Model: Deco M5  
Hardware Version: V3
Firmware Version: Deco M5_V3_1.6.1_20220818

I recently installed Spectrum internet with 300 Mbps speed.  If I directly connect my PC to the cable modem, it can indeed achieve 300 Mbps.  However, when I connect the modem internet port to the Deco M5 Ethernet input, I can only obtain about 50 Mbps.  It is true for WiFi as well as for the wired Ethernet, even if I directly connect my PC to the M5 Ethernet output.  Does anyone know why and if this can be fixed?  Please let me know.  Thanks in advance!

It is very likely to be cased by the QOS on the Deco. Please check on the Deco APP whether the download/upload bandwidth has been limited to 50m/s.

Thanks.  Yes, this is the problem.  Thank you for pointing out.  
Another problem is that the M5's router does not work as well as the TP-Link C7 router.

Question?

I found that the same issue yet I currently do not have QoS enabled.

Can you give me some guidance?
