I sorted this out on the weekend. All I had read said I should turn off the device DHCP and wireless before connecting. I did a factory reset on the device and left everything turned on, and now the SG560 finds and used this direct dhcp connection.
Now I have a problem I had not anticipated.
This device is with ISP #2. My DSL is with ISP #1
None of my mail will go out due to server settings.
Is there some way I can tell all mail to go out through the ISP #1 server without changing all the client settings?
network sutup -> routes -> policy routes
you can route traffic out a specific link based on either source & destination address and/or port number.
