Hub / wall connections

You may need to get a router. The cable modem may not be giving more than 1 IP address.

A router would fix that.

Because the cox cable modem will only bind to one mac address (computer). You need to purchase a router, any router linksys, dlink, will do, get a wireless one so you can setup wifi as well. Plug your cox cable modem into the wan port on the router, plug your pc into one of the ethernet switch ports, you can use your web browser IE to login to the router and secure your wifi signal, power cycle your modem to make it bind to the new router. Most linksys dlink are programmed for a class c network, you could in theory put 254 devices, computers on your connection now.

Connect the power supply.
connect the ethernet cable from your router (or the box that your isp gave you to get the internet connection) to the port labeled "Uplink" on the hub.
Connect the ethernet cable from your computer or another device to be connected to any of the ports 1 to 4. Do not use port 5 (that port is used to "chain" another hub)
Please be aware that a network hub is basically a very simple device that will not assign an internal ip number to your devices or computer, and if you have two or more devices or computers, you do need that either your "modem" (the device that is installed by your isp) is capable of handling more than one computer, or you will also need something to act as a router (your computer can do it, but you will need to know how to set up that).
Hope it helps

Connect your modem/router to one switch's port. Connect your PC to the rest ports.

have you tried simply disconnecting the router from its power and data source, remove the power source from the modem, connect the router back to the modem,(with all the systems allready connected to the router), restore power to the router, then finaly restore power to the modem. after a few min the router should automatically sense multiple requests for dns and ip services and asign addressess accordingly.

If that makes no diff, watch the led light on the router that corresponds to the port that the non-functioning system is docked with. when attempting to access the internet, does the led blink? if it blinks fast and you also see that the "modem link" is flashing then there is a connection, and any lack of access to the internet has to be a firewall setting.

simply go into your router settings by typing 192.168.1.1 in your web browser and using "admin" as the username and leave the password blank(that is unless you have changed all that)
you should be able to view all the computers currently active on your network and the ip assigned to them. you may see that port 5 has been restricted, in which case the easiest way from the very beginning would have been to simply take a ball point pen and hit the reset button on the back of the router.
on the other hand, try that first then the other options above as you may save yourself lots of time and headache

GOOD LUCK!!!

p.s. dont forget to rate this post!! :D

First, FYI, I hope you mean Switch and not Hub and I am to assume your Router's LAN ports are all in use as to why you want or need the 5 port Switch and that you have Wireless Access Points or maybe your Router is a Wireless Router.
Next, you have to connect your 5 port Switch to your Router LAN port. Next you need a Wireless Access Point device to plug into your 5 port Switch. It would be helpfull that all your devices are of the same name brand also.
Now you have a Wireless network.

Disable DHCP in the router. Connect the modem to a LAN jack on the router. You'll have 3 LAN ports. If you need more ports, buy a hub. (You can change the default IP address on the Linksys, but you can't forward through 2 NATs.)

Hi Tman,

Here is a link to the Xbox ports. http://support.microsoft.com/kb/908874
In the firewall option, direct those ports to the IP of your Xbox. I don't have an xbox, but I would think there is someway to set a static IP on it. That way DHCP won't change your xbox ip when you reboot it. Some routers allow you to assign a specific IP to the xbox, but not sure about yours.
Visit this site, http://portforward.com/routers.htm It may have your router, and will tell you how to setup the ports for your xbox step by step.

Sounds like you may need what is called a "Crossover Cable' connecting your router to your hub, or if either device has an uplink port, use it on one device to connect to normal port on other device. Here are instructions for making your own cables: http://www.lanshack.com/make-cat5E.aspx
