If you did not power the router off and back on, try that. I would try a reset to factory before I tried to install the firmware again.

Thank you for the quick reply.  I did power off the router and then back on.  As far as resetting to factory and updating again, I'm a bit reluctant to do that since the router appears stable and working well - with the exception of the above mentioned "problem".

I understand. Every month or so make it a habit to check to see if there is any new firmware for your router (and your other devices). Also it is a good time to back up things both before and after any firmware upgrades.

Have you looked at the Support Page for Firmware? Do you actually have the one listed there?

 

I did, https://www.tp-link.com/us/support/download/archer-c5400/#Firmware and something is clearly wrong?

 

First you present version listed, " Firmware Version: 1.2.5 Build 20190411 rel.52981(5553) ", which appears to be built on 4/11/2019. However, that doesn't match ANYTHING on the above link? However, https://static.tp-link.com/2019/201911/20191107/Archer%20C5400(US)_V2_190411.zip is listed on the page as released on 11/17/2019, but the file has the last part of the name as '190411' which would be 4/11/2019?

 

So, either there is a mess up on the d/l page OR it might have been updated for some reason and the date not changed?

 

If you look at the above d/l page link, there are 3 prior releases, and the file date does match release date.

 

Something odd it seems to me?

 

I took the file down and opened the ZIP. The ZIP itself has a 10/27/2019 date on it for the folder, but inside is the 4/11/2019 for the firmware.

 

So the question now is how long have you had the router or did you not notice the update before?

 

One thing to try, contacting support and ask about this, OR, if you are 'brave', get the file and try installing it. If it is NEW it will install, and possibly will if it is the same as you have now.

 

Confusing though for sure, especially if this just popped up and you've had the router for over 2 years? If you bought it past 4/11/2019 it should have probably had the same f/w you are using now and never been updated?

I suspect that this is not a US version router, hence the firmware version differences. This forum is the US based forum but we try to help all. There is an English forum which may be able to help you better as they may have seen this issue if it evolves a non US router. See https://community.tp-link.com/eg/home/forum/32 (difference is "eg" vs "us" in link).

It is a US router.  Bought about in March 2018.  I have used the US based firmwares since the beginning. Hopefully someone from TP-Link will respond soon.  Thanks . .

I had alo noticed the discrepancy in the file dates. I agree that it does appear a bit strange.  Hopefully a TP-Link representative will answer . .  Thank you.

I assume the label on the router has 'US'. I wonder if somehow you loaded a different country's firmware? Do you still have the link where you got the firmware?

@ArcherC8 

 

Yup - it says "US".  I downloaded the firmware directly from the TP-Link website: https://www.tp-link.com/us/support/download/archer-c5400/#Firmware

I think your next step is to call support. This is strange.
