TP-Link T2600G-28TS Managed Switch Configuration: Assigning a Permanent IP Address with Netia Spot

Hello.
I decided to modernize my home network a bit and bought a TP-Link T2600G-28TS switch. When connected to an existing network, it works without any configuration, but you cannot log in to it because it requires a permanent IP address. Currently the network looks like this:



only the router (Netia Spot) is working, the rest has been disconnected (replaced by a switch). The switch has the address 192.168.0.1 and in order to be able to log in to it I change the network adapter settings to the address from the switch pool and automatically do not have access to the network content. And here is my question whether I need to reconfigure the switch to work in the subnet, assign it another address pool of one of the routers, etc. Can it be done in a different way using the device's software. Here is the link to the switch emulator I have:

Any tips and suggestions are welcome.

I do not understand why you put this picture - it's just that you use the network 192.168.3.64/28? If only that, then simply address the switch with one of the free addresses from this subnet, and that's it ...

You are right, the simplest solution and it works. Because I no longer need 4 subnets and 4 routers, I reconfigured one of them to 192.168.0.1/24 and I assigned another switch to the free one, i.e. 2. I would like to ask how to assign a fixed IP to devices (computers)? Some of them will work on the switch and some will log in directly via wi-fi to the router.

I understand that you always want to allocate the same IP from DHCP - still routing probably controls your network in your network, so if it has the ability to assign / reserve IP to the host MAC, the easiest way to do it is on it.

That's right, I have a router, unfortunately ADSL. In addition, it is a netia spot. Configured by MAC + IP recommendations and works. Thanks for your time, that's all for now.
