You can go USB or PCI but the best signal will generally be with a PCI card. Hopefully you're at SP3 on the device for security reasons. Proximity to the wireless router/AP and any obstructions could be an issue. The closer the better and with fewest walls, floors, and large metal objects would be best. Whatever device you choose, it will come with software as Windows will need drivers. I'll recommend that you find a way to load drivers only and not the other software that comes with these. Let Windows wireless zero handle the connection and make sure you're at least using WPA for security.
My old HP desktop is about 4-5 (at least) years old running XP. I am moving my wireless hub and want to move the old desktop and cabinet it is in out of its current location. My 9 year old is the primary user of it currently.
Bottom line is I don't want all those games on my laptop so I need to keep the desktop for him to use with internet. Is it as simple as buying a PCI wireless card or USB wireless and putting it in the vacant slot and hopefully XP will take over from there and it can then connect to my home wireless network from where ever I place it?
I see Tiger has some good prices on refurb cards I would think for this use those would be fine wouldn't you say?
Thanks for any input.
