I have about 7 systems networked on a second floor in a warehouse. They are all wired. There is one computer on the first floor that needs to be on the network also. Running another wired cable down there is not the best option. What route show I go? Should I get a wireless router and install a wireless card in the first floor computer? The second floor computers have a wired router and an 8 port switch. We will be getting cable internet shortly. I wanted to get the network out of the way before we purchased the internet access. What is the best method to go about this? I would like to see what some of you have done if you had a similar situation. Systems are mostly Windows XP.
