[Streamyx] Need help with PPPoE &BT, Bridged settings, dead mode

I got my 1.0Mbps connection yesterday and I fiddled with it, and screwed up my connection in the process. So, I, um, need helps guys.

1) Dead Modem
I have a 'dead' modem. It's a Riger DB102, and only its Power and PC LEDs are lighting up. The Link and Data LEDs are off. There's no way for me to test the Data light without getting online in the first place, so I'll leave it alone. But, the Link light is supposed to light up when the modem is powered up. (FYI, I'm running on a different modem using the same Streamyx account to post this.)

I am also unable to get into the router's webpage (192.168.1.1).

All this happened happened right after I rebooted the modem into PPPoE mode. Previously, I had rebooted the modem quite a few times, switching from PPPoE to Bridged modes to test out settings, and I had no problems.

Resetting the modem didn't help, unless there's more to resetting than just pressing the button in the tiny hole behind the modem that has 'Reset' written above it.

2) Abysmal BT speeds with PPPoE
This was the major reason I kept playing with the modem. It seems like PPPoE mode gives me around 2~4kbps instead of the high 80~100kbps download speed I get with the default Bridged connection.

Switching the modem to an Aztech DSL600EU sorta helped. Sometimes, the speed is still as sluggish as ever. Sometimes, I get a boost to 14~15kbps. Oh wait, I just checked, it's now in 30~40kbps region. All of a sudden, uTorrent found peers and seeds for my torrents. For 44 minutes before that, most torrents were Seeds 0(0) and Peers 0(0).

3) PPPoE connection likes to die...
...in a way. When running in PPPoE mode, after a period of surfing, the connection will become sluggish suddenly. Then, I can't even load webpages. I have to reconnect every single time this happens. BTW, it's a DB102 problem. I've yet to experience it on my Aztech (but I've never used the Aztech with this account until today).

On Bridged connections, the speed is fast and the connections do not taper out and die.
