Checking Network Connectivity
Network connectivity is the first thing to check for System Error 1231. Start by making sure your computer is connected to the network. Check if the Ethernet cable is plugged in securely or if the Wi-Fi signal is strong. Try to ping the router using the command prompt. This tests if your device can reach the network. If the ping fails, the problem is with the network connection.
Next, confirm that IP settings are correct. Use ipconfig to see your IP address. It should be in the same range as your network. Wrong IP settings cause communication issues.
| Check | What to Do |
|---|---|
| Network Cable | Ensure it is properly connected |
| Wi-Fi Signal | Check signal strength and reconnect |
| Ping Router | Use command prompt to test connection |
| IP Configuration | Verify IP address matches network range |
Resetting Tcp/ip Stack
Resetting the TCP/IP stack can fix the System Error 1231. This error happens when the network settings are broken or wrong. To reset, open the Command Prompt as an administrator. Type netsh int ip reset and press Enter. This command clears old settings and sets the TCP/IP stack back to default.
After running the command, restart your computer. This step helps apply the new settings. If the error stays, check your network cables and router. Sometimes, a simple restart of the router helps too. Resetting TCP/IP fixes many network problems fast and easy.
Adjusting Firewall And Security Settings
Firewall settings can block network access and cause System Error 1231. Check if your firewall is too strict. Allow the program or service through the firewall. Sometimes, disabling the firewall temporarily helps find the problem.
Security software may also block connections. Lower security levels for trusted networks. Make sure the network is set as Private and not Public. This allows easier sharing and connection.
Use these steps to adjust settings safely:
| Step | Action |
|---|---|
| 1 | Open firewall settings from Control Panel |
| 2 | Allow app or feature through firewall |
| 3 | Set network to Private in Network Settings |
| 4 | Temporarily disable antivirus or firewall for testing |
