What’s the best way to connect an Xbox 360 to Wi‑Fi from another room without running Ethernet through the house?

A wireless bridge or access point with client/bridge mode is probably the cleanest solution. It connects to your existing Wi‑Fi and gives you Ethernet ports near the console, so you only need a short cable from the bridge to the Xbox. A spare router may work too if it supports wireless bridge or repeater mode. Check whether your current router can broadcast a separate 2.4 GHz network, since older Xbox 360 wireless hardware can be picky about newer Wi‑Fi settings.

Powerline adapters are another option. One unit plugs into an outlet near the router and the other goes near the Xbox, using your home’s electrical wiring to carry the network connection. They can work very well, but performance depends on how the outlets and circuits are wired, so buying from somewhere with a good return policy is sensible.

If you want the most reliable connection and can make small holes in the exterior walls, outdoor-rated Ethernet cable run around the outside of the house is worth considering. Use weather-resistant cable, protect the entry points, and keep the total cable length under the normal Ethernet limit. It will usually be more stable than wireless, powerline, or mesh.

A Wi‑Fi extender with an Ethernet port can do the same thing. Place it somewhere between the main router and the Xbox where it still receives a strong signal—not right beside the console if that location has poor coverage—then connect the Xbox to the extender with a short Ethernet cable. This also gives you extra ports for other devices.

A mesh system can work if you already have one, with the Xbox connected by Ethernet to a secondary mesh node. Just remember that the extra node needs to be placed where it still has a strong connection to the main node; putting it at the dead spot usually makes things worse. For a single console, a wireless bridge or Ethernet-equipped extender is generally cheaper.
