SkyQ box throttling speed?

[Lorraine2404]

Apologies in advance for the long post but want to share as much info. as I can!

I recently moved from Virgin back to Sky as Gigafast is now in my area. I was on M500 with Virgin and download speeds were really good, only issue was Wifi was patchy and lots of dropouts and CS werent helpful either. Sky Gigafast seemed like a good idea as I could get faster speeds for less money.

However, I am getting nowhere near the speeds I should be and I think the Sky Q box is causing it!

My setup is:

Sky Router in my Study and 2 ethernet cables connected to that which are connected to a network switch in my loft (the previous owner had most of the house wired so I have ethernet cables in most room) I also have an 8 port connected to the router as I havce quite a few devices in my study and not enough ports in the sky router.

When I had Virgin I was getting around 400 - 500mb/s download speed in all rooms via ethernet now moving over to Sky with devices plugged in exactly the same as before I am only getting 150 - 200 mb/s via ethernet.

I put an Xbox in the study connected directly to the sky router and straight away it was downloading at around 700-800mb/s as I would have expected, plugging this back into ethernet upstairs and went back to the 150-200 mb/s.

I read somewhere that the Sky Q box could cause problmes so I unplugged all mains plugs from the Sky Q box and the 2 minis I have just in case.

Went upstairs and tested a download on the box and lo and behold it was around 600-700mb/s!

Plugged the Sky Q box back in and turned it on and it immediately went back to 150-200mb/s.

I turned off the 2.4ghz 5ghz wifi on the Sky Q box but that actually dropped it to between 0 & 15mb/s on the Xbox! I turned the Sky Q box back on and tried unlpugging the ethernet cable from the SKyQ box but again this resulted in 0 - 15mb/s download on Xbox. It must be something to do with the Sky Q box but have no idea how to fix it? 

Basically it seems I have to leave the Wifi on & have the Ethernet plugged into the Sky Q box as well to get the 150-200mb/s but thats nowhere near where it should be,

My Sky Q box is about 6 years old (Model 32B107) is there a newer model that may help, but the odd thing is though with Virgin it was the same setup just using a Virgin router and speeds were absolutely fine.

Thanks for reading and any help would be much appreciated.

It is a known issue and is caused by LAN storms, this is because there are 2 routes to the Sky Q boxes one by ethernet and another by wireless, and data packets get broadcast and rebroadcast by the two routes simultaneously, eg: Sky Q boxes and ethernet storms together,  one route sees the packets passes it to other route and that try to rebroadcast with both routes looping.

Either run the system on ethernet only and disable wireless on Sky Q boxes involved or use wireless only for Sky Q boxes without ethernet connections. 

Alternatively, upgrade the system to Sky Stream...

Thanks for the reply, I had tried that both ways so either WiFi disabled and using ethernet or cable unplugged and using WiFi which unfortunately neither worked..

After some more reasearch I noticed a couple of people had bought a new router so I decided to get a tp-link one today and give it a try and happy to say so far so good. Download speed on Xbox is now up to 800mb/s and WiFi seems stronger too.

Hopefully it will stay that way!
