New Wifi setup

[Ozzi]

Hey Guys
First of all i dont understand wifi but here we go

So we just opgradede our wifi speed from 500/500 to 1000/1000

our current setup is like 7 years old and was bought when we got 500/500

ISP-box to Google Nest to Switch to Tp-link M4 deco (primary)

for me it seems wired that we cant cut the google nest part out, which we also are getting a replacement for snice it doesnt work right after we got 1000/1000 (dont ask) so i got 2 questions

1. Can we cut the google nest or its replacement out and just go straight from ISP-box to the Switch

2. as far i can tell from the spec on the M4 it cant handle 1000/1000 what would be a good replacement for that

Without knowing what your ISP box is, we cannot tell you for sure if you can do ISP box > Switch or not.

Who is your ISP?

First of all i live in Europa 
and our ISP box was set up a long time ago but according to google its is ONT.

It's basically masers straight out of scifi

By this I assume you mean that you upgraded your service plan from the ISP, not the wifi itself

That's.... a decision You've got three routers there. Two I understand, the ISP combo box usually isn't the greatest, but three is odd

You absolutely can

Yes, or you can keep the ISP box in modem only mode and allow the TP link system to be your router

It *can* handle gigabit. It just doesn't have the capacity to provide that via wifi because it's limited to wifi5.
If you wanted to upgrade to something that supports wifi 6 or even 7, you can do that, but honestly, if you aren't having problems with the speed currently, I'd say just keep it. Anything that needs more than the 400mbps that you will typically see on a good wifi5 connection should be hard linked anyways

I'm not sure you're fully aware of how getting wifi into the house actually works, but a typical chain works like this:
The cable comes into your house from the street or wherever and plugs into your Modem (your ISP box in this case). That modem is the wall between the inside of network and the internet itself, but it only has 1 IP address. That then connects to a Router (often also included in your ISP box but also your Nest and TP link can function as routers) which takes that 1 public IP address and allows a whole bunch of devices to use the internet though the pipe provided by the modem. Then the router is typically linked to a Switch (often there is a switch built into the router) which splits out to multiple ethernet jacks for anything you want to hard wire. You then connect one or more WiFi Access Points (APs or WAPs) which will allow devices to connect wirelessly. Usually the ISP box also has an AP (the fact that they are modem, router, switch, and AP is why they're commonly referred to as combo boxes), and your Nest and TP links can act as APs.

Okay i have basic understanding of how wifi works 
If i remeber correctly, the reason why our network setup is the way it is, was becouse it was the only way it would work. 
And to give you an idea of where the differnt links are placed in the house 
ISP, google Nest and Switch along with one Deco are in the basement 
Main Deco is the living room on the first floor right next to the TV (we have streaming tv box which means we need wifi for it to work)
The last Deco in my room which is on the second floor as i use ethernet to my pc. 
the reason why the main Deco is not basment but on first floor is becouse between the bassment and first floor there is thin layer of tin foil more or less which kills the signal. but we have a cable in the wall from the bassment to living room

But if am reading it correctly we should just be able cut out the Nest and plug the cable from the ISP box straight into the Switch Which would send the signal to the Main Deco Yes?

No, the ISP box if it's a ONT is NOT a router and the first thing plugged into the switch will get a public IP address and everything else will have no connectivity. You need to go ONT > Router > Switch.
