Step-by-Step Repair

  1. 1

    Restart the console and router

    Power off the console completely. Unplug your router for 30 seconds. Plug the router back in, wait 2-3 minutes, then turn on the console. This clears network caches on both devices.

  2. 2

    Test your internet speed

    Run a network speed test from the console's settings. Compare with a test on your phone. If the phone gets good speeds but the console doesn't, the issue is between the router and console specifically.

  3. 3

    Use 5GHz instead of 2.4GHz

    If your router broadcasts both bands, connect the console to the 5GHz network. It's faster and less prone to interference. Position the console closer to the router if 5GHz signal is weak.

  4. 4

    Change DNS settings

    Set DNS to Google (8.8.8.8 / 8.8.4.4) or Cloudflare (1.1.1.1 / 1.0.0.1). Go to Network Settings > Advanced/Manual and enter the DNS servers. This can improve connection reliability and speed.

  5. 5

    Use a wired connection

    If WiFi problems persist, connect via Ethernet cable for the most stable connection. If the console is too far from the router, a powerline adapter ($30-$50) can send internet through your electrical wiring.

If That Didn't Work

  • ISP throttling gaming traffic
  • Too many devices on the same WiFi network
  • Console's internal WiFi antenna damaged

When to Call a Professional

If the console can't see any WiFi networks, the internal WiFi module may be damaged. This typically costs $40-$80 to repair. A USB WiFi adapter ($15-$25) may be a cheaper workaround.
