Oh I see, sorry about that.

 

We have confirmed again and it seems that the current version on your WR841N is for the US version, which can be found on the US website:

https://www.tp-link.com/us/support/download/tl-wr841n/v11/#Firmware

 

As you know, it's not suggested upgrade the device firmware across regions and it will be against the warranty, and a wrong firmware upgrade may damage your router or cause the router to not function properly.

 

Hope you could understand. Good day.

Hello,

 

Before this firmware update on the router, you need to unzip the downloaded file first, you may install a WinRAR or WinZIP on your Windows computer.

 

Then refer to the below instructions to upgrade the firmware:

Good day.

@Kevin_Z  thanks for your advice, however this is not the problem. 

I have of course unzipped the zipfile and uploaded the .bin file via to the web interface when I tried to upgrade the firmware. 

I tried this for both versions, and both failed. 

 

The .bin file names are: 

 

wr841nv11_wr841ndv11_en_3_16_9_up_boot(150616)

wr841n(EU)_v11_160325.bin

 

I even tried to rename the file to a smaller file name, as some systems dont like long filenames. I used the short filename (8.3 )naming convention .   

 

I have upgraded many routers over the years, so I generally know how to go about it. Posting on this forum because there are no existing fixes that I can find on this forum or google search. 

 

Any further advice welcome
