Hello,

I had a DLink modem/router and I replaced it with the TD-8970.

Before I changed it, I could connect through Remote Desktop to my other PCs on the local network.
After I replaced it with the TD-8970, I couldn't connect using Remote Desktop to any PC on my local network.
All PCs get IP address from DHCP, they are on the same subnet as before.
No changes on PC settings has been made, RDP Port 3389 is open on PCs, remote desktop services running, and there was no change in network topology as well.
I just replaced my DLink modem/router with the TD-8970.

I tried opening ports on the TD-8970 but I still couldn't connect.

So, what am I missing here? I spend too many hours trying to make RDP work on my home network and I still can't fix this. I have never had any similar problems with other modem/routers.

Can you please help me?
