attached screen shots from previous post also show vids are the same. SSIDs 1
and 2 are connected to the same vlan.

Currently, 5GHz networks are not compatible with Chromecast which is likely why
you're not seeing it.

I knew you were going to say that.. Please.. Please read the ticket thoroughly
and escalate if necessary!
I'm going to re-iterate:
I have a DUAL BAND AP
One Band (ssid1) is 2.4 Ghz
The other band (ssid2) is 5.0 Ghz
BOTH ssids are connected to vlan 1681
I have two clients and 1 chrome cast.
The Chromecast is connected to ssid1
Client 1 is connected to ssid1
Client 2 is connected to ssid2
client 1 can see the chrome cast
client 2 cannot.
again - BOTH ssid's are on teh same subnet/vlan
I expect to see the chromecast from either ssid.
PLEASE review diagram and review case throughouly
I am NOT trying to connect the CC to a 5.0Ghz SSID.

Additionally I can see the CC from client 2 IF I move client 2 to ssid-1

Please try upgrading Linksys firmware or rebooting AP. This issue is not on
chromecast side.
This is a problem for Linksys that traffic can't flow between 2.4GHz and 5Hz.
You can test it through below steps:
- Connect your phone to 2.4G and laptop to 5G. Ping from laptop and to see if you get reply.
- If you have Apple product, connect it to 2.4G. Connect your laptop to 5G. Ping 224.0.0.1 to see if you have reply.
Hope this helps.

Hi -
1 Firmware has been upgraded to latest code.
2 Traffic is not engineered to flow directly from SSID1 to SSID2 - I tried to
be clear in diagram however it appears to be non-obvious:
2a imagine a scenario with two SSID's plugged into a single switch (VLAN)
2b SSID1(2.4) is virtually plugged into switch port 1
2c SSID2(5.0) is virtually plugged into switch port 2
2d packet from SSID1 is received on switch port 1 and forwarded to switch port
2 for SSID2 destination.
Packets ALWAYS traverse switch.
3. I can ping phone to laptop in your test. I do not have any issues.
3a when I ping from phone to laptop in your test, both mac addresses get
learned on the switch from point 2 above.
Conjecture that Linksys that traffic can't flow between 2.4GHz and 5Hz it
totally incorrect.
Please escalate.
