Solid Walls = no wifi, buying options?

So i moved into a 'new' home a few weeks back. It's actually a victorian terrance house which hasn't been opened up yet so there are solid brick walls everywhere.

This is nightmare for my Wifi. I've just got the Sky standard hub, and it's good enough to cover the living room and up through the ceiling into the bedroom above, but the signal cant get through ANY solid wall. If you go in the dining room, kitchen, bathroom, ANYWHERE else in the house basically, your phone will switch to using 4G.

I want to set up a mesh network in the house. Ideally, i think, given the solid walls the best solution would be powerline wifi extenders but i cant find these easily and when i do theres no mention of them forming a mesh.

Has Powerline fallen by the wayside? Would i see much benefit from Wifi 6?

Typical usage:
A couple with a small child so -
4k Netflix etc, 2 people working from home, lots of zoom calls, only occasional (sadly) online gaming (Rocket League mostly). I would imagine 'peak' usage might be my wife watching netflix one evening and me playing RL upstairs.

We also dont want 'ugly' AP's dotted round the house so i have been looking at the Google Nest Wifi option as a solution but i'm unsure of its signal quality.
 
What on Earth is your house made out of? A modern routers wifi should happily pass through a few brick walls yes signal and speed will drop but I’m staggered it doesn’t work in the next room!
 
I would try and get CAT6 ran but if not, I currently have Huawei Q2 Pro's (2 bases, 2 satellites) in my house. Built in the 40/50's, very thick solid walls. Uses powerline or "PLC" or can use Wifi if it feels it's faster. Have 140+ everywhere (even the garden). I feel like the speeds go up to 300+ if I restart it every few days. But I never feel like it's "slow". Seen online that it can be had for £50 for a base and 2 satellites. Not wifi 6 but honestly don't really care as I never transfer anything internally.

Edit: They also look really modern and blend in on the radiator cover I have my house phones etc on as I walk in. (I know my house looks **** but the Q2 Pro's look good, the blue light can be toggled on or off in the app.)

Don’t you have floorboards or are they concrete floors?

Yes, and this is why the location with the next best signal is the bedroom directly above the router.

I'm testing out the TP-Link Archer AX50 Wifi6 Router with a couple of their AX1800 Wifi Extenders. The extenders will arrive today but i've had the router for a few days now. At the moment i've had to set the router to just be a WAP plugged into the Sky router as i cant for the life of me get it working with my Sky FTTP. The signal from it is excellent though and it gets, maybe, double the distance. But that still means the signal drops out half way through the kitchen and still doesnt reach the bathroom (directly above the kitchen). I will be plugging the extenders in, in the hallway and landing sockets so should get good coverage on both ground and first floor i hope!

As an aside, if anyone can help get the AX50 router to work as a router with Sky FTTP i'd be eternally greatful. I have used Wireshark to get the username and password out, (interestingly NOT the generic ones which are widely mentioned on various forums on this topic), but still no luck. TP Link support tell me i need to ask Sky for some VLAN ID too.

Finally. Regarding the walls, I was talking to someone the other day who said the walls are all made up of some sort of coal waste product. A quick google search makes me think this is "Fly Ash Brick"

You can drill through any wall in any house if you really want too. Still shouldn't be a problem as long as you own the house out right ofcourse.

I have had the same problem, as I have double extension and so a few rooms sit on the ouside of the original exterior wall, Wifi does not pass with any performance, I solved it with a mesh wifi setup initially positioned through doorways and perhaps through an interior wall or ceiling, I just used Huawei AX3 which were ~30-40quid each this worked well except for topping out at about 300Mb under load to NAS at far points, which may be enough for you, I wanted more so I added some and some wiring of backhaul to the routers where I wanted performance and it has been amazing.

Some of my ethernet cabling is done by pushing an ethernet cable under the carpet between carpet grippers and wall but also being a flat ethernet cable can actually just be squished down the side of carpet and the only place you'd spot it is in door ways.

As for wiring in to the Sky hub, I just disabled the wifi on the Sky hub plugged one cable from sky hub to my wifi router wan port and that was that, I may have set DMZ on Sky router for new router but nothing more complicated than that, been running all year no issues serving web stuff, multiple VPNs etc and good latency. Looks like your AX50 is similar no modem so you need to use the Sky to serve the AX50 WAN port and put the AX50 back in router mode then server all your devices from the Ax50, there shoudl only be one device connected to the Sky hub.

No modem mode on the Sky router so no other way to do it short of buying a modem but have seen no drawbacks, well actually one drawback was the Sky minis, they are a bit unreliable on mesh satellites, so I used some cheap powerlines to feed them from Sky box but would not use for main internet in my house at least because the rings from main house to extended bit only got about 40Mb through powerline, if I used two powerline in extension or two powerline in main house without the crossover the powerline would do >500Mb, so if you don't have complicated wiiring powerline might work for you, I mean even do my detached garage 30ft at the bottom of the garden I can get about 300Mb with power line so it can be handy if you are all on the same circuits.

Our house rufuses wifi like yours. I hard wired cat 5e cable to 4 locations around the home. Then four Tp link Deco units each HARD WIRED broadcasting a mesh network. From poo wifi to nearly 100% full all over my property. What's in my walls I don't know any wireless signal is pretty much killed from room to room here without a mesh system, and a mesh that's hardwired to the modem/router I have.
