You do not feed it with a DSL signal but Ethernet. Try the following ...
Power up the 780, not connected to anything. Connect a PC to an Ethernet port, access the user interface and then:
1. Turn OFF DHCP server
2. Give the 780 a new IP address within the range of your current hub - maybe 192.168.1.78
3. Ensure wireless is turned ON, but without any encryption (temporarily)
4. Save settings
Power off the 780
Connect one of the Ethernet ports on the 780 to an Ethernet port on your existing 4 port switch and power it up.
Connect a PC to the 780 and using a browser go to the 780s IP address (192.168.1.78) - can you see the UI? Connect PC to another port on your 4 port switch and try again?
If you can see those then you should also be able to get wireless access.
If that works, then install it in the room you require it and you will have a switch with 2 spare ports and wireless.
Then set up Wireless Encryption.
I had an even older Speedtouch running like this for a couple of years without problems (except it was only 802.11b).
