Xbox Live Connection Issues with Adapter: Need Details

To troubleshoot, I need:

• Adapter type: Official Xbox 360 Wireless Adapter? USB Wi-Fi? Powerline? Ethernet-to-USB?
• Error code / message: e.g., "MTU error", "DNS failure", "Can't obtain IP".
• Steps tried: Reboot router? Wired test? Other devices work?

Quick Checks

1. Test wired Ethernet directly to router — isolates adapter.
2. Update adapter firmware (if applicable).
3. Set DNS manually: 8.8.8.8 / 8.8.4.4 or 1.1.1.1.
4. Port forward / UPnP: 88, 3074, 53, 80, 443 (UDP/TCP).

Reply with details and I'll narrow it down.
