I use daisy-chained dlink Wi-Fi routers in order to pride Wi-Fi to all of our house. Using just one router on its own resulted in poor connectivity in a sunroom where the signal is low as a result of having to pass through a floor, an outside wall (party cemented), go outside and then come back in through a large glass/aluminum patio door. So, I placed the Secondary router in the Sunroom and ran a Ethernet cable back through the house to the Primary router. I used the well known approach for setting up the daisy chained system. I have done it in the past for other people.
Anyway, I also have two Chromecast devices. The one that is only about 4 ft from the Primary router works beautifully when I cast from devices that are also Wi-Fi connected to that router. The other Chromecast is in the Sunroom and it operated poorly (video stuttering and even sudden network disconnection) which is due to signal attenuation resulting from the above house factors plus the fact that the Chromecast device sits behind a large, wall-mounted flat screen TV and is wedged between the TV and the wall behind it. The TV also sits above a propane fireplace and I’m sure the metal stove piping also contributes to signal loss.
So, I thought I would connect my PC to the secondary router and then set up the Sunroom Chromecast to also connect to the Secondary router (which has a different SSID from that of the Primary router). Chromecast requires that both the casting device and the Chromecast be on the same network.
But I couldn’t do it. Even after a factory reset, CHROMECAST setup failed. Using the Secondary router/network was problematic.
So here’s the question. When Google says that both the PC and the Chromecast have to be on the same network, is it possible to create that second network via daisy-chained routers or is there some unpublished limitation in such an environment?
