about how your laptop connects wirelessly to your desktop. Obviously your laptop has a wireless adapter, but you say your desktop is connected to the LAN by ethernet. Where/how does the LAN connect to the internet? What equipment specifically is at the "other end" of the wireless connection from the laptop and what is it attached to? What is the nature of the wireless connection to the desktop - infrastructure or adhoc?

When we have a clearer picture of your configuration we should be able to give some advice.

the desktop has a wireless pci card which connects it to the laptop.(ad hoc connection) the desktop is connected to a cable broadband through an ethernet cable. both computers say that they are connected to each other but i can't seem to access files on the desktop either. i have shared the folders that i wish to access but they don't show up on my network places on my laptop but they do on my desktop. someone told me i need to download a proxy server to access internet from laptop. what difference will this make?
i don't really want to purchase a wireless router. is there any other way around it?

Your best solution would be a wireless router. Simple, easy, quick, and takes care of the whole issue. You say you don't want to do that, but didn't give a reason why not.

A proxy server running on the desktop is a far distant second solution. You haven't yet told us what operating system is on the desktop, but if Windows 98 or later, you can use the built-in Internet Connection Sharing (ICS) function. It is Window's version of a proxy server, no need to get anything else. But be aware that it has its limitations and configuration quirks, and by the time you get done with it (or it gets done with you) you may wish you had just gotten the router.

As for the inability of the systems to reach each others' shared folders, are there any firewalls running? If so, thank them for doing their job of restricting access by intruders. Then reconfigure them to allow friendlies.

the main reason for me not wanting a router is the cost. I've already bought the network card because i was told it would be enough. I'm running xp on both machines if that is any help to you. And I have shared the internet connection on my desktop already. Are there any settings on my laptop that I should check that would prevent me using the network to access internet? Thanx for your help so far.

in theory...

it should work. If it is set up properly. The laptop should be set to acquire an IP address automatically, which it will acquire from the desktop over the adhoc wireless link, and the desktop will pass any packets it receives out to the internet over the wired connection to the cable modem.

But in real life, it is not always so simple. There may be addressing conflicts that have to be sorted out with the cable modem. There may be firewall issues that have to be sorted out. And so on.

You seem to be asking if you could do this. The answer is yes, you could. But, are you really telling us you are trying to do it and it doesn't seem to be working? If that's the case, you need to tell us some more specifics. What private IP address range, if any, is your cable modem using for your desktop connection? How is the ICS configured on the desktop, i.e., did you properly assign the roles of the ethernet and wireless adapters? What IP address does the wireless adapter on the laptop have?

i've been told that bluetooth dongles may be the best way to do it. do you know anything about them?

Bluetooth is just another way to send a signal between two points. You already have that. The problem is that something on this side of your cable modem has to perform the function of sorting out which of the several systems connected to it asked for this packet that just flew in from the internet. It would be a mess if half the pictures that showed up on a webpage on the desktop screen were in fact supposed to be part of the unfinished page showing on the laptop screen over there.

The proxy server handles this. ICS is a free proxy server courtesy of Microsoft. If you had a wireless router, this proxy server functionality would be imbedded in the firmware of the router. It may even be the case that your current cable modem has the routing functionality in it, in which case you simply need distribution functionality because the cable modem has only one ethernet jack on the back.

Bluetooth would add nothing to whether the laptop can reach the internet.
