Wire a computer to the first Deco and do a speed test to see if it is getting the speed it should. If so, try placing the Deco units at a different location that is closer

@Tony I actually don't have a computer with an ethernet port... or at least one that Isn't stored.

I do have it wired to my xbox though.  I was getting 550mbs and 20 ping with hardwired with my old router and now I am getting 280mps and 40 ping with this deco unit.

Wireless performance is similarly reduced.

@AllenH 

The Xbox should be a good gauge. Go into the Deco and and set the QoS to Standard, also make sure no device is set for high priority (tap on the device in the device list).

@Tony thanks.trying that now.

@Tony took two devices off priority.

When I go to the qos tab I only see this: 

There is no ”standard" option.

@AllenH 

Thanks for the screenshot, I think the QoS exists in the HomeCare Decos.

If you were to power down the other slave Deco units, does the main unit still give you speeds that are slower? What speeds are you getting in comparison?

@Tony I have powered down both other units and only have the single unit connected directly to the modem. I have done a speed test with a single deco unit hardwired to a computer and the single old router hardware to the computer. There is a noticeable difference. The ping doesn't seem to get below 40 with the deco unit and the download doesn't seem to get above 350.

I'm not sure what else to do besides return these units. It seems that these are designed for threat of coverage and have some sort of cap on the max even when hard-wired
