WiFi challenge 3 floor Victorian property, approx. 170m2

Hello,

I wonder if I might get some advice on this fantastic forum. I've live at home with my wife and one son. We've got some 30+ devices in the property not all in use at the same time. (although we've some security cameras/Synology nas on the same shared Devolo structure live all the time using some bandwidth see below).

Problem - I've been having issues mainly sharing the screen content via my S23Ultra mobile phone with a well known streaming service to my TV in our living room. (Using the 'Smart View option to local device feature in Android) . Some nights the performance is good others not and believe it's down to the home WiFi connectivity in the living room not connection speed to the home as all other services work fine including apps on the phone and set top box. Of course the resultant WiFi performance in my case is a combination off local performance of the Devolo unit and it's overall service provided by our router via it's mains connected link I see a very strong signal on my phone in the living room but that's signal , internet speed tests run at 60Mb/s . (but 250Mb/s in my 2nd floor office via the router.). I'm supposing 60Mb/s isn't enough to serve the phone and then back to the TV?

The living room has one of the Devolo 1200 family WiFi devices 2.4 and 5GHz as well another with triple 1200 adaptor with sockets to feed the TV , cable TV box, and WiiM streamer / preamp.. We've a D-Link 882 router bought about 6 years ago following a great review on this very site and a six Devolo 1200 family ethernet over mains devices on the ground floor to route data to the TV's , Internet radios, HiFi... The router is situated n the 1st floor (fed by a 1GHz Virgin cable connection (1G down/100MHz up service)), the Devolo ethernet devices provide cable connections via a single wired link back to the router. i.e. the Devolo devices all feed from a single port on the D-LInk router.
I'm taking an educated guess that my router is now behind the curve in terms of performance. However when in the living room my Cockpit app (Devolo) shows of course my phone connecting to the Wifi unit on the mains at 5Ghz. So in this regards a better router in the same position won't help unless there's bandwidth limitation via the Mesh devices and router combined. I'm finding it tricky to get any specific facts to tell me how to move forward at this stage.
Do we think this is a (a) a technically poor solution and if so what to move to (b) might I improve connectivity by upgrading the router alone or (c) going to a complete new Mesh solution. I've read there's good and poor Mesh linked units. Some without dedicated 'back' radio channels not being so good. Don't want to spend more than I have today as budgets are tighter following retirement ...

Hope this isn't too complex. Thanks in advance for reading.

Is your phone connecting to the TV via a wifi frequency (2.4 GHz or 5 GHZ) or over Bluetooth ?

Is your phone pulling internet stream over wifi or over LTE (cell) when you see the issue ?

If it is all over wifi ( internet to phone, phone to TV) then the available bandwidth will reduce by at least half as the phone is acting as a repeater. LTE can be all over the place for bandwidth.

You could have interference in the wifi frequencies or on the power mains ( electric motor running for example ) also.

The stream from the internet provider could also be having issues, particularly at common watching times, via the cable provider ( cable to an area is a shared resource) or the streaming company.

Hello, I can answer some of your questions:

I believe the phone is connecting to the Devolo at 5GHz, not sure how I can tell what Bluetooth is doing. Surely the latter isn't used for transmission of a 4K Video stream to the TV?
I believe the phone is pulling over wifi not cellular as it auto connects in the home to Wifi ( I did try toggling that I think)
I don't think it's the servers/cable , normal service either from an app on the phone or via the set top box is rock solid .
it's really the use of the mobile phone serving to the TV , hence my questioning how good the wifi arrangement is.
