Update to OpenWrt 21.02.3 has destroyed my WD N750

Why i should download the OpenWRT v19.07.10 from https://firmware-selector.openwrt.org/?version=19.07.10&target=ath79%2Fgeneric&id=wd_mynet-n750 instead from [OpenWrt Wiki] Western Digital My Net N750 ??

Thank you very very much for your feedback(s)...

My question was about a > 19.x version, prefered 22.x, with a special fix/patch for the Western Digital N750?

@hnyman @jow @tmomas, did version 19 have WPA3?

Or a way to install (and perhaps use the custom firmware selector to do so)?

@ all (Has a cause of the anamoly issue been discovered?)

@jmar83

I had no issues with v 19, it did not matter where I downloaded.

"did version 19 have WPA3"

-> No!

"I had no issues with v 19"

-> Same for me, my 2nd WD N750 still run with that version without any problems...

QUESTION IS STILL PENDENT: Is there a customized (custom compiled) v21.x or v22.x version for the WD N750 which has a fix / bypass / workaround for that issues...?

This is the best info I have:

I'm sorry I can't help with further details. I have been running version 22 on 4 devices. I have been posting updates in the threads about any issues. 1 2 have experienced 0 issues since flashing (it has the least config/file changes). Longest Uptime: 20+ days thus far (was on Solar/battery and I disconnected yesterday to maintenance the battery).

The 2nd I used a custom firmware (with the packages I need pre installed) I had no issues until one day LuCI and CLI stopped responding except to busybox. I rebooted and installed a firmware without LuCI. Uptime: 17 days so far.

Here's the post on all 4 again: Upgrade from Barrier Breaker 14.07 to latest 21.02 (WD My Net N750) - #36 by lleachii

I provided the link to the Firmware Selector - the downloads site was also provided.

(FYI I have a 5th device that's still running 18 or 19 - I left it untouched for future testing - in case this issue caused flash corruption.)

EDIT:

4 devices:

Devices 1 and 2 have:

base-files busybox ca-bundle dnsmasq dropbear firewall4 fstools kmod-ath9k kmod-gpio-button-hotplug kmod-nft-offload kmod-usb2 libc libgcc libustream-wolfssl logd mtd netifd nftables odhcp6c odhcpd-ipv6only opkg ppp ppp-mod-pppoe procd procd-seccomp procd-ujail swconfig uboot-envtools uci uclient-fetch urandom-seed urngd wpad-basic-wolfssl

This is the default list on the Firmware Selector for 22.02.3. These work for me without issues.

I've added the following without issues:

wireguard-tools snmpd tcpdump


As I noted 2 devices have 0 issues:

Also:

  • I expect that I will have issues running them if I make major config changes.
  • I'm still editing configs and uploading; but I have not attempted to make major changes since I removed LuCI
  • I will update when I have to change a device by CLI
  • I made a seperate post regarding creating archives on the command line because of this ongoing problem with the N750 - see: Create/restore backup archive from CLI
