Buffalo Technology, a subsidiary of Melco, is based in Austin Texas. Buffalo routers are fairly easy to configure. The configuration pages on any Buffalo router are basically the same, so once you have figured out one Buffalo router you have pretty much figured them all out.
Go ahead and select your router from the list below. If you can't find your router we recommend using our Buffalo WZR-D1800H guide. That router is should get you an open port on just about any Buffalo router.
