Client will not connect wirelessly through Host to InternetHi Guys Some help would be much appreciated indeed........ The Setup: Computer 2 - connected to modem/router via Ethernet - no probs connecting to internet. Computer 3 - connected to Computer 2 via wireless card (same manufacturer wireless card in both C2 and C3). Problem: C2 is designated as the HOST C2 connects to C3 and file sharing is working - but no matter what I try I cannot get C3 to get "through" (for lack of a better word) C2 and onto the internet. Windows Firewall is currently disabled - IP Addresse setting is automatic - C2 (i.e. HOST) computer displays wireless tab under Network Connections as "Shared" - but there is no "Enabled" word alongside this, which I believe should also be present (?). Is this correct (i.e. should "Enabled" also be present), and if "Enabled" is not present is this the problem (or is it something else) and how do I sort this out. Likewise, on C3 I am understood to believe that the corrsponding wireless tab should display the word(s) "Internet Gateway" or something very similar -but is not. Should it display these, or similar words, and, is this the problem. In short: on which computer is the problem (i.e. the Host or Client), and not withstanding my observations as described above (reliavnt or not (?)), what the hell do I do to correct it - its driving me mad. Clearly been able to access access C2 from C3 wirelessly does not also automatically mean C3 is going to be able to access the internet through C2. Thanks in advance |

Internet Connection Sharing

My first recommendation is to get a router that has a wireless connection in addition to the wired Ethernet, and use only that to connect to the Internet. One reason for this is that you are trying to set up a cascaded NAT (Network Address Translation) scheme, which is less than optimal and not really a good idea.
If you insist, the Internet connection of C2, i.e. its connection to the router, needs to be set to shared, not the wireless connection. The wireless connection will then assume the IP address 192.168.0.1, which means that the router must not be set to use the 192.168.0.x net. It needs to be set for a different net, for example, one of the Class C nets 192.168.1.x or 192.168.2.x, etc.
Thanxs - and yes, you were

Thanxs - and yes, you were bang on the mark! - the problem revolved around sharing the wireless connection, which was not the connection that had to be shared. Indeed, it was the ethernet link that should be shared.
I changed that one parameter and the internet connection worked immediatly. I dont know about the Ip address settings - I have left them all on "auto detect", sp how any changes there would impact on the connection I don't know.
Many Thanks indeed.
You're welcome

Good that it works now. You were lucky in that the router doesn't use the 192.168.0.x net by default, otherwise it wouldn't have worked.
It's still a good idea to either swap the router or buy an Ethernet wireless access point and plug it into the router. One advantage would be that C3 could get to the Internet when C2 isn't running. Another would be to avoid the cascaded Network Address Translation, which now happens twice—once in the router and once in C2, which is now also a router.
I would also recommend to re-enable the software firewall and allow only the types of connections that you actually use. The NAT (Network Address Translation) in the router protects you to some extent, but in my view that's not safe enough.
