Chromecast Google TV does not work well with wpa2/wpa3 security

Installing and Using OpenWrt
1

I have installed OpenWrt on a Linksys E8450 using the latest images from dangowrt's github page. Almost everything works wonderfully well.

I narrowed it down significantly:

  • My radios were configured to use wpa2/wpa3
  • A fresh setup of my google tv connects properly to it
  • anything that disconnects the wifi (router reboot, chromecast reboot) results in the device not being able to reconnect to the router
  • Switching to wpa/wpa2 had the device reconnecting instantly.

Anyone else has seen problems with wpa2/wpa3 configuration with Chromecast Google TV ?

Thanks!

Unfortunately Chromecast with Google TV doesn’t support WPA3.
Just use WPA2

Thanks for the answer. I wonder why it allowed me to set it up properly though.

No idea.
It really shouldn't have problem with mixed mode but who knows what Google did to their WiFi

I use one of these. As far as I'm concerned, wireless is for portable devices. Fixed devices get ethernet. What's the point of wasting RF bandwidth on something that stays put?

You can't expect everyone to spend extra 20 bucks.

Quite a few client devices don't work in WPA2/ WPA3 mixed mode, while they do work in either pure WPA2 or pure WPA3 mode. This is a client bug unfixable from the AP side, but that doesn't help proliferation of WPA3…

The problem is not that the wifi is hard to reach, which (could) justify the ethernet wiring.
It's a protocol issue that Google should address, so I'll submit a ticket.
In the meantime, WPA2 it is!
