Get online support
google chromecast is not working since i updated my home network from 4g to 5g wireless broadband, i contacted tpg and did some changes to sagemcom wifi router configurations. still doesnt work, but the chromecast used to work fine with 4G wireless tp-link router, and same chromecast is still working with 4g network at a different premises, i tried settiing with 3 different devices and 2 different google chromecasts. during the set up process Home app able to detect the chromecast and connectb but at the end get the message in quotes
" cant see the chromecast on this Wi-Fi network. check that its online and that your phone or tablet is connected to same wi-fi network"
despite using the same network during set up process,
i am told by TPG that unfortunately the only router provided for 5G wireless broadband service(sagemcom router) is not compatable with chromecast. is that true?. after spending few days on it, im still not able to fix the issue.
Hi @kannarakesh05 . What changes did you make to Sagemcom wifi configuration?
@kannarakesh05 . Regarding the ssid names, did you check that your phone or tablet can connect to both?
Do all devices show up in Sagemcom as being on same ssid?
Do the names have any special characters? Can you try them with just letters and numbers.
Does chromecast and your devices have a function called Wifi Direct enabled?
Do any devices have a connection to chromecast?
@kannarakesh05 . Can you try this as a test.
Do you have a tablet you can connect to the same wifi band as your phone?
Connect both to the same wifi band.
Activate Wi-Fi Direct on each device. Make a connection from one device to the other.
If they can't connect, there is something in the way the Sagemcom operates that prevents the connection.
And probably prevents the Chromecast working.
If you have the old 4G router, can you connect your phone and Chromecast to it (internet connection not needed). Note down the Wireless settings and Advanced Wireless settings:channel and channel width, beacon interval, RTS threshold, DTIM interval, group key update interval (whatever of these items are displayed), and compare with Sagemcom settings.
If you have the old 4G router or some other known good one, you can use it as access point for Chromecast. Use the 2.4GHz band here and disable 5GHz band. Disable 2.4GHz on Sagemcom and use just its 5GHz band.
It would be really nice if TPG said why this doesn't work!
Hi @rrajagopal . Do you have different SSID names for both bands?
Pixel5 works with Chromecast, but laptop, iPad and Pixel6pro don't?
In Sagemcom admin, are all devices on the same band?
@rrajagopal . On the ipad and phones, in the wifi settings, is there a Wi-Fi Direct function?
If you activate it on each device, do they see each other?
Can they connect to each other?
