Plugging a switch into a router requires straight through cable?

[coolred]

So I needed to add some more ports to my share my internet with my PCs. I currently have a Linksys WRT54GS wirelss router. I purchased a linksys EZXS55W 5-port switch. I was surprised to find it didn't come with network cables. I could have swore the linksys hub I had years ago and my router both came with at least 1 cable. But anyways, I have the cable and tools and know how to make my own cables. Just wanted to be sure I made the correct kind of cable.

So I will be plugging 1 new PC into the switch and one that was already connected to my router. So I need a new straight through for the new PC to switch connection.Then to go from the uplink on the switch to an input on the router I need another straight through, correct?

Yes, as long as one of the devices is Autouplink or has an uplink port, you only need straight throughs.

However, if you didn't have either of those, if you know the EIA/TIA 568B wiring standard (white-orange, orange, etc) all you have to do to make a crossover cable is place the white-green and green wires (568A standard) in place of the white-orange and orange wires and leave the other side white-orange and orange first (568B standard).

Hope that made sense

CAT5e Straight or Crossover, what should I use? http://www.ezlan.net/faq.html#crossover

oops!

To keep it simple, I would just straight-through cables as long as you have an uplink or autouplink (also called MDX I believe) port on your switch or router. Most likely, you do.
I believe about all new routers/switches are capable of this. You are supposed to use a crossover for like devices, but as the article Jack linked states: "A lot of newer switches and Routers have MDX ports (look at your hardware Data Sheet), if such is the case it does not matter this type of port would adapt to the cable."

Yeah, most any modern router has auto uplink ports. Mine they are sensed automatically on all 4 ports, some it may only be a specific port. Check your documentation.

first of all, a SOHO Router with built in switch, is more switch then router (as far as connecting them together) so it's more like Switch->switch.

The rule of thumb is Like devices require crossing, different devices require straight. So switch to switch=cross, switch to client = straight.
