Common causes for not being able to share Wireless?

[bizzybody]

The setup.

Laptop with Windows Vista Ultimate SP1, connects to a WiFi router and can go anywhere on the net.

Router has IP address 192.168.0.1 cannot be changed, nothing on the router may be changed, no security on the router.

Laptop's wireless is set to get IP automatically, router typically assigns it 192.168.0.5

Go to properties on wireless, Sharing tab, check the box, click OK... about 30 seconds go by and "An error occurred while Internet Connection Sharing was being enabled."

What error?!?!?!? "WHAT IS YOUR MAJOR MALFUNCTION?!"

It would be very nice if "An error occurred while Internet Connection Sharing was being enabled." was "An error occurred while Internet Connection Sharing was being enabled due to..." followed by *exactly why it could not be enabled*.

Well i dont see why u want to use ics on wireless when you have a router. Any wireless device that has the router wep key will connect to the router and the internet if the router has your info. Doing it this way also means your lappy does not have to be on for others to connect. A ad hoc wireless network will let you share but you dont need the router and the host system must be on all the time. Maybe i did not understand what you are trying to do

The Win95 system doesn't have wireless.

I did find some forum posts that said if I created a bridge between the Wireless and Ethernet, then removed the Wireless from the bridge, it'd fix the problem of it refusing to enable sharing on the Wireless.

It did! BUT it still isn't actually sharing the wireless because it's still assigning the same IPV4 address to Vista's ethernet AND to the Windows 95 system. Still does it even after deleting the bridge.

I've never seen anything so problem-infested as Windows 2000 and later networking! (Especially when any two or more different versions of Windows are involved.) Whenever I do get a setup working, it never stays working. Any change anywhere turns a network into a NYET-work.

Well, considering Internet Connection Sharing automatically tries to use the same subnet to dole out IPs, I think changing your internal subnet to something different might help quite a bit, perhaps 172.16.0.x or 10.0.0.x (both /24, of course).
