If you have a wired computer steal the cable from the Deco that goes to the modem, and test that speed to make sure the slowdown is not coming from the cable or modem.

Start with the main Deco if that is only giving 60 Mbps, then swap the Ethernet cable being used, even if it is the one that came with the Deco, been swap to the second port of the Deco. 

When at the main Deco I would expect higher speeds, 60 Mbps maybe for the satellite units, but not the main. 

If speeds still are slow swap the main Deco with one of the satellite units.

@Tony  Thanks Tony, will give it a try. I did try a variety of ethernet cables when setting up the main node thinking there may be a fault, but all seemed to be the same. I will try swapping the nodes about and see if it makes a difference.

@Kaiserchieftain 

Sounds good.

Another thing I forgot to mention is to look at the QoS menu. In that menu, you can set what your internet speeds are, and if 60 Mbps were set then it will create a bottleneck. I would manually set that number to a high value.

@Tony 

Hi Tony, my P9 hasn't got the QoS menu available

@Kaiserchieftain 

Do you have the Deco in Access Point mode?

@Tony  yep

@Kaiserchieftain 

The QoS is seen in router mode since you are in AP mode it would not be there. 

You mentioned changing the setting of the hub to the modem, but if Deco is still operating in AP Mode your hub should still be in router mode. If that is the case, you can wire multiple Deco units to hub. Wire a second Deco into the router and connect to that with an Ethernet cable, and test those speeds. If both nodes are giving 60 Mbps switch the Deco back to router mode, check the QoS, increase the number if needed, and test again. If the wires speeds are still slow remove the Deco from the Ethernet cable and connect a computer to it. If bypassing the Deco nodes gives the full speeds try defaulting all the nodes, and setting it up one more time.
