Chromecast 3rd Gen wont pick up wifi

Since last week, I have not been able to get either of my two chromecast to connect to my wifi which is provided by my Telstra Smart Modem Gen 2. I am on NBN. I have had no issues until now. I have reset both chromecast, tried on two different tvs. I have tried to connect through google home app using different phones. I have installed the google home app several times. I've even gone into the modem settings via browser and disabled band steering.

Hey mate, 

I'm going to guess your Chromecast has recently updated firmware 275994. This firmware has broken connectivity to 5GHz upper range channels (149-165).

There are two sub-optimal workarounds available until Google fix this defect:

  • Change the settings in your router to use a lower channel (36-48; not Auto) for the 5GHz network.
  • Connect your Chromecast to the 2.4GHz network.
