Sky Q continually dropping connection to broadband network

[purcat33a]

I've tried the Q via direct ethernet to the DHCP router, via wi-fi through the P9  (assume you refer to this as a node?), via a daisy chain from the router , through an RJ-45 in the back of the P9 and out again through the second RJ-45 and in to the Q box. 

They all result in drop outs.

Yes that's a node

what about ethernet Q to node and NOT ethernet backhaul to the router, that's what I was suggesting.

Sisnyou have wifi disabled when you were testing every combination that used ethernet from the Q?

[purcat33a]

Indeed, all combinations were tested with wi-fi disabled.

Eliminating ethernet back haul may be difficult with the P9's because they automatically support wi-fi, ethernet and Power Line Ethernet automatically and I don't know of a way to turn the individual methods off. If I pull the ethernet cable out of the back they will probably revert to PLE - but I'll give that a go.

[Chodley]

Yeah pulling the cable out of just the one the Q is plugged into is what I meant.

So do they also have powerline enabled through their AC cables? That's neat.

I suspect there's something going on where the spammy broadcast traffic from the Q is being amplified by having so many nodes and causing congestion. Maybe not having such a quick backhaul will constrain it a bit. Clutching at straws.

So, I'll probably eat my words in a bit and regret printing this but ...

I disconnected the Deco P9 from the ethernet wall socket but left the second ethernet cable connected between the P9 and the Q box. - which is what I understood Chodley to kindly suggest.

I've run the TV, over three or three or more sessions with the network status constantly showing connected - which seems pretty encouraging. Download speed on the Netflix checker seems decent enough for HD (which is all we run anyway). Later on tonight we'll watch something properly and see if Netflix behaves.

For interest - the P9 was connected directly via an ethernet cable before and was showing so in the Deco app. Now it is connected via a combination of wi-fi and PowerLine ethernet instead. 

I would be interested in thoughts as to why things behave differently without an ethernet connection via an RJ-45 and through PLE instead - I can't envisage a race condition as I would expect a physical ethernet connection to disable a wi-fi and PLE mesh connection as the bandwidth should trump everything else.

Thanks again.

I thought it a good idea to give an update:

A few more days on and a few more evenings watching streamed TV and, so far, it's been excellent - no dropped connections that I have observed and no purple worms circling around waiting for content to appear.

So, thanks everyone, for your help, and to Chodley especially (who provided the answer).
