Check that "Internet Connection Sharing" is still enabled in the Host PC. In the Network Connections folder, right click the actual internet connection (modem connection), select Properties then the Advanced tab. The box should still be ticked for "Allow other users...etc".

Then check that the Wireless Network Connection still has the IP address 192.168.0.1 by highlighting it and looking at the bottom of the panel at the left:



Now, in both PCs, remove the existing wireless profiles. Right click the Wireless Network Connection, select Properties and then the Wireless Networks tab. Highlight the existing Ad Hoc network and click the Remove button:



Go through the procedure again to set up an Ad Hoc Wireless Network per this tutorial.

Phew! Got there after an hour and 3/4! Followed everything to the letter but it still didn't want to work; fiddled around with some of the windows help suggestions and somehow got there in the end. Somehow after disconnecting and reconnecting the broadband and then changing the wireless connection name (just removed the number 4 from the end) - it all kicked into action.

Thank you once again Mike, very much appreciated.

It's gone again. Worked for about 2 hours and then went. Have checked all settings and can't see anything wrong. Something different this time though: the client can see the host pc but can't access it, no internet connection either. The host cannot see the client.

Please could you suggest something else I can try?

I'm struggling a bit to see the reason why it should now start to misbehave. Do both of the Wireless Network Connections have their correct IP addresses? The Host should have 192.168.0.1 manually configured (by Windows when ICS was enabled) and the Client should have an address between 192.168.0.2 and 192.168.0.254 by DHCP.

Also, is it possible that firewall software is blocking your network access?

I've sent you a pm to say I've sent you some screenshots via email! Don't know that it's the right email address though?

Have just noticed though that my clients IP is 169.254.95.294 - that's well wrong then! Hopefully that will tell you what I should do next? - you don't have the smilie for praying so I'll just type it. :pray:

Screenshots have now arrived. I don't know what name you gave to the Ad Hoc network when you set it up, but the Client computer is connecting to a network with the name WLAN_AP which I wouldn't have thought was your network.

If this is the case, in the Client computer "Remove" the profiles for all networks [instructions] and then set up the Ad Hoc network again from scratch per the first part of the tutorial [here]

Yes the ad hoc network is called WLAN_AP, it was what the original software called it so I stuck with it.

DM

OK but, in any case, I'd suggest removing the existing profile in both computers and then setting up the Ad Hoc wireless network again from scratch with a different name, so as to force Windows not to use old settings.

Can I just "butt" in and point out that the wireless connection name was changed:

Could this have caused problems Mike? ...... obviously your advice of deleting existing PROFILE and starting over would take care of that.

Sorry for posting in the middle of your support thread but I am following with interest.

Yeah I was thinking perhaps that's what was meant, ie; Network Connection 4 .... anyway thanks for your thoughts on that, I don't want to steer things off course.
