Dear Support

I'm facing an internet speed issues when I connect my IPhone11 to the Wi-Fi 5G. 

For example when an Android Phone gets connected to the same Wi-Fi 5G the internet presents speeds of 200mbps for upload and download when I connect my IPhone11 I only can get speeds of 12mbs downloads and 90mbps upload when connected to same exact Wi-Fi 5G. I did this test with only my device connected to the router.

I tested the internet connection throughout wire connection and the velocity is around the same values that appears in the android device of my friend.

Nevertheless, when I connected my IPhone11 to another Wi-Fi router in my office the internet speed increases and overpass the values mentioned above.

Moreover, when the iPhone11 get connected to the router always alert me that it's a weak security. I already change the password and activate the DoS protection but the message keeps appearing. 
 

Is there any special configuration or activation that I need to do in the router?

Thanks.
