Nanostation Loco 5AC loses settings upon reboot

Installing and Using OpenWrt
1

I've been struggling with my nanostation - turns out it seems the overlay fs is 100% full which is causing a host of problems, including losing settings upon each reboot. It is this way from a fresh firmware flash. Here are the details so hopefully someone can help figure out a fix:

root@OpenWrt:~# ubus call system board

        "hostname": "OpenWrt",
        "system": "Atheros AR9342 rev 3",

the memory loss is a bug, downgrade to 22.03, or use snapshots.

Thank you - I did not stumble upon that post when digging for info. I'll give that a shot.

5

yup, just like the info from @mk24 said.

Sorry, just saw the solution on the post you previously sent and tried to delete my previous post before anyone saw it LOL...

I'm having the same problem. And I can't find the 22.03.6 v. with the pacht " ath79: update WA/XC devices UBNT_VERSION to 8.7.4". When I try to upload the available 22.03.6 v. firmware it fails...

Does anyone know where I can find a compatible and working firmware for the NS 5AC Loco?
Is there any way I can force the installation of the existing 22.03.6 v or I have manually compile ?

Link to the refer pacht:
https://github.com/openwrt/openwrt/pull/14622/files with the message ailes because
:pray: :pray: :pray:

we can't work with "it doesn't work" ...

My solution to installing a stable version of OpenWrt (23.05.3) was to adapt and self compile the firmware on GitHub (some one alse in the forum indicates this solution). If you dont have GitHub you can compile in your computer.
I'm sure this can be optimized, but I'm noob, I hope It helps.

  1. Make a config file on your computer following this tutorial: OpenWrt Building System

  2. Create a new repository in Github and then copy the .config file that you have created from your computer to the root of the repository.

  3. In the repository folder ./github/workflows create a new yml file with the following commands:

    name: Build OpenWrt

on:
  push:
    branches:
      - main
  pull_request:
    branches:
      - main

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
    - name: Checkout code
      uses: actions/checkout@v2

    - name: Set up build dependencies
      run: |
        sudo apt-get update
        sudo apt-get install -y build-essential libncurses5-dev gawk git gettext libssl-dev xsltproc zlib1g-dev file wget
        sudo apt-get install -y build-essential clang flex bison g++ gawk gcc-multilib g++-multilib gettext git libncurses5-dev libssl-dev python3-setuptools rsync swig unzip zlib1g-dev file wget


    - name: Clone OpenWrt source code
      run: |
        git clone https://git.openwrt.org/openwrt/openwrt.git
        cd openwrt
        git checkout v23.05.3
        ./scripts/feeds update -a
        ./scripts/feeds install -a

    - name: Update UBNT_VERSION in common-ubnt.mk
      run: |
        cd openwrt
        sed -i 's/UBNT_VERSION := 8.5.3/UBNT_VERSION := 8.7.4/g' target/linux/ath79/image/common-ubnt.mk
      
    - name: Copy custom .config
      run: |
        rm -f openwrt/.config
        cp .config openwrt/.config
        
    - name: Build OpenWrt
      run: |
        cd openwrt
        make -j$(nproc) V=s

    - name: Upload firmware
      uses: actions/upload-artifact@v2
      with:
        name: openwrt-nanostation-ac-loco-firmware
        path: openwrt/bin/targets/

  4. Run the job on GitHub, and after finishing the compilation (takes around 1 hour and 30 minutes), downloading the zip file, extract the files, and install the Openwrt firmware as indicated on this website.

  5. Update and install luci and other packages that you need.
