Issues with Bridging

Alright I've been working on setting up a small minecraft server that me and my friends can play on.
After doing a vast amount of research some of which included pulling out my hair.
I proceeded to do the following.

1. Bridge the Modem to my Linksys Router.
2. Set up a Static IP Address
3. Port forwarded port 25565.

and it all worked I was successfully able to start the server and have my friends over the world connect to me.
However when I woke up today the modem / router bugged out, being a computer tech and knowing only what I just taught myself about this.
What can be the problem for me? I tried power cycling the modem and router about eight times but in the end both the router and the modem have to be reset.

The Modem is a Embarq 660
The Router is a Linksys WRT54GS (with Speed Booster.)

I also noticed on my main desktop none of this worked at all with my killer 2100, I had a spare computer laying around so I have been using that.
It seems in this situation the killer 2100 is all but completely useless.

Thanks for your input.
