Installing OpenWrt on a Netgear WAC124

Installing and Using OpenWrt
1

Hi

I must be doing something silly, but I can't put openwrt 21.02.1 on a new Netgear WAC124.

Let me explain. About 8 - 9 months ago I bought two of these boxes from ebay as they were offered at a good price ... I junked the standard Netgear software and put openwrt on them, using the then current 21.02.1. It was a long time ago, but I don't remember any difficulties ... I'm pretty sure I used nmrpflash, and just flashed the squashfs-factory image. They have been working perfectly since then ...

I wanted to extend my WiFi into my garage, and found out that I could still buy another WAC124, so it arrived yesterday. I powered it on and logged into the Negear software just to check ... everything looked OK.

I found the directory on my desktop machine that still contained the openwrt squashfs-factory image that I had used before, along with the nmrpflash program, so re-read the reflashing instructions to acquaint myself with them, and proceeded to re-flash the box.

nmrpflash seemed to go through as I expected ...

sudo bin/nmrpflash -i eno1 -f openwrt-21.02.1-ramips-mt7621-netgear_wac124-squashfs-factory.img
Advertising NMRP server on eno1 ... -
Received configuration request from 9c:c9:eb:4f:e4:f4.
Sending configuration: 10.164.183.252/24.
Received upload request without filename.
Uploading openwrt-21.02.1-ramips-mt7621-netgear_wac124-squashfs-factory.img ... OK (6280479 b)
Waiting for remote to respond.
Received keep-alive request (2).
Remote finished. Closing connection.
Reboot your device now.

But the netgear box never responded to a ping on 192.168.1.1. I powered it off, and saw that the LED's were constantly rotating

ALL ON (1 sec)
POWER LED ON (1 sec)
POWER LED OFF, INTERNET LED ON (2 sec)
INTERNET LED OFF, POWER LED ON (5 sec)
ALL OFF (2 sec)

repeat ad-nauseam ... Don't know what any of that means tho' ...

I assumed that the flashing had gone wrong somehow, but I've repeated it 4 or 5 times now, with exactly the same results. However the really odd thing is that I then re-flashed the box with Netgear firmware (v1.0.4.2) ... the flashing process completed correctly and the box runs perfectly. So I don't think the flashing process is going wrong.

But if not that, what the hell am I doing wrong with the openwrt firmware ???

You try the other method: https://openwrt.org/toh/netgear/wac124#oem_easy_installation

Hi

nmrpflash is meant for flashing back the netgear firmware, so there is nothing odd in that it flashes it successfully :wink:

Restore netgear firmware (it seems you've already done it), and flash a factory image from within the Netgear UI. That is the conventionnal method to use.

4

So I used nmrpflash to put Netgear v1.0.4.2 on the box. This worked fine

Then I went through the logon process to set a root password

Then I reset the box to factory defaults

Then I logged back in and using the Netgear GUI tried to flash openwrt 21.0.2 squashfs-factory

The process looked like it worked. I waited about 10 mins after the reflashing process finished flashing the LED's, then powered off and on again.

No joy. The box does not respond to 192.168.1.1. The lights continue to flash in the pattern described above.

I even ran wireshark to see if the mac address of the Netgear box shows up when it attempts to boot, but I can't see any data matching this mac address at all, so as far as I can tell it's not actually going to respond to any network packets :frowning:

Stumped ....

Can you try the factory 22.03.2?

6

Thanks for your suggestion ... I have to leave this now until tomorrow.

I will try the newer version, but I know that 21.02.1 should work, it is already running fine on my other two units. I'm using the exact same file and nmrpflash that I used before (they have been sitting on the hard drive of my desktop machine). I don't see anything different about this unit compared to the others. It was new out of the box, and shrink-wrapped in plastic film, I don't think it is a re-furbed unit or anything.

Still stumped ...

I agree with you procedure.
https://www.downloads.netgear.com/files/GDC/WAC124/WAC124_V1.0.3.2.zip
Try this : use nmrp to install the oldest Netgear firmware, than flash OpenWrt from within UI. You may encounter an incompatibilty within the newer version of Netgear firmware. As you have already installed Openwrt on other such devices, you may not had the same Netgear firmware at the time. You can also try least older version.
And you can also try to install 22.03.2 as suggested by @d687r02j8g

This sounds like it could be due to the partition table. These devices contain a device-specific partition-table on-flash (which adjusts the partition sizes to compensate for bad blocks in the flash). However, OpenWrt uses a fixed partition table instead, which is only correct on devices without bad blocks. Devices with bad blocks on the flash may not work correctly.

Usually this just results in degraded wireless performance (as the calibration data is not at the expected offset). But if there is a bad block already before the ubi partition, this could also lead to the kernel not finding the root file system, which would cause a bootloop as described here.

If you are able to build an OpenWrt image on your own, could you try this patch applied on current OpenWrt master?

Aha ... that sounds interesting !

I've never built openwrt before but I will give it a go and let you know what happens.

As an aside, I ssh'ed into my other two netgear boxen and ran the dmesg command to see ... One reported a couple of bad blocks, but the bad blocks didn't actually seem to affect anything else. But the other one shows this

As far as I know this box is working fine, but this looks like it may be suffering from the bad block problem.

Lets get the build system working :slight_smile: !

So I have a build server set up. Currently compiling 'master'. If that works I'll try to load it to one of my good ap's, then try the bad ap as well.

After that I'll apply the recommended patch and repeat the tests.

Hi.
You don't need to install your own server, for simply building a test version. Use the online firmware selector, or the image builder. It's much more faster !

Hmm. OK, this is going to be one of those jobs.

I successfully built a squash-factory.img from openwrt-master. I just ran

make menuconfig     (I set  ramips/mt7621/netgear_wac124 then exit)
make download && make

I successfully loaded it to one of my good netgear boxes (one of the ones that was running 21.02.01), and the firmware loaded ok, and after the reboot, the box responds to a ping on 191.168.1.1.

However it does not seem to have the web frontend running. nmap shows that the only open ports on 192.168.1.1 are 22 and 53. I can ssh in to the box, but I don't know how to configure it without the web frontend.

I thought that if I used the netgear_wac124 profile make menuconfig would pick up the same packages that the official build does ? Am I wrong in that assumption ? And can I recover the build from the ssh console by adding whatever the required packages are ?

In anticipation that I can get this working, I also tried to apply the patch listed above. I downloaded the patch as a zip file, unpacked the zip file in the directory above where I was working and ran

wrt-dev{lidgaca} pwd
/home/lidgaca/wrt-builds/openwrt-with-patch
wrt-dev{lidgaca} git apply ../40397d37172220cac5953c1e2b4e0783-430669545883c1a4d971d23c9776dbdf46b18e87/sercomm-chj-bzw.patch 
error: corrupt patch at line 434

Line 434 is the last line of the patch file ... Is there another way to apply a git patch file ?

Help with any of these issues would be appreciated :slight_smile:

-- Chris

13

Did you add the Luci package ?
Hm ... you want to apply a patch, that's why you need the full build server, ok.

Hi

After a bit more poking around ... the patch file seems to be designed to be used via patch in the normal way ...

patch -p1 < patch-file.patch

I was confused, as the text header of the file said something like

diff --git ...

so I assumed it was to be applied via git apply. Using patch allowed the file to patch properly.

So I created a new patch-squash-factory.img, and it loads to the bad ap. Hooray ! So big kudos to janh :slight_smile: I can confirm that you were correct, and that your patch is good. If you want me to post the dmesg listing I can. Also if you need any other testing done please let me know.

However, after opening the beers, I'm still left with a system that only seems to have ssh on it ... I probably need to read some more of the dev guide (but if someone wants to tell me what to do here, I would be quite happy :slight_smile: ) I'm close to calling this closed now.

Thanks very much to all who have contributed.

That bad block is in an area of the flash that isn't used on OpenWrt (after the factory partition), so it shouldn't have any effect. There must be another reason for the squashfs read error.

It would be interesting to see the actual bad block locations on that device.

You need to select the luci package in menuconfig, as the default package selection on the master branch does not include the web interface.

Thanks for the heads up about luci ... I'm compiling a new version of the code now.

I'm including the full dmesg listing from the 'bad' unit that I successfully flashed with your patched firmware. I'm sorry for sending it all, but I wasn't 100% sure that I could edit out the useless stuff accurately.

What I saw was no indication of bad block scanning at all, and no bad blocks identified. Which I didn't understand :frowning: . Maybe it will make more sense to you ...

There was a change that disabled scanning for bad blocks. However, if you look at the partition offsets and sizes you can see that the kernel partition has an additional block on this device (block size is 0x20000 bytes / 128 KiB). So there is probably a bad block in there which the on-flash partition table compensates for, and as a result all following partitions are shifted by a block. (The same also applies to the "ML6" and "Traffic Meter" partitions.)
