New home to network!

post #1 of 12
Thread Starter 
My family has built a new home with networking installed. The only problem is that i have a DSL modem whish has a built in router. The modem can only support up to 4 other computers which won't work because I have 8 ports in the house. I was wondering if this switch would work. Could I plug in my modem/router in to this and get internet out to every port? Is this possible with a switch or do I have to use a router?

The switch should work great.

The router allows multiple computers to use the same internet IP, so you only need one router. A switch just adds ports. If you plug the switch into any port in the router, every port in both the router AND switch will be able to see eachother... including access to the internet. So just get a small switch, plug it into the router, and you will be just fine.

To be consistent, I would put one connection from the router to the switch, and then all the internal connections to the switch.. so kinda like this:

Modem Port WAN (Out to DLS)
Modem Port 1 - To Switch Port 1
Switch Ports 2-8 .. anything you want.

For me it seems less messy but you can do it how you want.. unless you have FiOS or something you won't be running 100mbps downloads from the WAN connection.. so this setup is kinda perfect

Switch is a layer 3 device. A router is a layer 2. So, yes, your config would work. The only thing I see is that the switch is a gigabit switch, and your back end devices (nic cards) would need gigabit cards. Other than that, would work fine and price is good too.

Is that so? I thought the switch would step-down to the slowest device.

Where is the rule of Your chain is only as strong as your weakest link? (or something like that)

From Cisco's website:

"LAN switches can be categorized according to the OSI layer at which they filter and forward, or switch, frames. These categories are: Layer 2, Layer 2 with Layer 3 features, or multilayer.

A Layer 2 LAN switch is operationally similar to a multiport bridge but has a much higher capacity and supports many new features, such as full-duplex operation. A Layer 2 LAN switch performs switching and filtering based on the OSI data link layer (Layer 2) MAC address. As with bridges, it is completely transparent to network protocols and user applications.

A Layer 2 LAN switch with Layer 3 features can make switching decisions based on more information than just the Layer 2 MAC address. Such a switch might incorporate some Layer 3 traffic-control features, such as broadcast and multicast traffic management, security through access lists, and IP fragmentation.

A multilayer switch makes switching and filtering decisions based on OSI data link layer (Layer 2) and OSI network layer (Layer 3) addresses. This type of switch dynamically decides whether to switch (Layer 2) or route (Layer 3) incoming traffic. A multilayer LAN switch switches within a workgroup and routes between different workgroups.

Layer 3 switching allows data flows to bypass routers. The first frame passes through the router as normal to ensure that all security policies are observed. The switches watch the way that the router treats the frame and then replicate the process for subsequent frames. For example, if a series of FTP frames flows from a 10.0.0.1 to 192.168.1.1, the frames normally pass through a router. Multilayer switching observes how the router changes the Layer 2 and Layer 3 headers and imitates the router for the rest of the frames. This reduces the load on the router and the latency through the network. "

I just set one of these up at a remote location. The gentlemen told me to purchase a switch. I purchased a Cisco switch and went in only to find no router. I had to bring up technical jargon to make him understand the scenario, lol.

I'm not networking fluent

The last line of the quote I understood. Even if it did reduce the load on the router, the network can only transmit data as fast as the slowest device (router or otherwise) unless it bypassed the device (I think thats in there somewhere also).

So in other words... that I can understand right now

If it goes through the PC > Switch > Router > Net then it is as slow as the slowest device.

But If The PCs had gigabit cards, then PC > Switch > PC would be as fast as the gigabit cards or the speed of the switch?

Sorry if this is potential hijacking your thread

Switches work great...
They normally are sold in 4,8,16,32...
So you should be able to get an 8 port Switch for really cheap...

From your modem's LAN/Internet Port, connect that to WAN port on switch, and use all the LAN ports on the switch...

It's better to not use any of your Modem's LAN ports IMO, just the one that goes to the switch...

Now with my problem??? I think my new wireless router is broken
