Ehhh thats really strange, you changed ti PPoE, PPoE is basically used to conenct to the ISP Radius server from the router. OK are you on ADL or cable network. Hopefully you should have got those username and password details from your ISP

I don't pretend to understand and wish I understood better. But perhaps more clarity would help.
My Linksys router is connected by ethernet to my Verizon modem. I guess to operate as a router, the Linksys sets up a default network, called 'linksys'.
(Verizon, meanwhile, sets up a default network connection called 'verizon'.)
If I open a browser and address the router, ie. 192.168.1.1 in the address bar, I get a 'Setup' page for the router. On the setup page I can change the basic settings for the router.
Since the modem is DSL, it requires, as you say, a PPoE connection along with a user name and password. I was using the Automatic Configuartion DHCP choice. So apparently this allowed me to connect other computers via ethernet to the router then choose the PPoE connection on those computers and providing the user name and password from there. The router, then just passed that information through the modem to the Verizon ISP
The computers with a wireless card, meanwhile, could 'see' the wireless network broadcast from the router and could connect to the router that way. But without the router having a PPoE connection through the modem to the ISP, computers connected to it wirelessly could not really connect to the ISP and get DNS addresses etc. I lease that is my current level of understanding.
The Support Tech who finally got some idea about what the problem was, did so when he took me to the 'Status' tab on the router setup page and the IP, Subnet Mask, and Default Gateway addresses all showed zeroes. His solution was not right though. He directed me to contact Verizon and have them setup the modem as 'bridge' instead of 'half-bridge' This lead to a barely civil conversation between me and a Verizon Tech who insisted that the modem worked so his job was done. Back to Linksys where a fifth Tech, finally got it right.
For 24 hours I'd been asking people what it meant when the little graphic on Networks and Sharing showed a green connection to the router, a little house, but the connection to the internet, a little globe, had a big red X on it. THEY KEPT IGNORING THE QUESTION. In retrospect I believe I was asking the correct question.
The only other mystery is how it all went wrong when it had once been working. I now believe that the router had been set up with the PPoE connection originally. That I'd done that with the help of a Support Tech when I first got the router, but was just following directions. It all was 'Greek' to me. What I don't understand is how it got knocked out later though.
