Weird problem creeped into my PSP recently. The PSP won't connect to any wireless source, whether it's my PS3 or my wireless router. I was running 3.40-OE for the longest time and then all of a sudden (not sure when) it would no longer connect to the router. I couldn't figure out why this was happening so I upgraded to 3.52-M33, but that didn't fix it. I downgraded to 1.50, tried connecting, still got the same error. I'm back at 3.52-M33 and reset the flash1, still nothing. Reset the default settings in the PSP system menu, nothing.
There's only a MAC filter on the router, no WPA/WEP encryption. I tried turning off the MAC filter, and it still doesn't connect. My desktop and PS3 connect wirelessly to the router just fine.
The connection error simply says "Error connecting, check security settings on router". I know the wireless portion of the PSP still works because I can scan for other networks and it will pick up the radio of other networks, but it can't connect to any of those either...
Anyone have a clue?
