Netgear R8000 slow when connected to Sky Hub via LAN port

[Rockingit]

We've got 'standard' 40/10 FTTC fibre into a Sky SR203 router, which all works fine and we get speeds around 38/8 at the Sky Router.  I've laid CAT6 to an outbuilding where it's connected into a Netgear Nighthawk r8000 predominantly to run some security cams that the WiFi just won't leap as far too, even with extenders.  Sky Hub is acting as the DHCP server in the 192.168 range, R8000 has auto-sensed bridge mode and self assigned itself to the 10.0 range - and it works, there's three devices running off it now.

Except, the R8000 is reporting a speed of 8MB/700Kbs, which just can't be right.  It should either be 100MB LAN speed or at worst a tiny reduction of the Sky speeds, surely?  

So what's throttling it - Sky or Netgear?!  (NB, the CAT6 is fine, fully tested).

Sky cant/doesnt throttle speeds especially local speeds over ethernet. There must be something wrong with the cable or Netgear router or the way it tests speeds

"Sky cant/doesnt throttle speeds especially local speeds over ethernet. There must be something wrong with the cable or Netgear router or the way it tests speeds"  @jamesn123  - thanks for this but I wasn't really questioning Sky itself, I was questioning the sky router.

@Rockingit 

Have you tried connecting a device via ethernet to the Sky hub to see if speeds are correct then?

If they are you know its cable/netgear router related issue

[Rockingit]

@jamesn123, I think I've sussed it.  The Netgear simply won't recognise any traffic that isn't via its own WAN port, but views it as an ISP connection.  Remedy is to reconfigure it as an AP.

Ah I should've thought of that. In your original message I read 'bridge mode' and for some reason assumed AP. Yeah all secondary routers on a network should be in AP mode unless you are doing special network topology.
