(add small 4 port hub) from cable router out to hub port 1.-take cat5 from central insert in port 2 of hub.- insert cat5 in port 3 of hub then other end in now open cat5 port

I guess you have a single incoming internet connection and wish it to be shared.

You only require one DSL / Cable router. To share this connectivity you will need Ethernet / Cat5 or wireless.

An ethernet switch or hub will enable you to extend connectivity.

All cable should be CAT5e or CAT6.
Suggest you consider the slightly more expensive switches that have auto-uplink. The negates the need of crossover cables.

Your better bet is a wireless access point. It plugs into your router and can be configured to be transparent to the network so that any IP address you get for your wireless device comes from the original router (better for networking).

At the blinkingly fast speeds of your Wireless internet, "N" is a waste. Get the "G". Here's a link to the product I would use...it runs about $50. http://www.tplink.com/products/product_des.asp?id=116

Unplug your power from the modem first and after that unplug your power to your router, disconnect all your cat5 cables and wait for at least 20 secs. After 20 secs or so go ahead and plug your power back to your modem and wait until all the flashing green lights are solid and that the link light starts blinking. After that plug in your Routers power (You can also reboot your PC while this is going on) . Wait until all blinking lights becomes steady then re-connect your cat5 from the modem to your routers uplink and last the cat5 cable from the router to your PC. If you'd rather not test the direct connection then go ahead and switch your wireless on.

Your wireless connection properties on your PC under "Internet Protocol TCP/IP" should be set to "Obtain IP address automatically" and that "Obtain DNS server address automatically" should also be set. Your routers should, if not already, be set to automatic DHCP. Make sure that on your Device Manager > Network Adapters that your wireless network adapter is not disabled and that it has the correct driver (yellow exclamation on it indicates it needs correct driver). You should disable your integrated ethernet LAN card if you have enabled your wireless Network Adapter to avoid conflict.

On your Wireless Network Connection properties under "Wireless Network" tab go to "Preferred networks" and highlight your wireless network name (SSID) . After highlighting click on the "Advanced" button and select "Access Point (infrastructure only) networks only"

You may have to reboot your PC and try to connect again.
If you have "Viewed all available networks" and tried to connect to your Wireless network but cannot what kind of error message are you getting ?

To quickly find out if you have Internet Connectivity coming in at all from your Internet Service Provider turn off your wireless switch on your laptop and try to connect a cat5 directly from your PC ( connect cat5 cable to what looks like a slightly larger telephone jack on the side or back of your laptop) to the back of your router and see if you browse the internet. You may have to reset your router (unplug and plug)

Try plugging the 3 that are not connecting using cat5 and the other 3 wireless

Router setup
If you are using the cd that comes with the router, that is the problem. You do not have to use the cd. Go to the control panel and un-install the program that the cd installed.
then:
Connect the Cat5 cable from the modem to the WAN port on the router. Then connect a Cat5 cable from any port on the router to your PC's network port.


Shutdown your PC. Unplug the power from the router and the cable modem.
Wait 30 sec. then plug in the power to the cable modem, wait 30 sec. then plug the power to the router. Wait till you have "Internet" light then restart your PC. The PC should pick up an IP address and you should be able to get on-line. This is if you have a cable service provider. If you have DSL, the router needs to be configured with PPOe.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.

It is hard to tell from here with the amount of detail supplied but here goes...
There are a number of things that could cause this:
1) Modem does not realize that the router is plugged in and has not given it an IP Address. Unplug the power to the modem and the router. Wait 60 secs and plug in the modem, wait another 60 secs and turn on the router, 60 seconds after this boot up your computer.
2) Some ISPs record the MAC addresses of the device connected, if this is the case you need to dig ot the router manual (page 53), go into the management console and have the router clone the MAC address.
3) Miswired. It should be ISP cable to modem, cat5 from modem to the WAN port on the router and then a cat5 cable from any of the ports labeled 1,2,3,4 to the computer. In your setup do NOT use the uplink.
4) Misconfigured router. Reset the router back to factory default by inserting a paperclip into the tiny reset switch located in the front panel.
5) Defective router or cable.

Sounds like you are setup to use Internet Connection Sharing. don't do this. Have each computer connect to the internet via the router. If the router is wireless connect all computers wirelessly to the router that are wireless capable and any computers that are not wireless capable, connect them to the router via a cat5 cable to the cat5 ports on the router. This will solve your problem. BPCS
