I got two problems while installing the wireless Printer for my desktop: 1) Your wireless router requires a WPA security passphrase. The passphrase configured on your printer does not match exactly. Reconfigure your wireless network WPA security passphrase for your printer. Q) What is to be done to solve the above error?and where do I configure this for the printer? 2) The printer attempted to join the network but is not receiving any data. This may be caused by MAC address filtering. If MAC address filtering is enabled and you would like to keep it enabled, add the MAC address of your printer to the list of permitted devices for your wireless access point or router before continuing. Print the Wireless Network Test report from your printer to find the MAC address of your printer. Q) Now , I got the mac address , how do I proceed?
