EE Smarthub - Capping use of Submix App

MattDuke0 — Wed, 17 Jun 2026 08:12:35 GMT

Hi There

I work for a start up called Submix, we provide studio grade audio and video of an online platform. I have had no issues with any provider or device until I connect to my EE smart hub. It seems to cap the speed of the platform rendering it unusable. I've done a multitude of testing with the wifi optimiser and ping optimiser and neither provide a stable solution. Is there a way to turn all capping or traffic limiting off the router.

Product code:

SH31B

Firmware version:

r3.8.30-R-1627300-PROD-83002

Mod note: Removed serial number from public view

@MattDuke0 Consider going out to get your own Hub then but you connection type will define what you need to look at, nothing else.

EE apply no Traffic Management to their Home BB network.

What is the name of the EE BB plan you are on including its speed?

How is the speed apart from your app?

Thanks for the reply!

I have Full Fibre and have tried different hubs along with wired and wireless connections. We actually moved property and the problem moved with the change. The issues has been the same in both properties.

Plan is - Essentials: Full Fibre 300

Last speed check - 260Mbps Down, 69.4 up, 18 Idle (Jitter 3) 134 Download (Jitter 42), Upload 27 (Jitter 9)

The software worked flawlessly with a previous provider. Currently my solution is to run it off 5G during calls.

Thanks

Matt

@MattDuke0 Have a look see if your software is running IP as IpV6 in operation, there appears to be some particular issue and a few have disabled that currently in the EE Hubs, Not sure if there has been any changes to your hub FW wise but to do as required it would all be in advanced settings to disable it, worth a try and see how it goes. There is a round off FW updates for the SH31B you have so linked that below if you need to compare. Forget about the Ping optimiser sugar it does not look like it's working 90% off the time. EE do not admit to any traffic shaping but will post the minimum that OR applies to your profile... FF300 product is rated at the 330/110/50 all Mb/s when the system gets into the busy mode traffic wise.

FW: r3.8.30-R-1627300-PROD-83002 and the gui is at App version 3.1.18 05/12/2025
FW: r4.26.1-R-1860948-PROD-83002 and the gui is at App version 3.14.5 25/05/2026 OP Posted Stability Problem
FW: r4.26.3-R-1923144-PROD-83002 and the gui is at App version 3.14.5 12/06/2026 OP Posted

I use Asus and on the EE connection when i had it saw NO IpV6 issues but once pinned back to the FF500 connection at the 200Mb/s rated limit, did not have any issues as plenty headroom speed wise at the time.

Thanks so much, will try some FW updates and see how that goes. Its so strange as it runs fine on much slower connections, have tested it right down to 20Mbps and as I said its stable on a 5g connection when I hotspot. I also tried a couple of other routers in various brands and they did the same.

@MattDuke0 EE control the FW updates to the Smart Hub 6 + that you have, generally overnight in operation when customers are asleep, it may just pop in anytime within the next few weeks so all you can do is keep the eye on it for happening. Do you currently happen to have a BT Smart Hub2, if so would throw that on the connection as it's an easy one to do and no faffing about with it.

Did some more testing this evening, toggled IPv6 etc no joy. Tried logging on to the public 'EE Wifi' that my router is sending out and it works! Any ideas?

@MattDuke0 Really do not know anything about your specific app sharing profile or what is actually required for it to operate in a successful manor. If the EE WiFi app logon is working for you then just use it. You can also just wait and see if the FW update does anything to help you out on the other WiFi profiles. You have a mixed bag going on with and if purchased the addon for Optimisation of the EE Hub.

@MattDuke0 - does the software attempt to prioritise traffic with DSCP markings or similar? If so, have a read of this and this.

TL:DR - you could be hitting an acknowledged issue with some EE hubs where they are not stripping the DSCP markings applied by third-party applications. This has the effect of stuffing the impacted traffic into a prioritised queue that has very little bandwidth allocated to it.

As others have alluded to, r4.26.3 firmware is currently doing the rounds which may well contain a fix for the problem. It would certainly be interesting to see if you still have problems once you've received it.

Interesting, we use Livekit library but we don't have any DSCP markings.
