I have encountered an interesting issue with Chromecast. Sometimes it works normally, sometimes it insists that it can’t find the device, which is on the same network, about 3 metres away. I posted about this previously because I couldn’t figure it out. Now I have finally stumbled on the answer by accident. It puzzled me for a long time. Maybe someone else has run into the same thing.

I use a Chrome browser on several Windows laptops. I usually keep the laptops turned on all the time. I have them set to go into sleep mode when the lid is closed. When I want to use one I just open the lid and it comes back on after a few moments. The wi-fi also reconnects after a brief delay.

What I have discovered is that Chromecast usually cannot find my cast device when the laptop is restarted this way. Everything else appears completely normal, but no cast device can be detected. What I have to do is close the Chrome browser and reopen it each time. Chromecast then works normally. If anyone else runs into this, that seems to be the answer.

Likely to be laptops than ChromeCast.


It's worth mentioning there is a known issue affecting certain Intel branded Atheros WLAN cards after resuming from sleep.


A driver update addressed this problem in W8.1/W10, but sadly no such update was made available for Win7.




Do you know the adapter type? Or laptop SKU?






Meanwhile you could try this?: 


Open Control Panel/Power Options/Wireless Adapter Settings & set Power Saving Mode to Maximum Performance.


Then in Device Manager look for the Wireless Adapter Properties tab & confirm Disable Device option is unticked.....

I personally never recommend anyone uses a Chrome on Windows with a Chromecast as they are flakey as hell. Tried on OSX with Chrome and it is slightly better but still not what I would call reliable.


Never had a problem streaming content from my Android or iOS devices to a Chromecast apart from when the phone goes to sleep and wakes up and has lost connection to the chromecast and the app needs to be restarted.


IMHO there is no better desktop solution generally available on the market to stream from a Windows PC to a TV. Airplay from Mac to an Apple TV is just so seamless and there isn't a free solution that works. I did have a look a while ago at AirParrot but just stuck with a long HDMI cable.
