Sounds to me like you have a problem with the wireless router.
The IP address issue maybe causing a conflicts with another device with the same IP address.
Try changing your IP address on both Macs and Windows PC to see if that make any difference with the router.
Best of luck

Do you know how to change the ip address on a Mac?
