I have a fractional T1 connection coming into my home. The way that my network is setup right now has my servers and Linksy routers connected into an Intel switch and from the switch to the T1. However, I am wanting to redesign the network (eliminate old/useless equipment and add some new stuff) by taking a BEFW11S4 router straight into the T1 and then having the switch and everything else plug into the router. I have been trying all day to make this happen but no matter what I do I can't get anything to connect to the internet when I have the router straight into the T1. Everything works fine when everything goes through the switch to the T1, but not with the router. Is there anything that could be causing this problem? I have all of my business information stored on servers and I can't risk having them offline for very long, so I can't simply unplug everything and figure this out the hard way. Thanks.

I'm missing something here, perhaps you can fill in the gap.

You say when you connect direct to your T it's fine. OK, where are your PC's/server getting IP addresses from? Is that switch really a switch? Something between you and the internet holds an IP address...possibly static. If true, your Linksys needs to be aware of that and act accordingly. More details please.

Before we had the router, I had one IP address that I was allotted between my four computers, so it leads me to believe that the servers each have their own IP address. That's why they go into a switch and don't need a router. The switch is an Intel InBusiness 10/100 8 Port Switch. And unfortunately, I can't get into the servers; a man set them up a few years ago and recently he literally just kinda...moved away and got in some legal trouble. So now he has the passwords to the servers and I can't get in contact with him. Anyways, this is the switch I have: http://www.hardware-one.com/reviews.asp?aid=208&page=1.
There's a box (dunno the name of it) that takes the T1's fiber lines and outputs it as ethernet, then the switch plugs into it. I don't know how much translation goes on within it.

Ok, I'm just trying to figure out where your 'routing' is coming from...could it be one of those servers, or are they all assigned a static from your ISP (which is unusual)? Does your PC use DHCP or is it a static address?

Also, you should try to get the server passwords back. I know it's a pain but you will need them eventually unless you want to bypass them or reinstall.

But if it all works from the switch, why do you want to add a router? What is this 'box' exactly? Could it be a router or just a CSU/DSU?

There is a Cisco AS5200 that definitely has a T1 input in it, and it seems that we lose all connectivity when it's down. I don't know what the AS5200 is, though, so I don't know what it does or why it has to be up for us to get access.

Yeah, I kinda figured since that's a required piece. Hmm...without knowing anything more, I would contact your ISP (the folks you send your check to for the T1) and find out how they are providing you an IP, then ask them if your router will support being attached directly to your CSU/DSU.

The only routers i've seen with CSU/DSU have been upwards of $400. But what about this Xincom model? It claims that "The XC-DPG402 has two WAN ports that allow you to connect two broadband connections of any type, including Cable, DSL and/or T1..."

I could not say for certain that brand will work or not...beyond my ken.

What I can say for certain is that 2 routers won't work together unless you tell them to, as I still suspect you have one, either in-house or beyond your demarcation (ISP controlled). If that's true, you would need to tell your linksys router to "make nice" with the other one by telling it use static IP (passthrough) or PPPoE or something else, etc. Contact your ISP.

Well, if the above router would work I could get a WAP instead of the wireless router. IF it would work, that is. Again, if it would work, it's the cheapest solution i've found.
