ER605 failed to upgrade to 1.2.1

  @linkerman Is your ER605 on the same subnet as the controller?

If the router and the controller are not on the same network, you may need to check the ports and make sure all required ports are opening.

Here is the related post.

  @Somnus It's on a different subnet from the controller, but all the correct ports on the controller are open.

Topology looks like:

ER605 <> Internet <> Nginx (for 443 only) <> Omada Controller v5

  @linkerman I had very similar issue upgrading eap devices, er605 worked without issues, but eap devices simply failed to upgrade. There was nothing in logs or visible. Some eap devices upgraded after third, fourth time clicking upgrade, but two of them simply refused, restarting network, controller and devices did not seem to help, however, even that device got upgraded after 6-7th time.

I tried a bunch of times, but nothing changes. These are the only logs I get from the controller.

  @linkerman I saw somewhere that upgrade failed issue may be also related to Download speed. I can't find that post now. Basically the logical is that if the controller took some much time to download the firmware, it will not able to upload the firmware to device properly.

I think you can try to download the firmware manually and upload it on the controller?

  @linkerman thanks for the log. In your log it clearly says following:

upgradeId- finished upgrade process in FIRMWARE_DOWNLOAD_FAILED

At least something, during my upgrades there was no indication to anything. If you had internet connection then of course it could be a bug, but probably you should ensure that you have internet during the upgrade, as example by pinging some server.

What I miss in your log is once again something that was told to tp-link multiple times, if firmware download failed, one wants to know the reason and here it is useful to show file hash of firmware to be flashed and downloaded file, but in logs there is none. It does not need to be no internet, it is sufficient if file can not be downloaded correctly and for some reason it is corrupted, this well could be on tp-links server, which might explain failures which I experienced, but like I said previously, there was nothing in logs indicating to anything.

@Somnus 

I don't think speed is the issue for me.

Home (ER605) speed test: https://www.speedtest.net/result/13325854881.png

Server (Controller) speed test: https://www.speedtest.net/result/13325851664.png

I tried uploading it manually via the controller and the result is the same. Same log messages and everything.

  @btx I have internet during the upgrade and don't have any ping drops.

Fully agree with you here. I wish there was a more detailed error explaining what the actual issue was.

  @linkerman thanks for the info, your internet can persist, but sometimes some files can be corrupted, this is especially often a case for commercial networks and student houses with cheap investment into monitoring and controlling everything, like when every downloaded file is checked by AV before it reaches your pc. A lot those things happen because something is wrong somewhere and in most cases have not much to do with users pc/device. However, you can check it by downloading manually firmware and checking its hash but it is a little bit tricky to  get hash of auto downloaded fw if it is deleted on error code (did not test but would assume).

You upgrade manually, but that is not solution to why download fails as well as is no solution to the info what happened but according to Logs download failed. Just make sure to download correct firmware for your device. You can downgrade same way back later if something is not working.

There could be also issue if you do use vpn or tor, maybe your address is blocked on tp-links side etc.., however, those are not public infos and you probably should contact tp-links support for more info and to ensure tp-links servers are not blocking your download.
