ping upstairs does indeed try to resolve 67.63.55.3. This IP address is nowhere in my network. "ping" does resolve it, but it takes about 23 ms. I have no idea why this should be. I have the exact same problem on 2 different networks in 2 different towns using different brands of routers. They both require the smb.conf fix as noted above to work. The only similarity between the 2 networks is that they both use the same ISP. Could this be somehow related to DNS by my ISP? The 67.63... belongs to a company on the other side of the USA from where I am.
