Chromecast on TV can be connected via iPhone, Android phone, and google home device, all via my home wireless network.
Chromecast cannot be found from any of my 3 laptops via same wireless network, the scan from the CHrome browser doesnt find anything.
All phones and laptops can access the internet via wifi on the home network.
I can ping the chromecast device from the Laptop, as I found the IP by checking on the SEGEMCOM Optus NBN device.
They are all on the same class C network. The default 192.168.0.0 /24
MyOptus NBN wireless router is a SEGEMCOM Optus.
I also have a remote wireless access point near the TV (Chromecast device), cabled to the SEGEMCOM . Both have same SSID. DHCP is only on the main SEGEMCOM.
I tried with the PC connected to access point , and then to segemcom . No good both times .
Is there a setting I need to change on the SEGEMCOM settings ?
Is there a setting on WINDOWS 7 I need to change ? (I disabled the firewall on windows)
I dont believe I am using the 5G wireless interface, only the 2.4G, and the cabled ports.
I was going to ask about the 5Ghz vs 2.4Ghz. Are you positive you're only using 2.4? I run into this problem every now and then with some devices on one band and others on the other.
The alternative is, have you got the google cast plug in installed? Maybe try installing (or uninstalling and re-installing) that
I don't think it should make any difference whether your on 2.4 or 5ghz. I tend to use both in my house depending whereabouts I am and never had a problem. Both my Chromecast are on 5ghz and I can connect to then with my phone on 2.4ghz or PC. But that said always worth a try.
Just confirmation from @RokerRooDave when you try to cast from Chrome you go to Chrome settings and then click on cast and your Chromecast device doesn't show on the dropdown Cast to?
Yes , nothing in the dropdown when I click the cast icon on the laptop.
I also try using the URL : "https://www.google.com/chromecast/setup/" from CHROME Browse, and select "set up your Chromecast", the scan attempts to find the chromecast be never does.
Will try re-installing the chromecast when I get home tonight.
It sounds like your second "Access point" isn't acting as an AP but as another router which is physically separating the networks apart.
