Hello Everyone! I went to the customer and now it is working, I thank all the comments you gave me, there was nothing involved with the problem we had. the fix procedure we found was:   - disable all firewall and antivirus software from the windows computer. - disable/enable the wireless adapter - Connect to the network, try to cast, it works. - enable firewall/antivirus software - the cast still working - we also reboot the computer, and the cast still working.   The parameters of the configuration at Meraki are: - Separate SSID yes and dis-similar SSID have worked. - Bridge mode yes - Band Steering enabled  - Multicast to Unicast conv disabled  - MR45  - Rls 27.5.1  - 802.11ax enable      thank you all!!  ...
