EE Smart Hub + continuous drop out

[Saintmatt]

Good evening, grateful for any advice etc on the following issue

i have an EE smart hub+, since changing from BT last year. I have FTTC so it is the old copper connection to the hub.

i have 4 Ethernet connections to this hub

1 is computer ( Mac mini M1)

2 is BT whole home WiFi mesh 

3 is sky tv

4 is Hive

all worked fine before on old BT smart hub 2 (didn’t have hive and had a pc not Mac back then), problems started about 3 months ago and have got worse - Wi-Fi drops then shortly after all the Ethernet links go, yet the lights remain aqua green on hub.

several engineer visits later, line problems have been identified and fixed (apparently), yet problem still happens almost on an hourly basis and need to wait or reboot and the cycle repeats. The last option is to change the router, this has not happened despite being sent 4. I am now the proud possessor of 2 boxed EE mart hub + (the FTTP version so does not have the broadband ‘in’ port) and 2 BT smart hub 2’s because they can’t seem to send me the right EE hub. 
before I bite the bullet  and revert back to the BT hub (will need to purchase  a network switch as the BT hub only has three Ethernet ports), any ideas why the hub loses all connection, not just Wi-Fi? I get that there might be Wi-Fi conflicts, but to knock the Ethernet link out as well?

Wireless mode: is on the Advanced Settings > Wireless page.

@Saintmatt You will find it in advanced, wireless mode, then set and save the option.

Found it thanks, I have made the change and will report back

Reverting to Wi-Fi 5 , I may as well use the BT smart hub 2 lol

With your speeds you probably don't need WiFi-6.

@Saintmatt It's more about finding out what makes your system stop falling over!

[JimM11]

@XRaySpeX Assume you are thinking only about his fttc connection only!

[Saintmatt]

I do hate not knowing why……

Apparently I have to wait till 2026 for FTTP unfortunately

@JimM11 : I'm talking about OP's existing G-Fast connection. When & if he moves to an FTTP plan with faster than G-Fast speeds it will be a diff ballpark with a whole lot of new issues. I'm trying to help with the current issue!

@Saintmatt I have copied the link to the BT Wholehome wifi from BT site, and you will find the manual and spec's, also document if you need to download. Do think that they are wifi 5 rated as were made prior to AX wifi 6 being available, but they do seem to be a pretty good mesh unit. Also as i do not use them not sure if the relationship of were you have the primary unit sitting to the main EE router is, if the manual recommends turning of the wifi signal on the router, if it did, but will have a quick read through it. 

Edit: see that they are WPA2 AES, so you should also look at the router for wireless security and check its set for WPA2-Personal.
