Portable hotspot works correctly.
Leaving the router off for 10 minutes didn’t fix the issue.
Turning the router to 2g only also didn’t fix the issue.
It still looks like the DHCP request isn’t working. On my main router’s side, I see Beryl with a wrong old IP (left over from the mobile hotspot): 192.168.9.x.
In the logs, I still see the DHCP requests being sent:

Manually renewing DHCP lease also doesn’t work:

udhcpc: started, v1.30.1

^C
However, I seem to be able to manually fix things!
root@GL-MT1300:~# ifconfig apclix0 inet 192.168.1.177
root@GL-MT1300:~# route add default gw 192.168.1.1
root@GL-MT1300:~# cat /etc/resolv.conf | sed -e ‘s/127.0.0.1/192.168.1.1/’ > /tmp/resolv.conf
root@GL-MT1300:~# cp /tmp/resolv.conf /etc/resolv.conf
root@GL-MT1300:~# rm /tmp/resolv.conf
At this point, the router has internet connectivity:

And the web interface shows a connection:
But unfortunately, it’s not responding to DNS queries. And the internet connection seems to be intermittent:

And a logread shows that the interface seems to be going up and down:

So my current state:
- DHCP requests don’t seem to work
- I can manually configure things to work, except for the Beryl’s DNS server
- IP connectivity seems flakey; sometimes it works and sometimes it doesn’t. Probably due to interface going up and down.
- Beryl is about 10 feet from main router with no obstacles in between; signal quality should be perfect.
Where/how can I capture additional logs? What do I try next?
