The PSP-E1000 (Street) has no physical Wi-Fi switch. Wi-Fi is toggled in software:
Note: E1000 only supports 802.11b (11 Mbps max). Modern routers must enable "Legacy 802.11b/g" or "Mixed" mode. Disable Wi-Fi 6 (802.11ax) if issues persist.
Update firmware via Settings → System Update → Update via Internet (requires connection) or PC/Media Go.
