I cannot ping ANY location period! No IP or domain name gives me a ping. I
time out every time. I have emailed tech support for my modem. I am using a
d-link dcm-200. It uses "56-bit DES (Data Encryption Standard) to encrypt
data transaction for both upstream and downstream transmission." Could this
cause such a problem? IT completely throws me for a loop that I can't ping
anything at all.
This may help with the mental picture. My home PC is the one with the new
modem and the connection problem. The remote desktop I want to connect to is
over the internet at another location. My PC worked fine with RD before the
cable modem and broadband service. Logic tells me that one of these is the
problem (Duh!).
