Slow Wireless Speed:

1. Disable QOS: Deco APP > More > QoS > Turn off QoS Completely. Or, change to standard, remove all priorities and set bandwidth to 1000Mbps.

2. Turn off the UPNP feature and SIP ALG feature in the Deco App Under: More > Advanced > NAT Forwarding.

3. Try other speed test servers or platforms since some specific servers cannot reach the full speed for wireless tests. The test here has approved that if the server supports TCP BBR, the download/upload speed would be better.

4. Download a Wi-Fi analyzer tool on your phone to check wireless channel interference. Crowded Wi-Fi channels will cause a severe decrease in performance.
