I have a 3-pack of the TP-Link Deco P9 model. According to the product specifications, it should provide speeds of up to 800Mbps, but the devices are only delivering a maximum of 200Mbps.

When I connect directly to my internet modem via cable and run a speed test, I get 970Mbps, confirming that my internet service provider is providing 1000Mbps. All my devices and the mobile app have the latest firmware and software updates installed. I also reset the entire network and set it up again, but the result hasn't changed.

Any suggestions on how to resolve this issue?
