Internet sharing wifi and USb solved

How should I bridge or share the internet between these two networks ?

Bridging usually works best for ICS.

Here's a checklist of things for ICS and file sharing for 2 croslinked computers (in my case a Windows 7 and XP one):

- both computers set to the same workgroup
- restarts
- advanced sharing settings - all things turned on (network discovery etc.) except for password protected sharing
- bridged the connection with the internet
- turned on Internet Connection Sharing for the internet connection - this forced an ip to the other connection (192.168.137.1) and gave an option to select which connection should have access to the ICS (the second connection or the bridge - you choose the second / crosslinked cable connection)
- shared some folders on both computers
- worked instantly (the other pc aquired a correct ip and internet)

Using ICS (Internet Connection Sharing)

Notice how in the link above they use a switch to connect more than one computer to the ICS machine.

The way you are doing it may not work correctly because you are daisy chaining the ICS machines end to end.

How this looks


ANd look at this one. It starts from just next to my server laptop, Signal is -19,. when connect it from a crowed store room the signal drops to -50. It's around 65 when I put it behind a thick steel cabinet. It again raises to -25 when put it at 5 fts to the server laptop.

Now again I'm having problem with this network. As you can see it is obtaining wrong ip

I tried to renew the ip and this is what I got

C:\Documents and Settings\compname>ipconfig /renew

Windows IP Configuration

No operation can be performed on Local Area Connection 3 while it has its media
disconnected.
An error occurred while renewing interface Wireless Network Connection : unable
to contact your DHCP server. Request has timed out.

Tried it again with both ether and wifi on

C:\Documents and Settings\compname>ipconfig /renew

Windows IP Configuration

An error occurred while renewing interface Wireless Network Connection : unable
to contact your DHCP server. Request has timed out.

I connected in Fedora (linux), working fine with this result. 10.42.43.1 for the host and 10.42.43.10 for the client running windows xp.

This time bridging solved the problem. Hopefully it carries on. One questions remain how can you enable ICS and bridging on the same connection at same time ? I bridged my Internet connection and wifi adapter. And it working now.
