Question about Galaxus 10 Gbit/s Fiber

I'm experiencing a complete failure of Wake-on-LAN functionality with the provided Zyxel AX7501-B1 router. My Fedora linux desktop (wired, static IP confirmed) cannot be woken by my Raspberry Pi (WiFi, static IP confirmed), maybe due to some isolation protocol that I cannot find in the router settings. I know that everything normally works fine because wake-on-lan worked completely fine with my previous router. Key Issues I Identified so far with this router: 1. Router's built-in WoL tool reports "Send Wake up packet success" but generates malformed UDP packets with invalid checksums 2. WiFi devices unable to send WoL packets to wired devices at all despite setting fixed IP address for the DHCP reservation 3. When the desktop sleeps, it disappears from the router's wired connections display, likely due to some ARP table issue with the router which I don't fully understand. Technical Evidence: tcpdump analysis shows the router generates corrupted WoL packets: [total length 33280 > length 130] (invalid) with bad cksum a4f9. This confirms the router's WoL implementation is fundamentally broken at the firmware level. Can Galaxus provide a firmware update to fix the WoL packet generation and WiFi isolation issues, or offer bridge mode to allow use of a secondary router for proper network functionality?
