At what address are you trying to connect to the WebUI? By default it should be using 192.168.0.1

Make sure you try to access it via HTTP, since the HTTPS may have been disabled after the FW upgrade.

Does your PC also get a IP from the DHCP server (if you have it enabled)?
If not, try setting up a static IP, in the same CIDR range and try again.
If does not work, try pinging 192.168.0.1, to see if responds at all.

Do you see any WiFi networks?

 

@ku4eto Thank you for the quick support. Yes I am trying to access the web Ui via 192.168.0.1. 

Now I have tried HTTP and it also doesn't bring the web Ui. 

I was using my modem as a bridge and using the ppoe username and password to get internet access before. 

Trying to ping 192.168.0.1 shows request timed out. (host unreachable) 

@Kevin_Z  thank you for the quick support. 

I just tried what @ku4eto suggested. But unfortunately that isn't working. 

 I just checked out the link you have sent me. Can you please point out which tutorial shall I follow for my specific device. 

Also my device is still under warranty. 

How complicated is the flashing procedure. 

If it is fairly simple, I can Try to do it myself. 

Again thank you for quick support.

Sorry for jumping in.

 

You can check ku4eto's suggestion first. If none helps resolve it, refer to this article to check if you can make it alive:

[Knowledge sharing]How to use firmware recovery if you bricked the TP-Link router?

@Kevin_Z Thank you, I just followed the tutorial that you have linked me. But upon completion, I am received with the above error screen. 

@terziyski Yes this is the exact zip file I have used. 
Just like the first time I ended up in this situation, I selected BIN file on web interface and clicked on upgrade. But Upon completion of 100%, I'm sent back to the initial page from where I selected the zip file.

So according to the tutorial https://www.tp-link.com/in/support/faq/1482/ 

After 100 % completion of Step 6, I'm set back to the screnshot in Step 4.

@terziyski thank you for your response. But I am not able to hard reset my device. 

I tried holding the reset button for more than 10 seconds and after powering on all the leds are lit up like the picture I have attached. 

There is no change in the status of led no matter how long I hold the reset button.

So after going back to step 4, selecting the zip file and clicking I'm back to step 4. 

So whom shall I contact now. 

Edit. A text saying "Firmware upgrade success." is shown for a split second after 100% completion of step 6 before returning back to step 4 screenshot. 

This is only shown in a split second. Had to screen record this to check out what the red text actually says.
