Hi. clear.png

I could really use your help..

I'm trying to make sure I have a clean connection.(a clean eth) and I need to get it done really soon.

I have a new laptop and a new router.
My Q is:

If I don;t have a different network and share a router with someone at home, is there anyway of making the shared router and my laptop secure from other devices also using said router?

A guest option could be a solution? I have read sth about giving a different wifi pass to guests(or my brother clear.png) than the one you use. Can this possibly work for a connection via cable to the router also(for devices that aren;t mine and could possibly be infected), not just wifi? To make a guest option on my router for both wifi and cable connection to router from devices I don;t personally use. By this guest option I would separate myself from other devices I dont use(brother;s etc)?

If not possible, can I have two routers on the same network(same IP address?) And would that work to keep my router and laptop secure or does sharing the same network impose a security risk anyways?

Also, someone mentioned I should use a VPN.. would this solve the issue of sharing a router with other devices that are possibly infected and could infect me? 
I think it would make sure I have a clean network as someone could still have tampered with my connection somehow, even if I change router and laptop, but for the router itself and my new PC's security, would it cover me completely?

I really need to get this done. Speedy and complete answers would be very much appreciated.

Thanks!

most new router have the main connection and then a Guest connection, both these are separate and you have some extra control over the guest connection.  setup the router for yourself then enable the guest connection for everyone else that uses it.  your connection will have priority if bandwidth is being used by the guest connection.

Ty!

Does this mean that even if someone connects to the shared router via cable, the guest option is still enabled? Not just wifi?

Your confusing the point......there are 2 principle ways to connect to an access point/gateway, either through the air (wifi), or through a cable (ethernet).

 

Either doesnt matter......if your all connected to the same AP, your all on the same network, and can communicate with each other (for good or evil).

 

As suggested above, most modern routers (AP's) have the ability to provide a guest network (subnet) for which guests can connect to and share your internet access.

Remember, they are on a subnetwork, seperate from your principle network, so they cant interfere with anything connected to principle, or access directories on it.
