Hi, it sounds like you have the right setting.
Now I have found lowering the bitrate down to 6 on that SSID on the "Access Control" has worked wonders on Chromecast deployment.
I really can't explain why sadly, it is just something I tripped over. Hope this little tip helps.
Something else, is the Win10 and Chromecast on the same SSID? this helps, but if bridge mode is on, it should work even if on different SSID's. Are they on the same VLANs?
Setting I have used
- Separate SSID yes and dis-similar SSID have worked.
- Bridge mode yes
- Band Steering disabled no (I leave it on an drop the bit rate to 6Mpbs)
- Multicast to Unicast conv disabled (also tried enabled) ( I leave it on Multicast haven't tried this)
- MR45 (MR42,MR32,MR56) never tried it with a MR45
- Rls 27.5.1 yes
- 802.11ax disabled (also tried enabled) (I leave it on but, have tried this)
they can be frustrating.
