PSP Wi-Fi via Windows Vista Laptop: Not Direct – Use Router or CFW

You cannot directly connect a PSP to a Vista laptop via Wi-Fi for internet sharing easily. Vista's "Internet Connection Sharing" (ICS) + Ad-Hoc is buggy, slow, and PSP only supports 802.11b (2.4GHz) + WEP / WPA-PSK (TKIP) – Vista defaults to WPA2-AES.

Real Solutions

1. Use a Router (Standard): Connect Laptop + PSP to same Router (Wi-Fi or Laptop Ethernet + PSP Wi-Fi). Simplest, stable.
2. PSP Custom Firmware (CFW/HEN) + USB:
   • Install 6.61 PRO-C2 / ME / LME or HEN.
   • Run USBHostFS_PSP or PSPLink on PC → Access PSP files / Run homebrew / Debug.
   • Not for internet sharing.
3. Phone Hotspot (Best Portable): Phone → Hotspot (Set 2.4GHz, WPA2-PSK) → PSP Connect. Works if PSP supports WPA2 (3000/Go/Street do; 1000/2000 may need WEP).
4. Travel Router (GL.iNet, TP-Link Nano): $20–30. Plug into Hotel/Ethernet → Creates Wi-Fi (WEP/WPA) → PSP Connects. Reliable.

Vista ICS (If You Must)

1. Control Panel → Network and Sharing Center → Manage Wireless Networks → Add → Create Ad-Hoc Network.
2. Security: WEP (PSP 1000/2000) or WPA-PSK (TKIP) (3000/Go). No WPA2-AES.
3. ICS: Adapter Properties (Internet) → Sharing → Allow others → Select Ad-Hoc Adapter.
4. PSP: Scan → Connect.

Vista is EOL (2017). Security risk. Upgrade to Win10/11 or Linux.
