Hi,
I had already switching problems on the ZyXEL XGS1250-12 with OpenWrt 23.05.X ... so I tried 24.10.0. Unfortunately I dont get any lan port running/connecting. Only serial works.
did you keep the config between 23.05 and 24.10? If so, try resetting your device to defaults -- from the serial terminal, issue the following command:
firstboot -y && reboot
Then see if you can access the device (it will be in the default config after that; so be sure to unplug it from your network, the only connection should be between your computer and the XGS1250-12).
If it still isn't working, use serial to grab the configs:
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:
Remember to redact passwords, MAC addresses and any public IP addresses you may have:
ubus call system board
cat /etc/config/network
cat /etc/config/dhcp
cat /etc/config/firewall
Thank you for the fast help!
Yes, I did the reset already.
ubus call system board

Ok... so in the default state, the address is 192.168.1.1.
Does your computer have an IP address in that subnet? If not, set your computer's Ethernet port to 192.168.1.5 (subnet mask 255.255.255.0) and then see if you can ping the switch (192.168.1.1). Make sure that there aren't any other network interfaces active on your computer (turn off WiFi if it's enabled now).
If that doesn't work, we'll try something else.
WiFi is off. I configured LAN manually.
ping shows unreachable network.
The switch doesnt even show light indication of than lan port.
This is most likely related to this bug https://github.com/openwrt/openwrt/issues/17010
Yeah, looks like it.
How can I install another OpenWrt version (old one or snapshot) if I have only serial access?
You can drop into uboot shell and connectivity should be working there if you run rtk network on. Then you can boot and install via tftp, see https://openwrt.org/toh/zyxel/xgs1250-12#booting_openwrt_from_ram
How can I go into uboot shell? Is it the Serial + STRG+C + Eneter (looks like I am in OpenWrt with ssh)?
root@OpenWrt:~# rtk network on
-ash: rtk: not found
Btw: fw_printenv shows:
bootcmd=rtk network on; boota
Change boota to bootu
Thank you, @antanas !
I was able to do the tftpboot:
tftpboot 0x84f00000 192.168.1.10:openwrt-23.05.5-realtek-rtl930x-zyxel_xgs1250-12-initramfs-kernel.bin
Using rtl9300#0 device
TFTP from server 192.168.1.10; our IP address is 192.168.1.1
Filename 'openwrt-23.05.5-realtek-rtl930x-zyxel_xgs1250-12-initramfs-kernel.bin'.

Whats the next step? reboot command does not exist...
Check help command it will show you whats available. I don't remember exactly but it's probably bootm that would boot the loaded image
Thank you so much!
Yes, it was bootm. Now I reverted back to an older OpenWrt version
