Unable to connect to wifi network after a while connecting tv to network and using IPTV

Installing and Using OpenWrt
1

I have a problem when using openwrt 21.02. After a while connection TV to network and using IPTV function, then other devices cannot connect to the wifi network.
After disconnecting TV from network, other device can connect to wifi network.

Can you give me some some advice in this case?

Thanks in advance,
