    To connect a pc to a router I need a cross over cable. What do I need to connect a router to a switch - cross over or straight through? I will be using cat5e cable

    Many thanks

    Unless you are connecting a Computer to the Internet port or WAN on a Router you use a Straight-Through Cable. If you are connecting to a Hub, either a Straight-Through Cable to the port that supports Uplink, or a cross-over cable to any port.

    I am wanting to use a switch as my router doesn't have enough ethernet ports for my network so I need to have more ports so a cross over cable from router to switch should be ok? right?:)

    Yes a crossover cable will work for you. It may very well not be necessary, as the ports on many modern switches autosense and adapt to the correct transmit/receive orientation. If they do autosense, you will still be OK.

    Haven't seen or used a crossover in almost a decade, and the odds you have a device that requires one is on the order of a billion to one.

    Hubs are rare now too. Pretty much anything mainstream you buy with multiple ethernet ports is a switch now.

    Hubs = dumb, low capacity. Switch = more intelligent ethernet transmittion. Used to be a big difference in price, but switches are very cheap. If you're getting something *really* cheap, check it's a switch, not a hub.

    Ditto, pretty much anything mainstream that deals with ethernet has auto-sensing ports on it, meaning you don't need to worry about cross-over vs straight-through. Again, auto-sense should be on the list of features.
