GS108PEv3 hangs in bootloader mode
Hello, I tried to upgrade the firmware of my GS108PEv3. After ~ 30 minutes without activity and a completed progress bar I closed the browser window and power cycled the switch. I also tried pres...

Both a failed firmware image upload as well as pressing the button longer than about 3..5 seconds for a factory reset will bring the tiny controller into the recovery or loader mode.
Follow strictly https://community.netgear.com/t5/Smart-Plus-and-Smart-Pro-Managed/GS108Ev3-wont-complete-factory-reset/m-p/1581852/highlight/true#M9720 - of course using the GS108PEv3 firmware binary.
Be aware the ultra minimalistic IP stack on the loader mode does ot support much geeky features. In case the computer network interface is configured for JumboFrames, revert to 1500 or 1514.
I didn't do the paper clip dance with the factory reset button, but still think that what I did was in the limits of the description of the hardware manual.
In the end (and after contacting Netgear support with several failed tries) I found an old Windows VM; after some reconfiguration succeeded that I can access the switch webif and repeated the exact same steps with IE there. Worked as expected.
(See also https://community.netgear.com/t5/Smart-Plus-and-Smart-Pro-Managed/Can-t-update-GS108PEv3-firmware/m-p/1882522# for a similar user story.)
IMHO there is something broken in a subtle way when a http form works under Windows but not under Linux. I hope Netgear will do some research and fix that issue eventually. I wonder if I can use the non-loader webif without restriction from my Linux machine.
(As a side note: WIth V2.06.03 I often experienced that I have to power cycle the switch before being able to access the web interface under the address assigned by DHCP while the other devices in my network don't have similar problems.)
Thanks for your time

Uwe,
I think the problem is even on a lower level. If you are unable reaching the Smart Managed Plus switch IP addess the next time ... try adding a an ARP entry on your Linux (or MacOS!) system first.

Ahh, this sounds like a reasonable culprit. Will keep that in mind and try next time.
Thanks again for your time and thoughts
