Yes, if the router won't let you change DNS, then you'll need to do it on each device.

Not sure if Sky hijack the DNS ports and reroute requests regardless of DNS server requested.

If you've set your own DNS in a PC, say, then any demand for a DNS lookup on the PC will result in a IP addy. By the time the packets get the router there's only raw IP addys & there's nowt for the Sky DNS to look up.

Surely Sky could still intercept the requests.
Say PC is configured to access Google DNS on 8.8.8.8:53
PC sends off DNS enquiry to 8.8.8.8:53
This gets into Sky's network.
Something in the network sees traffic for port 53, intercepts it, extracts the enquiry, satisfies it from its own DNS, and sends back the reply.

Now, if you tunneled the requests out over a VPN to something outside Sky's network, it should work. But a Google search seems to indicate problems.

So, another call to Sky and they said they'd send an engineer around as they found a "non-specific fault". The engineer appointment was not kept, and no phone call to say why or if he'd mended an external problem. Poor show!

But, I'm 99.99% certain that the problem lies within onedrive that was recently installed on a laptop (not mine). I'd pretty much narrowed it down to the laptop, and then saw the network activity as onedrive was trying to sync about 14,500 files at about 16GB.
I've now set a download/upload cap in onedrive's settings.

But the culprit must be poor traffic management within the Sky Hub router thing.

Maybe you have created a network loop in your LAN and the packet storm is overwhelming your network.

What traffic management? Most CPE have NONE.

OneDrive will be uploading multiple things at once and saturating the upload if allowed, and the side effect is that ACK packets are delayed for material you are downloading.

The effect of this is visible in our speed test http://www.thinkbroadband.com/speedtest and click the Analysis button and you can see how latency varies when idle, downloading and uploading, the latency is measured with a small TCP packet so dependent on ACK reaching

Came across one of those the other day at work..... didn�t realise it�s affects had a proper name ..

�Network storm� I shall remember that next time and sound all informed when I tell the punter

Do you have the Sky Q Hub? In my home on the Sky routers my 2.4Ghz often becomes virtually unusable. Weirdly never had the same issue with BT routers.

Using the 5Ghz solves it, but often whilst 5Ghz is working I cannot even browse a page on 2.4Ghz.

You need to go to 192.168.0.1

Click Wireless

On 2.4Ghz network settings, change the Network Name (SSID) to something new.
Untick Synchronise 2.4GHz and 5GHz Settings

Press Apply.

Your 5Ghz network will now be named the old SKYXXXX SSID, your 2.4GHz will be named something else of your choosing. Stick to the 5Ghz one, how do you get on?

Note some devices may not support 5Ghz and hence not even see the network. These will need connecting to the other SSID.

Do you have a Sky Q Hub? These devices do manage traffic, ensuring one device cannot take over. The net result is each device does not max out the connection though, which some people moan about.

I haven't got the Sky Q Hub, just the SR102 (I think it's called that. The black box).
Maybe if I plead to Sky they'll send me one.
Does the Q allow you to max out your internet connection for just one device (if nothing else is using it)?
