I've got a dd-wrt Linksys WRT3200ACS router working in 'AP' mode. My ISP supply a modem which runs a DHCP server. The modem is connected to the LAN port on my router and then the rest of the wired LAN is connected on the other ports. The router pumps out wifi. All other devices (wireless and wired) on my network work online perfectly.
From the router itself, in the shell, I can't seem to resolve DNSes. DNSMasq is disabled and Local DNS setting is 0.0.0.0. I can ping IP addresses on the internet directly, so it definitely has a working connection.
I've tried updating the local DNS setting in the dd-wrt frontend to both that of the ISPs modem (this is what all other devices get from DHCP) and also to 8.8.8.8 for Google's. Neither of these work.
root@Linksys-WRT-ACS3200:/tmp/mnt/sda1# ping google.com
ping: bad address 'google.com'
root@Linksys-WRT-ACS3200:/tmp/mnt/sda1# ping 216.58.198.110

Any ideas? Many thanks.
since your modem is doing dhcp, try disabling dhcp in the router. – Moab – 2019-02-19T19:43:51.767
Hi Moab. The DHCP Server is already set to 'Disabled' in dd-wrt. Thanks. – Jeff LeCoat – 2019-02-21T10:26:48.797
I'm voting to close this question as off-topic because the user went back to stock Linksys firmware leaving nothing left to be answered. – Tim_Stewart – 2019-02-25T21:26:04.780
Hi Tim. 'User' agrees. – Jeff LeCoat – 2019-02-27T09:58:38.780
