A point in right direction to educate myself on UnManaged switch

I'm new to the switch thing and I bought a GS108V4 to add more lan lines and to run another wireless access point. I'm hung up on not wanting to run a straight line and want to make 3-4 separate groups. I have 3 lan off my wifi6 router but only want to use 2. Should I use my switch in-between the modem and router or use a older router as a switch in-between the 2? And I really don't know much about managed and unmanaged but from what I have read on so far I'm thinking I bought the wrong one thinking I was able to put different securities on the unmanaged switch I thought the managed had all the security preloaded on it can you still mess with the security on and on managed switched through an IP? I can't seem to figure out how somebody keeps getting into my network even with nothing hooked up to any internet and changing my system and apps as hope and throwing a switch on there in a few access points and separate and things might solve the problem. Thanks in advance.
  • Neither your router (wild guess) nor the switch does support a correct isolation of such two networks. Just different IP subnets don't bring any network segregation. Where do you intend to run any kind of routing? It's not so simple as the school theory implies.

    Even if your router does offer multiple network ports, if your old re-purposed router has multiple network ports, if your un-manged switch offers multiple ports: Most consumer and soho devices operate on one network, one LAN, one IP subnet, one broadcast domain.

      That is true but with the subnet you can break off multiple networks with a completely different IP address so if IP #1 starts with 192.168.1.1 than you can use 10.70.14.4 as your second the iso allows 255 IP 4 numbers are used for router 1,4, I think 11 and 254. So manually assigning net 1 with a end isp with say 60 with the DHCP than it would cut off at 60 the rest you can use for a different net. I watched 2 videos on it. And was told on LinkedIn it can be done if you branch off in-between modem and routers
