Xbox 360 Wired & Wireless Simultaneously: Not Supported

The Xbox 360 cannot maintain both a wired Ethernet and a Wi-Fi connection at the same time. Its network stack binds to a single active interface—whichever was connected last or manually selected.

Switching Between Them (Easy)

1. To go Wireless: Unplug Ethernet cable → Settings → System → Network Settings → Wireless Network → Select SSID → Enter password.
2. To go Wired: Plug Ethernet cable in → Console auto-detects, switches to wired (priority). No menu needed.

Why No Dual Connection?

• Routing Table: Single default gateway. Two interfaces = ambiguous routing for Xbox Live packets.
• Hardware: One MAC address per interface; Xbox Live auth ties to one console certificate.
• Protocol: Teredo/IPsec for NAT traversal expects one path.

If You Need Redundancy

• Use a router with dual-WAN/failover (e.g., Ubiquiti, ASUS Merlin) — console sees one Ethernet link; router handles ISP switching.
• Or a gaming router with LTE backup (some Netgear Nighthawk models).

One connection at a time. Plug or pair—don't expect both.
