I have a Belkin 4port router and a Netgear 8 port switch that I want to use to share and cable modem internet connection with at least 9 computers. I can get the router to work just fine by connecting computers directly to it, but have not had luck connecting them thru the switch and router. I need to know how to configure the computers that are connected thru the switch.

>but have not had luck connecting them thru the switch and router
You just need the right cable, as described above, or to use the uplink port (also described above). It sounds like you have everything else squared away already.
If you want to build a crossover cable yourself, I can tell you how (but there are many, better references on the net).

How to troubleshoot this sort of connection.
Step 1. Verify DHCP services running on Router(also verify there are enough ips for all the computers.)
Step 2. Verify PC connected directly to router functions
Step 3. Connect onswitch[uplink(with strait-through) regular port with Crossover Cable]. to your router
Step 4. If 10/100 Light is green on either end you have a 10Base-T connection.
If you have a Orange light you have a 100Base-T connection.(check hardware documentation for light configuration. and status colors)
Step 5. If you have no light its either a bad cable/Switch/router port. Again check hardware documentaion, for thier light config.
Step 6. Connect a PC to the switch using a strait-through cable, Verify you have a physical connection with lights.
Step 7. Set computer to DHCP, Attempt to obtain a lease with winipcfg or ipconfig(win2K,WinXP,WinNT
Step 8. If you can optain a lease try to ping some IP on the internet, Go to start Menu-->run, type CMD or command for older windows stuff, type "ping www.yahoo.com" If it says unable to resolve host or cannot find host, or something you are having DNS issues. Try to ping 192.168.1.1 or whatever the gateway on your router port is. If you can ping that IP your requests are hitting the router and getting past the switch, If your other computers can connect just fine through the router is a PC issue, try another one. Also if something wierd happens like this, verify that the computer hooked up behind the switch has the same DNS servers as the other computers hooked up to the router. If it says Request Timed out 4 times, but it says something like
"Pinging www.yahoo.adadns.net {66.218.71.88} with 32 bytes of data", it resolved the DNS just fine, meaning your computer is getting multicast requests out to thier server just fine, If this computer cannot connect but your others behind the router can its PC issue. Just for fun do a tracert www.yahoo.com to see where it dies.
Next up
If you cannot get an IP lease and get a 168.245.blah.blah, this means your computer was unable to get a DHCP lease for whatever reason.
Staticly put a IP into this computer that is on your subnet
EX COMP config
Default gateway:192.168.1.1<-- whatever your router port is
Subnetmask:255.255.255.0 otherwise knowen as a /24
IP:192.168.1.50<-- or some other IP not in use on your network.
DNS servers= whatever they are inside your router or other comps hooked up behind the router, you may need to write these down,
Try to ping 192.168.1.1<--Router gateway
IF reply = yes Then
Response = COOL!! we can ping to other side of the switch
Else
Response = ****!!
End ahh screw it
Okay if you cant ping to the other side with this ip check the arp table, arp -a for windows. will tell you what your computer is arping to. If you can see the router in here but you cannot ping it, either dump your TCP/IP stack and rebuild it or reload windows.
Whew, almost there
Okay i'm getting tired of typing now, HOpe I gave you a few more things to try,,,
Have fun,
Also as a last resort RTFM!!!!!!

You will need to do one of the following:
1) Use a cross-over cable to connect the Modem to the router (thus sacrificing one of the ports)
2) or altenately, if you have an uplink port on the router, then use a regular CAT-5 cable and connect your modem to the uplink port.
You will then need to connect to the router and configure the connections in the setup page, of which I will not be able to help since I don't remember the exact pages.
As to connecting your switch, use the same steps above to connect it.
When you are done, you should have the following:
Switch Uplink Port -> Router Port, Router Uplink Port -> Modem
-or-
Switch Port -> Router Port, Router Port -> Modem
You will then be able to connect all your computers to all the empty ports on both the switch and router and have them all get on the net.
Do make sure that you either have DHCP enabled on the Router, or configure your IP addresses manually for all the computers so they will be on the same subnet as the internal LAN IP of the Router.
Hope this helps.
