Installing and Configuring ZyXEL WSM20

Installing and Using OpenWrt
70

Hi,

I was quite puzzled by that sencence (that I saw in post from @ghen as well), and I can confirm, after a test with another unit.
These are my updated notes for the process (since I had some trouble the first time with https://openwrt.org/toh/zyxel/wsm20:

Prerequisites [Win10]:
Download the files “initramfs-kernel.bin” and “sysupgrade.bin”
Install the tool WinSCP
(Read the instructions in https://openwrt.org/toh/zyxel/wsm20)

Steps:

  1. Connect PC to LAN1 of the WMS20 and type in the browser: http://192.168.212.1/
  2. At the first error move ethernet cable from LAN1 to WAN and press OK. Wait (10 minutes?) while it stays in “Step 2 of 3. Polling WAN Port” and move the ethernet cable from WAN to LAN1; in parallel, open another tab in the browser with http://192.168.212.1/gui/#/main/debug/firmwareupgrade
    and upload the initramfs-kernel.bin file.
  3. Wait until it is installed. Do not look at the pages in the browser
  4. Open WinSCP and connect to 192.168.1.1 (other default settings) and confirm
  5. Upload (F5) the sysupgrade file to /tmp
  6. Open a terminal in WinSCP and run the command: sysupgrade openwrt-23.05.0-ramips-mt7621-zyxel_wsm20-squashfs-sysupgrade.bin
  7. Wait until the led is still white
  8. Connect to 192.168.1.1. Luci is there! You can close WinSCP

I hope it helps someone that is starting with OpenWRT and the WyXEL WSM20
