Hello @Solla-topee 

It is slow as soon I connect to the WA850RE to check the parameters and configuration, some times I have to wait for minutes before be able to login or change between pages. It reboot when I try to login trough webpage or i'm trying to navigate between  different pages.

When it's not working no devices can connect to his network, the wifi network is unavailable, in this condition i'm not able to connect to the RE neither by wifi neither by ethernet so I cannot check his status. I can recover by removing from power and turn it on again.

I can see that sometimes it reboot due to the status leds turn all off, then goes back to on the power, Wireless and Ethernet led.

My router is a router of my internet provider, it is connected via Ethernet to the RE through a ZyXEL GS1100-16 switch.

Before the update the version was the TL-WA850RE(EU)_V7_200923, with this version there was no problems but I cannot go back.

here the label:

Thx and regards

Hi  @Solla-topee 

it reboot frequently when i try to connect to his configuration page.

Connected without the switch in between without improvements.

With factory defaults it works.... but is not what I need.

Already tried mor times to factory reset but sa soon I configure in AP mode I got troubles.

No power outage during firmware updates, I already tried to "reprogram" the FW with the same version but it does not solve.

My router is a "Swisscom, Internet-box 2"

Here a video of the led when I try to login on the config page:

https://youtu.be/Ur90Mg_RfYg it reboot often when I use the configuration page, less usual when I let it alone... but even une reboot is too often :-)

when I'm able to go to the firmware upgrade page i got the following error when I try to downgrade of the firmware:

It come just after I press the Continue button ...even If I try just after a factory reset with default configuration.

what about the exceptions I got in the log file?
