I have been trying to set up 2 computers using just purchased usb wireless adaptors betwen 2 computers (one laptop) both running identical Windows XP SP2. The wireless connections are 100% fine signal strenth excellent etc etc. but I cannot see files on either computer, or connect to the internet from the laptop through the host computer (my PC tower). This is connected to a local microwave ADSL at about 1 Meg.

I have set up the TCP/IP and Subnet MASKS. I understand that ALL connections must have different IP address, but ALL Subnets should be the same. What about default gateways??

I have tried a mass of different combinations but to no avail. I am somewhat new to Networking - but I am at a LOSS here as to what to try next.Correct me if I'm wrong...

You have a total of three computers, two of them XP SP2, correct? What about the host computer...what operating system is on it? Is Internet Connection Sharing enabled on the host? Also...are any of your firewalls blocking the connections?

Here are some useful links:

Setting Up a Home NetworkI have just 2 computers. My host PC is successfully connected to the internet via a microwave connection giving me 1Mb. Only recently I upgraded my old Dell notebook to RUN XP. I bought 2 Wireless USB adaptors 802.11g - (one PCMCIA for the Dell). These are successfully connected to each other, but I cannot see either computer on the other one - nor can I connect to the internet from the Dell.

At the time of writing this I am not sure if the PC is configured for ISC. Can you tell me how to do this - though I will try after posting this reply.

Thanks again . . I have disabled all firewalls - does not make any difference . . Hopefully, this article will aid you...
