Wlan P2P internet connect nogo on system #2

Specs: Windows XP, 2.799 GHz / 959 MB
Need some help here please guys.

P2P Wireless Lan operating, PC1 OK but PC2 cannot reach the internet.

Works under the following conditions........
PC1 Tosh, has USB Vodaphone dongle/modem for local wireless internet provider, ethernet adaptor and also inbuilt wireless card for LAN use.

PC2 IQon also has ethernet adaptor and 802 G/B wireless add in card.
Both systems have Norton internet firewall with rules set to allow full comms between named systems. Both show up in network map.

Both systems fully functional with ethernet lan adaptors enabled, full file sharing both ways, both reach the internet ok.

Now disable ethernet, and enable wireless adaptors to make P2P wireless LAN.............
Both connect and associate, firewalled, IP good and the network LAN functions well via wireless cards for filesharing in both directions, PC1 can connect to the internet as normal.

However PC2 cannot see the internet.

Have used Networking wizard to set up PC! as internet interconnect with PC2 connecting via..., switched off firewalls, disabled and reenabled adaptors. Proxy off. Tried sing forced IP's...Comes up good for filesharing every time without fail, but never allows an internet connection on system #2.

Change over to Ethernet cable and adaptors, everything perfect, PC1 and PC2 both connect to the internet without fail.


Best Regards

Here's what I'd do....

First, setup in the working configuration and open a command prompt window (Start >> Run >> type cmd and hit Enter) on both computers and run the following command:

ipconfig /all

Compare output and save it to a text file (cilck on my name above in my response and read my "how-to" guide labelled, "Post the output of ipconfig (version 2)" for info on how to do that.

Next, setup in the non-working configuration and do the same. You'll notice in the working configuration the only thing that differs between the two is the actual IP address. Compare PC2's output to PC1, and report any differences back here to us.

I have to ask, why haven't you spend the $50 USD on a wireless capable SOHO Router and connected it to your internet? Once that's connected and working, you could configure a WLAN on it and connect your wireless clients to that and avoid the hassles you're having. Just a thought......

Hello William, thank you for your reply.

Um, $50, well, I live in the back end of beyond in a non recognised country, and getting things like that through customs attracts too much attention....actually the goods hardly ever arrive here in North Cyprus anyway having been filched somewhere along the line.

Will do the IPconfig bit as you suggest and see what it is doing, although I have set both systems up to have a static IP and DNS reference.

OK, something new....in desperation I just made a bridge on PC1 (the internet enabled one) and bridged together the ethernet adaptor and the on board wireless adaptor.

When I disabled both PC1 and PC2 ethernet adaptors and took the cable out, the things started singing together and I have internet connection on both machines. via the wireless !!!!!!!!!

It seems to be flowing from the internet, through the modem connection in PC1, and then somehow out through the wireless link to PC2,

William can you tell me where the bridge operation in XP actually makes the linkage between the adaptors? is it in the software through buffers or in the hardware, cause this is now a bit surprising, especially as PC1's ethernet card says its disabled so something is doing the routing !!!

Best Regards

My names Curt, not William.

William is the name of the poet the quote at the end of my posts was written by....lol.

I've never played with briding in Windows. I'd wager a guess it's software though since you didn't make any physical changes to actual hardware to accomplish it.

If it's working, I'd stop right there and leave it alone.
