86Chapter 4 Problem, Meet Solution Problems with Wi-Fi Communication If you have a problem using Wi-Fi communication: ÂMake sure you have properly configured the software according to the instructions that came with your base station. ÂMake sure the computer or network you are trying to connect to is running and has a wireless access point. ÂMake sure your Mac Pro is within antenna range of the other computer or the network access point.

ÂMake sure the side panel is closed (follow the instructions starting on page 46) and the PCI port access covers are in place (see “Adding PCI Express Cards” on page 68). Antenna reception is reduced when your Mac Pro is not closed properly. ÂCheck the Wi-Fi signal level. You may have up to four bars in the Wi-Fi status icon (Z) in the menu bar.
