Stable firmware for TL-WR841N

[Pascal Laurent]

Good Morning,

What firmware could I use for the TL-WR841ND on a production environment? 

Does anyone currently using MESHDesk on their environment? 

Do you have any MESHDesk installation/Configuration documents you would like to share? 

Thanks,

--Pete

[T Gillett]

Which version of the WR841ND do you have?

Hi Pascal 

For WR841 Ver 9 you will need to use the SECN 3 BB based build as that h/w version is not supported in AA.

The SECN 3 current development firmware is here:

    http://download.villagetelco.org/firmware/secn/unstable/tp-link/SECN-3/SECN-3.0-Alpha9/

It is quite complete and stable and Dario in Argentina has been using it on WR841 in trials for a few weeks. 

I intend to push it to RC1 and GA-01 shortly so any feedback you can give us on it would be most welcome.

Please be aware that this is a sysupgrade image. 

You need to flash your device with a generic "factory" OpenWrt image first, then upgrade to SECN.

This ensures that the OpenWrt Failsafe mechanism is installed as a backup in case something goes wrong. (Dario can attest to its value :-) 

The OpenWrt stable BB images are here:

     https://downloads.openwrt.org/barrier_breaker/14.07/ar71xx/generic/

And you will need this one specifically:

     https://downloads.openwrt.org/barrier_breaker/14.07/ar71xx/generic/openwrt-ar71xx-generic-tl-wr841n-v9-squashfs-factory.bin

***NOTE****   When you upgrade from OpenWrt to SECN on the LuCI admin screen be ***CERTAIN*** to ***UNTICK*** the box that says "Keep settings".  Otherwise you will get SECN firmware trying to run with OpenWrt config files which is very confusing.

If this does happen, you can recover by using the SECN admin page to re-install the SECN firmware.

Lastly, would you be able to provide a brief outline of the network that you are setting up please?

Regards

Terry

Just flashed two WR841ND and wireless mesh works out of the box, with one connected to Internet and the other as a satellite (mesh) point.

Question: What is the static LAN IP on the SECN-3.0-Alpha firmware?

On the MP document, it specifies 10.130.1.20 or the Fallback IP address of 172.31.255.253

Are these addresses still valid on this build? Or are they different for TP-Link devices?

I can't ping or access the WEB interface by setting my IP, to any other, in these segments.

Thanks,

-Karl

[T Gillett]

Hi Karl

The default IP on the LAN ports is 10.130.1.20 on all builds.

If you have a static IP set up on your PC then you should be able to ping it via Ethernet LAN port.

You can also connect to the wifi if you set up a profile with password potato-potato  and static IP in the range.

Are you using Linux or Win PC?

Hi Terry,

This is WEIRD!

I was able to access 10.130.1.20, but by plugging into the WAN port!!!!!

The router I'm using is TL-WR841ND V9.3

There's no connectivity to 10.130.1.20 from any of the LAN ports. Only from the WAN port.

BTW, I'm running "openwrt-SECN-3_0-BB-Alpha10-wr841n-v9-squashfs-sysupgrade.bin"   and not the Alpha 9.

I'm on Linux (Mint) and I set my local IP to 10.130.1.99 and I played a while with the GUI and initially did the required telnet and changed password. All is fine now.

Thanks,

-Karl

Hi Karl

Not as weird as you might think.

The 841 for some strange reason has eth0 and eth1 reversed.

So the LAN is on eth1.

We allow for this in the firmware and so it should be correct.

But with 9 hardware revisions perhaps they have changed somewhere along the line.

I have cc'd Dario as he has been working with 841 devices recently and may be able to throw some light on it.

Dario - what hardware revision are your 841 devices please?

But does this mean that you are at least able to access the SECN config pages and the command line?

Regards
Terry

I have v8 and v9.2 versions of the TL-WR841N.

Once I install SECN in TL-WR841N, use the LAN interfaces of the device.

To know which answer, leave a ping 10.130.1.20 running and be connected the different interfaces and see who responds. I think the LAN 2 or LAN 3 ???

Dario

[Karl Wagner]

Yes, Terry,

I can acces the WEB interface and also  ssh the device, but only when I connect the ethernet cable from my PC to the  WAN port of the 841 :)

Hi Karl

It sounds like there is a problem with the eth ports changing between hw versions.

Would you be able to install OpenWrt uding their sysupgrade file and get a copy of the /etc/network file please?

That will tell us what is going on and I can update the firmware.

Is the wifi Access Point ok?

[Karl Wagner]

Sure!

I'll do that this afternoon.

BTW, the hardware version is 9.1 and not 9.3, which is what I posted earlier. I just checked the boxes. My mistake.

[T Gillett]

Thanks.

The major ver number (9) for TP devices is the hw rev.

The minor (dot) number is the sw rev when it left the factory.

Hi Karl

Apologies for the typo on the file name.

Interesting - as I suspected they have reverted to using eth0 for the LAN port.

Standby and I will run off a new firmware for you.

Regards

Terry
