You can get a gigabit Ethernet switch and connect it to one of the LAN ports on your router and expand your network. A decent 8 port gigabit switch is fairly inexpensive, usually $20-40 USD or so (probably more expensive in NZ). Note that one of the 8 ports on the switch and one of the 4 LAN ports on the router would be used, so that would leave 10 LAN ports for computers.

you can connect more routers to your router. they're more expensive than switches but also faster.

would that be a good switch?

How would you do that? As far as I can see routers are dsl in ethernet out. Mine only has one dsl in slot. I think I have a router lying around but I dont know how I would set that up.

That appears to be a 10/100 megabit switch and not a 1000 megabit (aka gigabit) switch, but it'll work. A gigabit switch would be preferred especially if your router has gigabit LAN ports, simply for 10x more bandwidth if you are doing any inter-network file transfers, but for a small LAN party it should be okay.

TP Link are good cheap ones, go for it.

get a linksys, cisco, or netgear switch, they all make good shit. figure out how many people will be attending and then buy one with as many ports as you'll need: http://www.newegg.com/Switches/SubCategory/ID-30

switches replicate every package they receive to every connected terminal, it's up to the terminal (the pc) to figure out what packages he should read and what packages he should discard, this adds up latency.

routers creates a network with every connected device and manages different local IPs for each one of them which allows them to redirect every package to the right terminal.

I've also tried them both, bought a switch then bought a router and router turned out to be faster.

don't 1v1 me lange, we have the same major

you connect an ethernet cable between both routers and then setup the router without dsl connection to know that it can find the internets through the other router.

This isn't true. An Ethernet hub is an OSI layer 1 device that broadcasts all signals received on a port to every other port excluding the port where the incoming signal originated. Since they operate at the physical layer, hubs cannot discern what a frame is. The entire hub is a single collision domain and every device must take turns transmitting or receiving signals.

An Ethernet switch is an OSI layer 2 device that is capable of analyzing frames because it operates in the data link layer. Therefore, it is able to analyze frames and forward them to the appropriate port. This is why switches don't have collision problems, because each individual port becomes its own collision domain.

A router is a layer 3 device with makes it superior to hubs and switches, but having more than a single router on your network is utterly pointless because it will manage every device on its LAN anyway.

"A switch is a telecommunication device that receives a message from any device connected to it and then transmits the message only to the device for which the message was meant. This makes the switch a more intelligent device than a hub (which receives a message and then transmits it to all the other devices on its network)."

Oh man, Run Kitty Run on dial-up internet. Those were the days.

shit there was this super fun warcraft mod where you played as wizards who fought on an island slinging spells at each other
i don't remember the name of this but it was SO fun

chill and buy a switch. not recommended for the laptops to use the wireless.
