Solving Steam Error Code 105: A Comprehensive Guide

Steam is a favorite platform for gamers worldwide, but like any technology, it’s not without its quirks. One of these is the notorious Steam Error Code 105, which can abruptly halt your gaming sessions with an "Unable to connect to the server" message. This error generally arises from network-related issues, and we’re here to offer a quick and definitive guide to help you tackle this problem head-on.

What is Steam Error Code 105?

Steam Error Code 105 usually indicates a failure to connect to the internet, preventing you from accessing the Steam store or community features. This often stems from DNS problems, network settings, or temporary service disruptions. Understanding these root causes is the first step toward resolving the issue.

Common Causes of Steam Error Code 105

Network Connection Issues

• Unstable Internet Connection: If your internet connection is unstable, Steam might have trouble connecting to its servers.
• Weak Wi-Fi Signal: A weak Wi-Fi signal can also be the culprit behind connection problems.

DNS Configuration Errors

• ISP’s Default DNS Servers: Sometimes, the default DNS settings provided by your internet service provider may fail to resolve Steam’s server IP addresses properly.

Firewall and Security Software

• Overprotective Firewalls: Security software can sometimes block Steam as a potential threat.
• Antivirus Software: Antivirus interference often leads to Steam connectivity issues.

Step-by-Step Guide to Fix Steam Error Code 105

Step 1: Check Your Internet Connection

1. Restart Your Router/Modem: Unplug your router or modem, wait for about 30 seconds, and plug it back in. This often resolves temporary connectivity issues.
2. Switch to a Wired Connection: If you’re using Wi-Fi, try connecting your computer directly to the router with an Ethernet cable to ensure a stable connection.

Step 2: Change DNS Settings

1. Use Google DNS: Switching to a free public DNS like Google’s can help solve DNS issues.

   • Open your network settings and manually set the DNS server addresses to 8.8.8.8 and 8.8.4.4.

2. Flush DNS Cache:

   • Open Command Prompt as an administrator.
   • Type “ipconfig /flushdns” and press Enter. This will clear any potentially corrupt DNS cache.

Step 3: Check Firewall and Antivirus Settings

1. Allow Steam Through Firewall:

   • Go to the Control Panel and navigate to the Firewall settings.
   • Ensure that Steam is allowed to connect through Windows Firewall.

2. Disable Antivirus Temporarily:

   • Temporarily disable your antivirus software and check if the issue persists. If this resolves the problem, consider adding Steam as an exception.

Advanced Troubleshooting Steps

Step 4: Reset Network Configuration

1. Network Reset:

   • If basic troubleshooting fails, opting for a network reset can be beneficial. This can reset all network-related settings on your computer.

2. Winsock Reset:

   • Open Command Prompt as an administrator.
   • Type in netsh winsock reset and press Enter. This resets the Windows Sockets API, which can correct network-related anomalies.

Step 5: Update Drivers and Steam Client

1. Update Network Drivers:

   • Ensure that your network drivers are up to date. Visit the website of your network card manufacturer for the latest driver updates.

2. Ensure Steam is Updated:

   • Check for any available updates for the Steam client and install them as outdated software versions can contribute to connectivity issues.

Preventive Measures

• Keep Software Updated: Regularly update your operating system, network drivers, and Steam client.
• Regularly Restart Hardware: To prevent future errors, make a habit of restarting your router or modem regularly.
• Secure Wi-Fi Passwords: Ensure that your Wi-Fi network is secure to prevent unauthorized access, which could affect the connection quality.
