ICS Not Working

Here is my setup:

Wireless Connection -> Laptop
Laptop -> Router
Desktop -> Router

I am trying to get the desktop to use the internet connection from the wireless, through the laptop, but I am having a lot of difficulty getting it to work.

When I enable ICS on the laptop it creates a network called Network, and it appears that the desktop connects to this, but it says "No Internet Access" and I can't figure out what I am doing wrong. I have read the official Microsoft ICS instructions and several other tutorials and I'm not sure what the problem is. Has anyone set up an ICS this way before?

Hello machinus,
Normally ICS is used with a wired connection. I'm not sure why you need to use ICS if you have a router but if you want to share a wireless connection it's usually required to turn the wireless machine into a wireless hotspot by using a third party program called connectify. :)

Connectify - Turn your Windows 7 laptop into a Wi-Fi Hotspot

I have two routers and I'm just using the second one as a "hub" because the ICS instructions say to do so. I could just plug it in directly to the desktop which is what I am doing.

I need ICS because the wireless is too far for the desktop adapter to pick up but I can use the laptop to connect both. I have had it working intermittently but the instructions I have read on various forums seem split between static IP and DHCP. I have had unreliable success with both and am not sure the standard procedure for:

Wireless Connection -> Wireless Card in Laptop -> CAT 5 -> NIC In Desktop

At the moment I am using double DHCP without any ip specification and I am worried this will cause IP conflicts, but static IP seems to fail after only a few minutes or not connect at all.

Double DHCP will usually cause problems, in fact dual router set ups aren't exactly a supported configuration so might not work very reliably for you.

I would try using a regular switch instead and see if you can get it working that way.
