Ethernet Hub -- How do they work?

macnext1 · #1 Apr 23, 2008, 03:12 AM

According to the reading I have done, an Ethernet hub is basically a signal splitter. It takes a signal coming in on any port and broadcasts it to all the other hubs. That is why computers hooked up to a hub have to be able to handle collisions. I don't have multiple computers; I have 2 modems, 1 satellite and 1 DSL. I would like to hook my computer and both modems up an Ethernet Hub. I would then power one of the modems off so I would basically just have a feed-through from my computer to the hub to the modem and out to the world. Thoughts? Suggestions? Help? Thanks for whatever thoughts you may have on this topic.

Auto MI-DX (I forget the acronym) ports automatically determine if the pairs used for transmit and recieve.

What I'm trying to achieve is to be able (easily) to switch from one modem (ISP) to another. I tried using a splitter (RJ45?) but I still have to disconnect one or the other, I can't just leave them plugged in and power off the one I don't want. That is what I would like to be able to do (getting too stiff in the joints to enjoy crawling under the desk). Since a hub as you describe it sounds like it might repower the signal perhaps that would work. What do yawl think?

What you can do is get yourself some software that allows multiple Ethernet configurations or two Ethernet cards.

Configure the systems (Satelite, DSL) with different gateways. Configure the connections in Windows with the gateways. When you select the appropriate connection, the gateway determines the route.

I've never seen a Satelite modem, so I don't know if it would work. This would work if you had a DSL and cable modem.
