saladin · 2025-04-05T10:23:37.598Z

Hallo,

I send the link of the zyxel for this model ZyXEL EX7501-B0 specifically, it is the 10 Gbps wan/lan model.

do you know if it can be supported by OpenWrt? I do not find it anywhere.

Thank you!

Depends on the hw inside.
Open it up, post photos of the PCB, and the boot log.

B0 are Broadcom…. Don’t waste any time

I am thinking to buy one, but I do not want to end up with unsupported platform for openwrt

I read that B0 is Broadcom
But there is no conclusive evidence supporting such claim

No pictures, no reference to device details

Zyxel AX7501 with XGSPON SFP+ 10GB Fiber router support For Developers

Hi I just got the official Zyxel source code dump of the latest firmware version PX7501-B0(V5.17(ABPC.3)D0 to study. And what a surprise for me to find the header of openwrt everywhere spread in the source code Copyright (C) 2007 OpenWrt.org found reference to Barrier Breaker, aka 14.07, circa 2018 CONFIG_TARGET_NAND_FLASH_TOTAL_SIZE=256 CONFIG_TARGET_BOARD="brcm963xx" CONFIG_TARGET_ARCH_PACKAGES="brcm963xx" CONFIG_DEFAULT_TARGET_OPTIMIZATION="-Os -pipe -march=armv5te -mtune=xscale -fno-call…

They are not the same:

AX7501-B0 ≠ EX7501-B0

They will be, until proven they're not.

saladin · 2025-04-06T07:27:07.425Z

They are not, untill proven otherwise

Whatever floats your boat.

Zyxel in its products inserts the vendor directly in the name, -B stands for Broadcom, -T for TrendChip (now Mediatek), -R for realtek, -D for Lantiq (I don't know why D).

So it definitely uses a broadcom SoC

I will try to get a EX7501 to settle down such dispute
Will keep u updated

It might be right that it's broadcom based, lot of cheap wifi7 devices started to showing on market with broadcom based hw. The hardware is better but opensource support close to none existing.
