Losing my mind, No DNS after APN change

Factory stock, jumps on the firstnet-broadband, get an IP and DNS works like a champ.
Set the unit to our custom APN
#uci set network.wwan.apn=34044.fn
#uci commit network
#service network restart
Jumps on my APN, gets the right IP. But here's the kicker, DNS resolution is gone.

#nslookup www.google.com
;; connection timed out; no servers could be reached

If I specify the server to use all is good.

# nslookup www.google.com

Name:      www.google.com
Address 1:
Address 2: 2607:f8b0:4008:809::2004

What am I doing wrong? dnsmasq? Noob if you can't tell :slight_smile:

Going to get some tcpdumps to see if anything leaves wwan0.

Thanks in advance guys!

Okay wasn't expecting that, nothing egresses wwan0 during an nslookup. Mmmm....
Got to be this dnsmasq that I've never even heard of before, no?

Am I on the right track? I need some URL's with some good examples how to configure the dam thing. I'm digging in the mean time.

Think I found it,
The bone stock unit has

config dnsmasq
 option resolvfile '/tmp/resolv.conf.d/resolv.conf.auto'

That file exists and contains


The unit I changed the APN the resolv.conf.auto file doesn't exist. Man I've got a bunch to learn. But I'm getting close.
