I'm working on a coop project and what im trying todo is connect this desktop pc to the schools wifi using the wireless card then using the LAN port to a router to allow connection of more wireless devices (using a different SSID and password).

I have enabled sharing on the wifi card (ICS) and set up the router to broadcast the new SSID but when you connect there is still no internet. I have tried plugging my laptop into the LAN port of the pc but that also doesn't work.

If anyone could point me in the right direction that would be awesome I don't want to use any 3rd party software
also when I enable ICS I don't get any drop down box I seen in one tutorial that they had a drop box could this be the problem?

That's what the ICS does though. The ICS PC should be connected to a LAN port on the router, DHCP turned off, and assigned a static IP outside of the range of IP's that ICS will hand out but still in the same subnet.

IE.

If ICS is using 192.168.2.100-192.168.2.255 and that PC has an ICS IP of 192.168.2.1 then set the router to 192.168.2.2 so you can then access the router settings still.

Did you give the router a static IP address in the range of the ICS network and turn off the routers DHCP ?

When you enable ICS, you are basically turning your PC into a mini router that you could plug into a network switch and it would hand out IP's and have it own routing ability. Adding a router, but not turning off it's routing features will create a conflict.

I did not turn off the routers dhcp because it will be random people connecting to it so shouldn't it still need to dish out ip's to them?

Didn't mean to make that the solution but the ICS is through a wifi card that's connected wirelessly then I want the lan port that is wired to a router to hand out so you're saying I should put the router into the same ip range as the wifi card?

No.

Internet comes in from WIFI to the PC. then you enabled ICS to share that WIFI connection over the LAN port right?

By defaut I think ICS using 192.168.137.1 for the PC, then .2 .3 .4 etc it hands out because it acts as a DHCP server. You need to find out that range first, and then go from there.

Is this actually part of the coop project itself?

Yes that's how its set up and yes im setting this up then im going to have a web page redirect with my entire project on it

And so if the wifi card is using 172.16.32.51 I should set up the lan that is currently 169.254.189.146 to 172.16.32.52 then router to 172.16.32.53?

Why not just put your webpage with your project online and let whoever connect to the schools wifi itself. I don't see why you are setting up a whole network to access internet when tehre is already internet there.

And no, forget about the WIFI's ip. It's like an external IP and has nothing to do with anything. Windows ICS has made it's own IP and DHCP server and that is what you need to be concerned with.

I'm doing it to show part of what I have learnt and an example of some stuff I do at coop most things I do don't goto that extent but I have to make it look good and interesting and so I will set up the router to 169.254.189.147 since the lan is 169.254.189.146

If the LAN starts at 147, don't put the router there or Windows will try to give .147 to the first WIFI device connected to the router. Give the router like .254 instead, since most DHCP starts and goes up by ones, so if the LAN starts at 146, then the WIFI devices will get 147, 148, 149, etc, so using 254 it should be safe and out of range.

I still cant figure this out, I think I may also be using the wrong ip now to since the lan port dosnt have a default gateway ip ive been using the ipv4 so I have to find that ip I assume? then when I have it ill log into the router with another laptop and change it to a static ip about 30 above it? so like lan 192.168.1.1 router static 192.168.1.31?

Ah, forgot, direct PC to PC connections requires a crossover cable. It's a special LAN cable that has 2 pairs of wires crossed over.

What OS is the machine running ICS on, what version of windows? They have changed the range. We need to try to figure out what it should be handing out so we can try to config the router and get it working.

Ok, so that should be the IP range that ICS is handing out, providing we get the router configured or you had a crossover cable.

So on the router, set a static IP of 192.168.137.254 (don't reboot yet, and then turn off DHCP and then reboot the router). Don't worry about anything else like the wireless.

Then try plugging the ICS machine into the router with an ethernet cable into one of the routers LAN ports. Then plug your testing PC into another LAN port on the router after the router has fully booted up and see what IP the test machine gets and if it has internet.

So I went onto the laptop into the router and selected use static ip theres now 3 options under it: ip address , ip subnet mask and gateway ip so id assign subnet mask of 255.255.0.0 and gateway as 192.168.137.254?
