I've got a ~10 year old non-smart tv, i've used a Google Chromecast for a couple of years without problems to stream from laptop or phone to the telly.
About 6 months ago the chromecast would disappear from the network every day or so and either have to be rebooted or alternatively I'd have to reboot the Wifi router, I tried doing a factory reset of the Chromecast and anything else I could think of but eventually gave up and got a new Chromecast.
Same problem.
I've changed the power lead, changed every setting I can find on the Wifi router.
I've not used it for a few weeks and tonight it took 10 minutes rebooting it and the Wifi router, then it cut out and stopped working after 20 minutes.
I can't update the firmware on the Talktalk router - although it may be technically feasible, it seems I would have to search out an update which isn't publically available and i'm not willing to risk screwing everything up.
I've got 20Mbps download speed, the Chromecast is probably 6-8m away from the router in the next room, but nothing has moved between it working and not working.
I really like the operation of the Chromecast (find something to watch on the phone, click the icon, on comes the tv) no need for a separate remote like the Amazon Firestick.
Anything else I can try before I end up looking for a new tv???
