You don't need an "SSID number." **SSID = Wi-Fi Network Name** (e.g., "HomeNetwork," "CoffeeShop_WiFi"). It's a name, not a number. Your PSP scans for it automatically.
| Problem | Fix |
|---|---|
| SSID not found | Router: Enable 2.4 GHz (PSP doesn't support 5 GHz). Disable "Hidden SSID." |
| "Security Mismatch" | Router: Set to **WPA2-PSK (AES)** only. Not "Mixed," not "TKIP." |
| DNS Error (8041040F) | Custom → DNS Settings → **Manual** → Primary: `8.8.8.8`, Secondary: `8.8.4.4` (Google DNS) |
| Proxy Error | Custom → Proxy Server → **Do Not Use** |
| Connection times out | Restart router. Move closer. Check MAC filtering on router. |
Bottom Line: SSID = Network Name. Scan → Select → Enter Password → Done. Use WPA2-AES + Google DNS for best reliability.
