Hi all - my first post, so thanks in advance for any assistance you guys can provide!

I have the following home network;
1x laptop (Acer centrino with built-in wireless)
1x desktop (with PCI SMC wireless card) - this has an ISDN card for web connectivity.
1x Wireless SMC ethernet bridge/Access Point (AP)

...No ethernet cables are used to join any of the above.

Because the access point has a default IP of 192.168.2.25, I had a problem figuring out how to then enable ICS from the desktop - since this would give me an address of 192.168.0.1 - as per normal ICS setup.
My solution was to set the Access Point to have a static address of 192.168.0.100 and the laptop with a static address of 192.168.0.3
When I set up ICS on the desktop then, at least both laptop, access point and desktop would all be on the same IP range.

No probs so far - file sharing between the two PCs works perfectly and I can surf from the desktop computer.
...However, when I surf from the laptop, the pages come up blank!

Now for the strange part - and my reason for posting;
When I try to open a web page from the laptop, it cannot find the page - nor can I ping any external sites.
However, if I open the EXACT SAME web page from the desktop computer, the page opens on the desktop computer as per normal ....and if I then go back to the laptop and surf to the same page (with the desktop computer web page kept open), I get the web page on the laptop!!

huh?? Is this something to do with the fact that I've used static IPs in an ICS scenario? Has anyone else had this experience? I'm really stumped with this - going bald from scratching my head.

Any info would be highly appreciated!

Thanks again in anticipation!
Cheers,
kevin

Its been a while. With the ICS setup you have two network cards each with a different ip address?

Sounds to me like the dns server address is missing on the laptop. Set the dns server on the laptop to the same ip as the ics computer.

DNS though would not cause it to work after the other machine tried it.

If you go to any page on the desktop, thereafter you can go to any page on the laptop?

Hi - general reply to all; thank you for your feedback!

As far as DNS, I did actually try that as a last resort but made no difference.
Grinler: If you go to any page on the desktop, thereafter you can go to any page on the laptop?

...yes, this is exactly what's happening.
I'm going to the client on Tuesday to have a second look - I was thinking that perhaps an LMhost entry is causing this - any comments on that?

Nope I am pretty sure I know exactly what it is now from your last answer. ISDN is a dialup (regardless if its digital or not), so whats happening, when you go to a site via the laptop, ICS is not automatically starting the dialup of the isdn. Yet if you go to the web from the desktop its automatically starting the isdn, and therefore now the laptop can work.

You need to configure it, where i do not know, to dialup on any network activity so that the laptop can make the isdn dialup on its own. Just be careful as isdn here in NYC can be very expensive with usage charges if its on all day. Not sure how much it is out by you
