I connect to my RockPi4 via wifi hotspot and sometimes it has no network access despite being connected to the wifi network which is online. Other devices on the same hotspot can connect to the internet, how can I figure out whats the culprit?
nope. is it possible that networkd and connman are conflicting?
If the Wifi is connected, you should be able to at least ping your default gateway.
If you can’t, the wifi is not connected.
What’s the output of:

I am ssh’d into device via wifi
So it does have wifi. Good. What’s the output of ping -c 3 google.com?
yes but no network (I am connected to same hotspot with this laptop)
ping: google.com: Temporary failure in name resolution
And then ping -c 3 8.8.8.8?
invalid arguement p
Sorry, had a typo. It’s ping -c 3 8.8.8.8

Do you have both networkmanager and connman installed?
What edition did you install?
only connman, from official repo
I mean, what edition of Manjaro ARM did you install on your Rock Pi 4?
minimal
Why do you use connman then?
Minimal edition already has wifi capabilities, by way of iwd.
Remove connman, and create the connection with iwd from the device CLI.
Or remove iwd and disable systemd-networkd and systemd-resolved services.
is there a guide for iwd? i use connamn because its simple to setup
“Or remove iwd and disable systemd-networkd and systemd-resolved services.”
so these could be conflicting with connman?
Pretty sure they are. Since they also conflict with dhcpcd.
Guide to iwd:

systemctl list-unit-files --state=enabled:
…
dhcpcd.service enabled disabled
systemd-networkd-wait-online.service enabled disabled
systemd-networkd.service enabled enabled
systemd-networkd.socket enabled disabled
these are the relevant services, should I disable them all? i dont see iwd anywhere
I’m not a network expert. But try disabling dhcpcd and enable iwd.
Also check that systemctl status systemd-resolved returns it as enabled/running.
