Hello, with the 1.4.5 version, is there any error message when you try to switch to AP mode? You can no longer log into its web UI by tplinkwifi.net?

If you connect to its wireless network, can you access the internet? How about the IP address you will get from it?

Hello,

There is no error when switching to AP mode. After the switch into AP mode on 1.4.5 I can no longer access the UI neither via tplinkwifi.net nor via 192.168.0.1.

I have also tried to connect via WLAN and also via LAN but no success.

The WLAN network is created but the UI is not accessible and there is also no internet

The router keeps restarting every aprox. 30 seconds, seems like it is failing to boot in AP mode or something like this.

In order to gain access to it again I have to force reset it and load the firmware manually again.

Also loading the 1.4.5 manually does not work and causes the same issues when switching into AP mode.

Any ideas what can cause this?

Thank you!

@oligliga12 I have exactly the same issue. But i cant reset the router, and i have not access to it.

@Lupindue Hi,

The new firmware version for the Archer C80 has been already release and can be found under:

https://static.tp-link.com/2020/202007/20200729/Archer%20C80(EU)_V1_200628.zip

Or simply search "Archer C80 firmware download" and it should show you the release mentioned above. (200628)

Just make sure to have the right one for your region (EU or US). The one mentioned by me is the one for EU.

I was in contact with TP-Link UK in order to get this thing fixed and they already released the new firmware with the correction for it.

You can install the new firmware by force resetting you router (press and hold reset button on the back for approx. 10-12 seconds).

After the complete restart you will be prompted with the screen mentioned by me in the original post which will allow you to manually load the new firmware into your router.

Just make sure that your router is connected via LAN (cable) to your laptop/PC during the upgrade.

@Solla-topee Can you maybe give @Lupindue other steps in order to get this corrected? In my opinion this is the only solution that should totally fix the issue.

Hope this helps,

Oli

@oligliga12 Finally i can solve the problem. I cant reach the web page, because i have the lan cable connected via wlan port, once i connected via lan, and set the ip of the pc manually in the range of 192.168.0.1, i could upload the new firmware, and i have the router working well yet.  Thanks.
