Using a Netgear GS750E

[wrt-stefan]

Hello,

I would like to install OpenWrt on a network switch.
This will be the first time I use it on a switch, but i used OpenWrt already on many WiFi routers.

The GS750E has multiple problems with vlans with the original firmware, so i would like to use OpenWrt on it.
In case something breaks, I have a replacement device, which already has the same config.

Since the switch only has 8MB of flash memory, its not recommented to use it, but i already own it.
So, I would like to know how to install OpenWrt, but the wiki page is not available for this device.

I would like to use it with vlans (.1q), a firewall and luci WebUI for test purpose.
Later for productive i would like to use vlans, firewall, link aggregation and the prometheus node exporter to monitor it.
Has the device enought space to install it?

I found this.
Is this way the most recommented way to install it, or is or are already new informations available?
I saw in the past people used the snapshot version, because of a bug in 2023.
Is the version 25.12.1 stable for the device?

I saw that many using the snapshot version of OpenWrt for this device.
Is there a stable version, available now which works fine?

The swich should be my entry in the OpenWrt switch world, may later i will buy a better switch with more flash memory anyway.

Which switch would you surgest?

Thanks in advance.

Hello! As @frollic said, searching the forum with your model number would have been my first thought.

I think this topic may be of interest:

[Solved] Unbricking Netgear GS750E

So, finaly, I directly tried to reinstall OpenWRT following this process (method 2). After creating a TFTPD server on my laptop with tftpd64, I executed the following commands (full log below - I don't forgate to allow TFTP on my Windows firewall, the second time ) : GS750E# rtk network on GS750E# setenv serverip 192.168.1.234; GS750E# tftpboot 0x8f000000 openwrt-23.05.3-realtek-rtl839x-netgear_gs750e-initramfs-kernel.bin; Using eth#0 device TFTP from server 192.168.1.234; our IP addr…

Yes, I need to say that I read this topic already.
Thats where I copied the link from.

So, that means for me that this is still the recommended installation way.
And i guess for 25.12.1 it will be the same.

Usually I follow always the way which is in the device page. But this page was not available this time.
The *.bin files i found on the techdata page.

For any device added in the past few years the Git commit should have installation instructions. For this device the instructions are in commit https://git.openwrt.org/openwrt/openwrt/commit/?id=ea42a04161e3dee8fb1e67f48ccf8ce115617a9b.

You can certainly try a 25.12 image to see if it offers what you need. A lot of improvements have landed the past year.

I do see that the snapshot builds are at 7MB already, which is likely approaching the limit of being useful. A lot of devices have switched to using a self-decompressing image using the rt-loader recipe. You could have a look at switching to that to gain you around 1MB of useful space.

I have installed now OpenWrt on the device. And it works well so far.

I switched then later to 24.10.6, because i got an error, while building the firmware (with custom packages, using the firmware-selector).

The remaining spare is enough for me how it seams right now.

But I do stuggle with the Link-Aggregation.
For bonding i need multiple nics and i have only eth0 available, so it will not work.
I saw that swconfig can do this job, but it seams that the chip is not supported.

Is there an other supported way to available to configure Link Aggreagation on this device?
