I recently purchased a laptop (vista home) for a young friend and a Netgear DG834G modem router for her to set up a home network with her mother. Mum runs a desktop with windows XP SP2. Connecting the modem router to the desktop (by cable) was no problem, as you might imagine, and I eventually managed to connect (wireless) the laptop to the router. They now wish to share the printer connected to mum's desktop, and files. Every time I run the network wizard it fails at the final hurdle and gives me the message like "unable to terminate connection". Similarly, when i separately to share mum's printer and click on share this computer it comes back with "printer settings could not be saved, operation could not be completed" On another and perhaps related problem, I am unable to adjust the settings of windows firewall. I can not access it at all. grateful for any advice.
