I had the same problem. Could not connect to either ethernet or wireless. Wireless would not detect any access points, and the WLAN light would not flash. I manually typed in my SSID and WPA password and it still would not connect (Error 8001000A). I turned my PS3 off and almost immediately turned it back on. The network settings had remembered the wireless settings I had previously entered. When I tested the connection, everything worked.
Then I stumbled upon this thread, haha. Wish I had found it sooner. Since my PS3 is under warranty, Sony is sending me one of those prepaid box things. Do you think it would be worth it for me to send in my PS3 anyways? This is such a headache.
I'm downloading Wipeout HD Fury while it still works.
My PS3 was updated to the latest firmware when I had this problem. Been playing Battlefield 1943 all weekend over wifi and havent had a problem. I haven't tried to scan for other networks out of fear of losing my connection again. I suppose I will investigate more once the mailing box arrives from sony.
As an update: When I ugraded to version 3.0 last night, all my wireless problems were resolved. My PS3 can now scan and detect wireless networks in my vicinity. This was great news for me, because I almost mailed my system to sony.
Way to go Sony.
I was going nutz trying to get mine to work, reading hundreds of posts to no avail.
Last night however I tried something new.
I setup my Network connection via the "Custom" menu.
Took all my laptop wifi settings and mirrored them.
Primary and Secondary DNS
There was one last field that didn't quite have a 1 to 1 correlation I used the Default Router values.
Bingo Bongo, I was connected and updating!
Used my new Netflix DVD which just arrived and enjoye movie streaming for hours!
There is hope...
