2.  Transfer the settings to the networked computer. On the computer you want to add i.e, the slave. RightClick the WiFi Icon, choose Properties, or find Network Connections/Wireless Network Connection/Properties/Internet Protocol[TCP-IP]/Properties – The Default Gateway and the Subnet Mask settimgs must as identical, and the IP address different. E.G. If your server was IP address was set to 192.168.0.1, then the slave should be set to 192.168..0.2

Can't Logon to Internet

Sunday, November 4th, 2007

One of the most maddening things that beset us is when we change something on a network and one computer can’t log on to the Internet. The machines can ping each other and can exchange network files, but one machine cannot log on to the net.

There are various things like, “simple sharing”, settings that can cause this, but given that it all worked before, why does it stop working now?

A very common (and really hard to find) reason is that the Winsock entry in the registry gets corrupted. This can easily happen when using spy-ware detection programs like AdAware, for instance.

The cure is really easy. Google for and download Winsockxpfix.exe from the net and run it. It will restore the registry network entries and instantly solve the problem. Do it if you encounter connection problems after removing network related software, spyware or after registry clean-up, or you can try this link 1.4MB Download.

I keep a copy of this on my “emergency” USB pen-drive, along with a few other essential and useful utilities.

Sharing Internet Connections

Tuesday, March 27th, 2007

Sharing Internet Connections.
Have you ever needed to network an extra computer, but one is on LAN and the other on WiFi?
When you go to turn on Internet Sharing on the second connection, the option to do so is not there.

Create a Network Bridge
The cure is quite easy. Open your Network Connections dialog on the Host machine, Turn off your existing internet sharing, and Create a bridge between the LAN and the WAN (Wireless Network Connection).

To do this, select (Shift/RClick) both the WAN and the LAN and select Create Bridge. When the bridge is complete, turn Sharing back on on your ADSL connection. All three machines can now surf simultaneously.

Typical Microsoft inconsistancy: Windows requires the Host on the network to be configured as IP Address: 192.168.0.1 and Mask 255.255.255.0 which leaves the Default Gateway as 192.168.0.1 – but when you add the Network Bridge, it stupidly defaults back to “Obtain an IP Adress Automatically” which won’t work. So you need to manually enter the IP Address, etc. on the Host Network Bridge “Internet Protocol (TCP/IP) Properties” dialog when you have got the Bridge set up.
