I got a following situation: Win7 PC without Wifi Adapter and a WinXp notebook with Wifi network access. I've tried setting ICS on the notebook, having both computers connected with an ethernet cable, still it's not working, most probably because of conflicting IP: the notebook has 192.168.0.X in the Wifi network and ICS sets its LAN address to

Is there a simple alternative to ICS for WinXp? If I only could set address pool for the LAN to eg. 192.168.1.X then maybe it could start working.

You could...

  • configure the router to use a different Internal IP range... like eliminating any potential conflict.

  • ensure you are using a crossover cable to connect the computers together, since your laptop may not have a new enough ethernet card in it to automatically make that conversion. Some will insist that all NICs since 2000 are auto-sensing, but this doesn't actually prove to be the case in every instance. Of course, you can test this yourself, by manually setting the ethernet cards in both the laptop and desktop to an internal IP address in the same range, and see if you can swap files. If you can, you don't need a crossover cable.

But, a simple alternative to ICS, is a router.

The Microsoft article that is supposed to allow for a registry setting change, doesn't actually apply to Windows XP and above. But, apparently it's simpler to alter the range. Once it is set up, go into the TCP/IP settings of the network adapter that is now supposed to be the gateway for ICS. It's IP address has been manually set to Just change this to whatver range you want... say DHCP won't work, but then you just manually set the address on the Win7 computer to be

I got a "somehow" limited access to the router and modifying its settings is a last resort. – soliloquyy May 12 '12 at 19:21

Found this article before, but it is really meant for newer Windows, there's no ICSsharing registry key in XP – soliloquyy May 12 '12 at 19:28
It's actually meant for older versions, as I also found out. But... I edited again to reflect what appears to be a simple method of making this all work – Bon Gart May 12 '12 at 19:39
seems it started to work, thank you. Damn, it was so simple. – soliloquyy May 12 '12 at 20:41
