Hi  @WooJoo 

What's the encryption mode you configured?

Actually, the TX rate is 886mbps, which is already the highest the device supports. No need to worry about the wireless signal.

I'm using the WPA2 with AES. Max Support speed was 800 Mbps but the speed between the AP & Client is max 250 Mpbs.

Hi  @WooJoo 

The speedtest result you got here is the download speed between the wireless bridge. It's different from the RX rate.

To improve the speed, please have a look at the following guidance:

If the performance is not good, Please refer to the following articles to do some troubleshooting:
