I know michaelmurfy has already covered routers recently, but I need a straight yes or no answer.  Please excuse the simple/broad terms I may use.

 

Here we go:

 

Can a network switch, be used like a normal WiFi router, for just Ethernet, to provide Internet connection to my PC?  Secondly, do they all support VLAN Tagging and stuff for Fibre (e.g. will the cheapest one from PB Tech work)?

 

 

 

I know I'm using simpleton language, and that this may seem like a stupid question; but please, I need to know.  Once this has been answered, there need not be any other replies; unless the answer was wrong there is more important information to know about it.

Simple answer: No.

 

A switch is not a router.

 

A "Layer 3 Managed Switch" is sort of, kind of, like a router, but usually won't do things like NAT, DHCP, DNS Caching as needed for an Internet connection, just very basic routing between VLANs.

 

Cheap switches are not managed, won't do VLAN tagging, etc.

An overly simple explanation is that a switch just connects all the wires together but doesn't have any "logic" in it. It therefore can't handle VLAN tagging etc.

Thanks for that. Just one more question then, what switches, if any, will let me connect to the Internet (preferably from PB Tech), and how you tell if they will?

None.  You need a router.

Well then. That settles that. Could you point be in the direction of the cheapest router that has only Ethernet (if one with WiFi is cheaper I'll still take that). All I need is for my PC to always have Internet, it doesn't need to be fast, it just needs to work.

You need a router connected to your ont, with your pc somewhere behind that. Switches just allow lan devices to talk to each other and to the router, to get traffic to/from the internet you need to route it - hence router.

You've seen routers with ~4 lan ports before? Esentially those 4 ports are a switch built into the router - how you use those ports is how you'd use a switch if you had one.

You will want a router, not a switch.

Wait. Aren't you the guy who was asking about using an rPi as a router before?

You are on fibre just use the modem/router supplied by the isp.... if you need more Ethernet ports, buy a cheap GB switch and connect it to the modem router...it should have an Ethernet port for this but check.

Probably it would help if u told us your ISP and number of Ethernet ports you need too.

Not many cheap routers do vlan tagging, best get one of the ones supplied by your ISP - look on trademe for people that are offloading them because they have upgraded to an overpriced fancy looking router.

If you're just connecting a single PC to the internet, you don't need a router, or a switch. You can simply plug the PC directly into the ONT.

I use Spark.  And I need just one.  As Spark need VLAN Tagging and stuff to be able to connect to the Internet on Fibre, I can't just plug it into the ONT.

I don't know much about vlan tagging myself, but, are you sure you're PCs NIC doesn't support vlan tagging? I have a feeling newer intel NICs probably do. If you're looking for a cheap solution for just one PC and you have spare expansion slots in your PC, a new network might be an option, if your currect NIC doesn't support vlan.
