RB3011 can't connect to modem

RouterOS Beginner Basics
1

As far as I can tell, the router just isn't talking with the modem. On the Quick Set page I'm showing no IP address under the Internet section, and the "renew" and "release" buttons have no effect. Whenever I try to ping from the router outside the network I get a "No route to host" error, but I also get it while trying to ping the modem. Everything's running off the stock configuration, and if I connect a machine directly to the modem it functions flawlessly. The setup is > Netgear CM1000v2 > RB3011 > endpoints, including a CAP (but I'll get CAPsMAN sorted another day... having issues there too). Based on past posts, it seems to be a DHCP client issue I think? "ip dhcp-client print" returns:
Flags: X - disabled, I - invalid, D - dynamic

INTERFACE USE-PEER-DNS ADD-DEFAULT-ROUTE STATUS ADDRESS

0 I ;;; defconf
ether1 yes yes

“ip dhcp-client print” returns:
Flags: X - disabled, I - invalid, D - dynamic

That means that the dhcp-client of the rb3011-router is disabled
AFAIK in default config dhcp-client is enabled on ether1

So, as a quick solution, you could reset the router to default.configuration.
You have connected ether1 of the RB3011 to the modem haven’t you?

If you have only 1 or 2 CAPs you don’t need to bother with CAPSMAN.

No, that is a list of the possible flags.

The original post has

INTERFACE USE-PEER-DNS ADD-DEFAULT-ROUTE STATUS ADDRESS

0 I ;;; defconf
ether1 yes yes

which shows the DHCP client is invalid, impossible to guess as to why without seeing the actual configuration.
