I recently switched internet providers from Digis to Comcast. I am using the Motorola SB6121 Modem and a Zonet ZSR4134WE Wireless Router. No problem getting on the internet, but I can no longer get Remote Desktop to connect. If I remove the Zonet from the set up and go straight into the modem it works. If I set everything back up using Digis as the provider it works. I am not changing any settings on the Zonet when switching between providers so I am at a total loss as to what the issue is. Comcast says they aren't blocking anything...and since everything works except what they consider "software" they have no advice. I can't contact Zonet, because they don't exist anymore. I am sure there is some simple setting to change, but there is no way for me to find it. Any ideas- any at all?
