A couple of questions:
When you say you have ports forwarded etc, are you accessing the PL4 from a remote network/location? Over the internet?
What is your PL4 firmware and WiFi module firmware version?
No trying to access it via the same network. Firmware and Wifi both using the latest versions.
I had success logging into the web interface on the P4 and enable wifi there also, then wait around 20 minutes after reboot before trying wifi again (of course adding the P4 manually and not auto detection).
