Internet Speed Evaluation: Employ internet speed testing services like Fast.com or Speedtest.net to assess your download and upload speeds.

Network Troubleshooting: If sluggish internet speeds are hindering connectivity:

Router and Modem Reboot: A simple restart can often rectify temporary network glitches. Power cycle both your router and modem for optimal results.

Wired Ethernet Connection: For the most reliable connection, prioritize a wired ethernet cable over Wi-Fi whenever possible.

ISP Contact: Should issues persist, reach out to your Internet Service Provider (ISP) for further assistance.

Party Settings Verification

Occasionally, the issue might lie within your friend's party settings:
