Hi everyone,
I’ve been trying to run cm data connect but this is what happens:
root@swi-mdm9x28-wp:~# cm data connect
Setting up profile 1
Connecting ... ok
Checking if device 'rmnet_data0' is up ... ok
Routing inet ... ok
mv: can't remove '/etc/resolv.conf': Device or resource busy
Routing inet6 ... ok
mv: can't remove '/etc/resolv.conf': Device or resource busy
Testing connection ... ok
After that I try to ping mangoh.io but not a single packet is received:
root@swi-mdm9x28-wp:~# ping mangoh.io
PING mangoh.io (35.184.189.106): 56 data bytes
^C
--- mangoh.io ping statistics ---
9 packets transmitted, 0 packets received, 100% packet loss
Do you know what’s going on?

How about ping 8.8.8.8 ?www.google.com ?
iptables -I INPUT -j ACCEPT

With these two addresses it’s basically the same:
root@swi-mdm9x28-wp:~# cm data connect
Checking if device 'rmnet_data0' is up ... ok
Routing inet ... ok
mv: can't remove '/etc/resolv.conf': Device or resource busy
Routing inet6 ... ok
mv: can't remove '/etc/resolv.conf': Device or resource busy
Testing connection ... ok
root@swi-mdm9x28-wp:~# ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8): 56 data bytes
^C
--- 8.8.8.8 ping statistics ---
16 packets transmitted, 0 packets received, 100% packet loss
root@swi-mdm9x28-wp:~# ping www.google.com
PING www.google.com (172.217.19.68): 56 data bytes

--- www.google.com ping statistics ---

How about shut down the firewall of the module?
iptables -I INPUT -j ACCEPT

I don’t know if I really want to disable the module’s firewall.
root@swi-mdm9x28-wp:~# iptables -I INPUT -j ACCEPT
And what about this? Might this be part of the problem as well?
mv: can't remove '/etc/resolv.conf': Device or resource busy

i don’t think that is a problem, please see my log:

I just tried to replicate your steps but it’s not working.

Regarding my last question, is this the correct way to disable the firewall:
root@swi-mdm9x28-wp:~# iptables -I INPUT -j ACCEPT
How would I enable it again?

you need to setup the iptables to enable the firewall again.

I also have a question about “cm data connect”.
root@swi-mdm9x28-wp:~# cm datagoogle.com are also OK in my opinion.
What is wrong with me?
