Deco P9 slow internet speed
I have just bought a box of the 3 deco P9. I have them connected to a virgin super hub 3 set to modem mode.
I should be getting 200mbs from virgin but I'm getting 110mbs at the hub (when in router mode).
when I connect the main deco I'm getting anywhere from 2-20mbs that's a big drop.
I have the next deco in an adjoining room, around 10m away. It generally connects ok to that. Then I had the other on the 1st floor but in an extension. Signal kept dropping so I have now hard wired that deco to the main one via a TP-link 8 port switch. Them two both seem to work ok except speed isn't great. The 2nd one has been dropping the connection all day to the point where I have had to turn it all off and set the virgin hub back up. I'm working from home do can't afford for it to be dropping all the time.
any ideas why the connection speed is so slow from the hub to the main deco.
I used the Ethernet cable it was supplied with.
all decos are plugged in at the wall and not extension leads.
any help would be greatly appreciated
