MFC-665CW says printers offline need help!

i have an MFC-665FC printer on a wireless network with 5 other computers. 3 are XP and 2 are vista 32 bit. the 3 XP comps have had no trouble connecting and printing however the two vista comps cant print at all. it says Printer Offline under the hardware and sound tab in control panel. i tried switching the boot method to static instead of auto, reconfiguring the port the printer is on to RAW, and i have all the updated drivers and firmware. The online manual on the Brother website sucks when it comes to real troubleshooting and as a last resort i have come to this forum for some help or insight. If anyone at all has any idea whats wrong PLEASE HELP ME!!!!!

thanks in advance
