No internet: synology rt2600 not getting ip and surfboard sb8200

[darwin321]

 My synology router doesn't get an IP from the surfboard. On the connection  field it appears as disconnected and it doesn't show an IP. I do get internet if I connect directly to the modem. Synology is connected to the modem through the wan port. What can I do to help set it up? I've been hours on this, so any help is very much appreciated!

There is a field in the primary Interface configuration that asks for ISP Settings which I don't know what to put, the parameters that it asks for are:

Hostname (option 12):

DHCP Client ID (option 61):

DHCP class id (option 60):

DHCP client option:

@sbernie2 I know you had a similar issue. Could you provide some help in this case?

You need to power cycle/reset the modem each and every time that you change the device that is being directly connected to it.

Thank you, @EG  I have tried that but when  setup at a wireless router (it also has the access point option) I still don't get an automatic setup from the modem to the router. The router doesn't have an IP. Would configuring it with a static IP be a good idea?

Do you have it in router mode (automatic configuration / DHCP) or is it in access point mode ?
