I see that Chromecast only show up on my smartphone when I connect the Chromecast with wifi, but when I switch to Ethernet cable, the cast icon disappear.
Many people have the same question:
- Chromecast Ultra not working over Ethernet ever since switching to
AT&T- Why does my Chromecast Ultra disappear when I connect it
with an ethernet cable?(I make this question because I want to give a better answer)
Answer
If your Chromecast uses Ethernet cable, then the casting device (PC, Tablet) must also use Ethernet cable.
For example, this will work (tested and work on a Windows PC, successfully cast Youtube, Dailymotion,…):
-
step 1: Connect your ChromeCast with the Ethernet cable.
-
step 2: Connect your PC with the Ethernet cable.
-
step 3: On your PC, open Google Chrome (not Firefox, only Google Chrome, because Google Chrome has cast feature), open a video on Youtube, then you should see the cast button that can cast to your ChromeCast.
There is a useful article about this.
New discovery, I was wrong. Chromecast does work over Ethernet cable. I can cast from my smartphone to my Chromecast when my Chromecast uses Ethernet and my smartphone uses Wifi. (Note: my Chromecast is actually a TV Box that runs Android TV 10)
The reason it didn’t work before is that my cousin incorrectly setup the wifi’s Router IP address: My house has 2 routers, the main router doesn’t enable wifi, the secondary router enables wifi, but the IP address of the 2 routers doesn’t match (main router (ethernet): 192.168.1.1, secondary router (wifi): 192.168.3.1 –> doesn’t match so here is the problem).
I have to re-setup my routers to make the IP address matches. To do it, I follow this video instruction “How To Connect Two Routers On One Home Network Using A Lan Cable”: https://youtu.be/J5QJb3O19zI
I recommend you to watch the video instruction to setup the routers, here is the general idea:
Main router: IP Address: 192.168.1.1; Enable Use Router as DHCP Server: [192.168.1.20, 192.168.1.254].
Secondary router: IP Address: 192.168.1.2; Disable Use Router as DHCP Server.
Connect the Secondary router to the Main router: Main router's LAN port <----LAN cable---> Secondary router's LAN port. Note: plug the LAN cable into LAN port, not WAN port.
