Links and Networking

A network runs on three types of devices, the Router, the Switch and the Hub. I give a basic description of each and comment on when they are used.

i am new to networks
hi i am BE grad 07 passed out. completed course in sap – abap in a local institute but no jobs till now. please kindly help me wheather i switch to networking course as ccna. New to this pls help me about job in ccna???? thanks arvind

I am not sure what you are asking but the CCNA is a great starting point for those interested in networking. Eventually you want to get a CCIE, but the CCNA is good just about anywhere for a starting position.

I am a college student and my room has only one internet source. I have a wired router that gives my 4 cat5 ports. The problem is this creates a network of its own. I need to be able to communicate to other devices on the network, I know turning it into a network switch will solve my problem. But my problem is that I cant seem to figure this out, please help me out here.

Most routers have just such a function. The first thing to try would be opening your internet browser and enter in the gateway IP address (the router’s IP address) into the address bar. Almost all routers these days have an open interface that will allow you to specify or change the settings. Somewhere listed in the settings should be a "mode" you can change between "router", "bridge", or another function it may be enabled for.

I am going on vacation with the family. We are family of addicted avid games and would like to spend one of our 14 days cooked up in our hotel room having a lan party. I have a linksys router at home and a switch as well. Could I just bring the switch or do I need the router intstead. I am not looking to go online.. just a closed LAN.

lol, we used to use just an 8 port hub to do it.
After that we moved on to switches until routers became cheaper and started having more ports.
Now everyone uses routers but yes, you can use a switch.

Hi, I recently bought a Dynex 4-Port 10/100 Ethernet hub. I want to connect my cable modem (motorola surfboard), My Desktop, and My Linksys Wireless g Router. How can I set this all up. It tells me that there is an uplink port. What do i do with that? Please help, parents are taking me to the store today to return it and i want to at least see if i didnt waste my money.

Your cable modem will need to be connected to your Linksys router. This is because the router will serve as the device that has your location’s IP address. The IP address is your unique identifier on the internet and you can only get one per home. Using the router will allow you to use more than one computer in your home. Now there should already be four additional ports on the Linksys router- you need to plug your Desktop into one of those. This will allow you to have three more devices on your network and then some that have wireless capabilities. Now the only reason that you would need that Dynex device is if you have more than four devices that you need to plug in for internet access. If so, then the Dynex device needs to be plugged directly into one of the ports on the Linksys router coming from that uplink port.
I’m pretty sure you will not need that device- unless you have a lot of computers are you’re holding a LAN party

If I switch will I have to re-friend everyone in that network?

No. You don’t have to re-friend.

It will keep all your friends, regardless of which network they are in or which network you switch/are in.

You’ll notice that you and other have friends from different networks and it breaks down all the different networks your friends are from.

I have a modem connected to a router, the router connected to a switch and 4 computers coming out of this connection. I want to know if besides the router (which I more or less know how to configure) the switch needs something I need to know or if it’s simply there splitting the connection and needs only electrical power and that’s it.
I mean if I need to know something that I don’t. I just want to make sure that I do things right

Most consumers switches are plug and play. If you have a enterprise type switch, then you can console into it to setup vlans and other configurations. Even with a enterprise switch, they act just like any other switch out of the box. Consumer switches typically go up to 16 ports (maybe more if you have the money) while enterprise switches have 24 or more ports and have a serial or RJ45 console port.

This is always confusing to explain, but I will try my best to clarify: I have an Internet connection that is plugged into a router. There are two cables plugged into the router. Cable (A) connects directly into Computer (A). Cable (B) connects to a switch. The switch has two cables connected to it. Cable (1) connects to Computer (1) and cable (2) connects to computer (2).

The problem is that Computer (2) is not connecting to the internet. Computer (1) is fine and has no problems, but computer (2) displays "limited to no connectivity". I have tried the "repair connection" option, but does not work. Any help would be greatly appreciated.

Well few things to check. One try taking the cable from Computer 1 and plugging it into 2. Also can plug cable 2 into computer 1. If computer 1 still gets a connection and computer 2 does not, we know its not the cable.

Next up is check the TCP/IP settings. Can probably double click on the connection -> properties -> TCP/IP properties -> and it should say obtain an address automatically.

If it is already set to that then we need to check the router. You can try plugging only this computer directly into the router to see if the router gives it an IP. If this occurs then it could be a setting of max IPs given by the router. Though I doubt you changed it… should check anyways.

If it doesn’t give it an IP, then I’d say could potentially be a faulty driver or the NIC can be bad. I’ve had NIC that seemed to work, but were just dead. Have no idea why either.
