I have an Acer Aspire 5100 running on Windows Vista Home Premium edition. My only option for internet wired ethernet but i have some other gadgets that i would like to connect to the internet wirelessly. I tried to share my connection but with no success. Can anybody give a sort of a tutorial on how to set up a shared internet network?
Before anybody says it i can't use router. It's not an option I have.
Setting up ICS in Vista isn't really very different from XP. However, if your Router has an IP address of 192.168.0.1 you will have to change it to a different Subnet so that it doesn't conflict with ICS which *MUST* allocate 192.168.0.1 to the "host" PC's network adapter that connects with the "client".
If you have this conflict, which might be the cause of the error, change the router's IP address to, for example, 192.168.1.1
How are you connecting to the internet and what is the IP address of whichever "network adapter" you are connected to the internet with?
For example, if you are using a USB Modem, you will have the IP address allocated by the ISP. If you are connected via a Local Area Network of some form, you will have a LAN IP address using one of the address ranges reserved for local networks, most commonly a 192.168.x.x or 10.x.x.x address.
You are connecting via a LAN which uses the 192.168.0.0 Subnet and the Router's IP address is 192.168.0.1
This means you will be unable to set up "Internet Connection Sharing", because the adapter that connects to the ICS "client" must have the address 192.168.0.1 which will conflict with the router which already has this address.
Having said that, why are you not connecting all of your "computers" to that same LAN?
Connect a Wireless "Cable/DSL" router to the existing LAN connection and use the router's facility to *clone* the MAC address that's already registered with the landlord. You can then run your own Local Area Network and connect whatever you want to it.
As far as the landlord is concerned, there is a single device (whose MAC address he has) connected to his router. There isn't a problem running a "sub-router" connected to a main router. I actually have Cable broadband, but I regularly run a second Cable/DSL router connected to the first one.
