Can someone please explain to me why my router keeps on restarting on various times repeatedly?
This doesn't really show anything actionable.
Let's start with this:
- Have you installed any non-default packages? If so, what?
- Let's see the config:
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button (red circle; this works best in the 'Markdown' composer view in the blue oval):
Remember to redact passwords, VPN keys, MAC addresses and any public IP addresses you may have:
ubus call system board
cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall
(also, in the future, please don't post screenshots of log output.... instead, provide the text directly into the forum, formatted as described above.)

start by upgrading ?
you're 3 release behind ...
I am afraid I lose configuration or something goes wrong.
will changing the lan protocol to dhcp client assign IPs to all devices?
no, it won't.
You can sysupgrade one major version at a time, you can check functionality at each step, or go step by step and check only the last one.
First make v21 config backup - if something goes south you will need to type it all back in v 24.10.4
. https://firmware-selector.openwrt.org/?version=22.03.7&target=lantiq%2Fxrx200&id=bt_homehub-v5a
etc etc.
This won't help with the current situation on the BT Hub 5. This is because the currently installed version (21.02) uses swconfig on that target. At some point between that version and now (24.10) the target was transitioned to DSA. This means that there is a mandatory reset-to-defaults as part of the process during the upgrade (not sure off hand if the DSA transition occurred with 22.03, 23.05, or 24.10, but one of those will require the reset).
The good news is that the config is not far from defaults, so it shouldn't be hard to recreate the general configuration -- probably about 10 mins of work, max.
With that said, the best option is to make a backup of the current config. The backup is useful as a human readable reference for the wifi and pppoe settings should they need to be replicated. Do not attempt to restore the backup to 24.10 as this will soft-brick the device.
After the backup is done, upgrade to 24.10 with the "keep settings" option unchecked (or -n on the command line) to ensure that it resets to defaults. It is fine to try to go directly to 24.10 (as long as you do not keep settings), but it is possible is that incremental steps will be required since the version jump is large.
I can confirm that my HomeHub 5a can reboot on random after I've play around ethernet wiring. Ethernet was flapping and had random reboots. This never happened when I was on FB 7362SL. Please check the wiring.
