I notice that many posters are able to set up their PCs to connect to
internet wirelessly, but have problems sharing files & printers. I had this
problem too, and after some research, was able to get my home network
working properly (2 desktops & 1 notebook). Here are some pointers (for Win
XP Home or Pro only):-
1. Go to Control Panel / System. Hit the 'Computer Name' tab. The
'workgroup' name must be EXACTLY the same on all the PCs to be linked. If
it isn't, hit 'Change', type the workgroup name correctly & reboot the
computer.
2. I assume you're using firewalls (I was using Norton Internet Security in
one desktop, McAfee Internet Security in the other, and Windows Firewall on
the desktop!). Go to firewall settings / trusted IPs and key in the range
of trusted IPs (you can safely key in the entire range of 192.168.0.0 up to
192.168.0.255).
3. Enable sharing of the printers/folders (right click the printer icon or
folder and enable sharing under the 'sharing' tab).
4. Add a network printer in all the PC's not directly hooked up to the
printer. It doesn't matter whether the PC is hooked through the serial or
USB port - it can be shared either way.
5. If you still have problems, you can troubleshoot as follows:-
a. go to Command prompt, type 'ipconfig' and hit enter in each PC to get the
IP address of your PC & default gateway (which is the Wireless Access Point,
usually the same as the wireless router).
b. 'ping' all the other PC's in the network (including the router) - you
should get 4 packets sent & 4 received. If not, there's a problem with that
particular link. (Syntax for 'pinging' is PING 192.168.0.102 or whatever the
IP address is).
Mine is a D-Link 624+ wireless router, D-Link PCI cards on the desktop &
D-Link PCMCIA card on the notebook. Regardless of your system, make sure
you enable some form of encryption!
