Given the slim details we can't start a discussion. Try adding to your post by replying to your top post with details about the router (make, model, firmware revision) and let's see if that's enough.
I have a Windows 7 lap top and an Iomega eGo external hard drive. When I plug the hard drive into my computer via a USB, it works fine, but when i plug the hard drive in to the wireless router, I can not access it, and I would like access the hard drive wirelessly, can anyone help me get this done??
