Netgear GS308T v1 Installation Failure? (RTL383x)


The commit instructions say the OpenWrt ramdisk image can be flashed directly from the Netgear user interface, so that's the approach that I took.

I got the following snapshot image:

  • openwrt-realtek-rtl838x-netgear_gs308t-v1-initramfs-kernel.bin
  • 78dae1ecf17e73c0cc02dfef985079656a982bd0ab2eaf23f400da2968bef88e

And uploaded it to the switch (that had Netgear firmware to the first image slot via HTTP then rebooted the switch.

However after reboot I am not able to access the switch via SSH to proceed with the installation (scp sysupgrade, ..). The orange power light shines when it's powered on. I can not ping it. If I plug it into a different managed switch the port is shown as having link status of down.

Apparently the switch should be accessible on on all ports without VLAN according to Support for RTL838x based managed switches - #956 by svanheule

Regardless I used the following to try VLAN 100 on port 1 without success:

# ip link add link enp2s0 name enp2s0.100 type vlan id 100
# ip link set dev enp2s0.100 up
# ip addr add dev enp2s0.100

As far as I can tell I did what I was supposed to and did not make a mistake.

Anyone have some more recent experience with GS308T v1 or RTL838x switch to share some advice?

Thanks in advance!


Looking at the other threads on the forum:

  • no I did not accidentally flash openwrt-realtek-rtl838x-netgear_gs308t-v1-squashfs-sysupgrade.bin
  • i have tried port 1 with vlan 100 to no avail

At this point you will likely need serial access to the switch to determine where/what is failing. See the commit comments at;a=commit;h=c829bc1f2c3c47e230905864f2f5f8c759f88ce6 for how to access the serial port.
