnosing the Problem

The initial step is to determine whether NAT configuration is indeed the culprit:

Check Your NAT Type: Most gaming consoles and some PC network tools can display NAT status in their network or connection settings.
Identify Pattern of Disconnections: Notice if disconnects happen only in certain games or across all applications that require inbound connections.

Potential Solutions Without Upgrading Internet or Using Paid Software

While changing your internet plan might seem like a straightforward fix—such as opting for a more open NAT type—there are several configuration-based solutions you can try first:

Configure Port Forwarding:
Identify the specific ports used by the problematic games.
Access your router’s administration panel.
Set up port forwarding rules to open these ports to your gaming device’s IP address.
Enable UPnP (Universal Plug and Play):
Many modern routers support UPnP, which allows devices to automatically open ports as needed.
Ensure UPnP is enabled in your router settings.
Assign a Static IP Address to Your Gaming Device:
This ensures that port forwarding and NAT rules consistently apply to the same device.
Check Router Firmware and Settings:
