2 networks, 1 house

post #1 of 12
Thread Starter 
Hello network experts biggrin.gif i have a question and value any input you have to offer!

background: Im going to school for computer science and i think maybe i might wanna do something in info sec, plus i think this kinda stuff is cool. i love learning everything about computers and i know a little about everything but now im trying to learn alot about everything smile.gif

so basically my question is i have the ability to get another modem and a wireless router and put it in my room in addition to the network my parents have set up in the house and im thinking i may want too. I figured it would benefit me in the following ways;
-i could learn to secure my network, you know just the basic stuff, and mess around in my own network.
-also there are probably 9 or so devices on in my home network at a given time; my pc, my macbook, moms laptop, dad's ipad, xbox (sometimes for netflix) brothers laptop. u get the gist. and more times than not i experience some lag. not really sure that this would be causing the lag having all of these devices running but im uneducated in this area and want to learn anyways smile.gif
-Sometimes even my gf will bring her computer over and that adds to the load.
(see i dont know if maybe its the router thats is bad, i wouldnt think so tho because its a pretty new netgear one, white, probably had it for a year or so)
-also, not that big of a point but i figure i may as well get one considering i may be out on my own in te next few years so i would already have a router and stuff out of the way as someting to buy!

im really interested in the area and the thoght of having my own network private to myself and my devices and as a learning experience so i would love to hear back from anybody and please keep the harsh remarks to yourself tongue.gif
Also just if there would be any benifits at all, because im not sire that if i then too have my own network if it would just slow down the house as a whole, beats nme im new biggrin.gif
And one last fact we have cox, just incase any of u ask, so its not like we have poopy cable or internet!


Thank you so so much and i cant wait to hear back biggrin.gif

It would still only be one network.... but with sub-nets.


You can play with virtual networks which would be more interesting and have less effect on others.

okay... well i didnt know, like i said im new at this.
So there would be no gain at all, performance wise?

and how would i go about playing with a virtual network?

Couple things:

1) If you are experiencing lag, I would say that either your download speed is not very fast, or that multiple people are downloading large files or streaming. You shouldnt have any issues with a bunch of web surfing clients.

2) You can set up your own router in your room, but you would need an additional ISP line coming to your house to be completely off your parents internet. This would cost more money, and honestly, I am not sure an ISP is going to connect a 2nd line for cheap, if at all. If you wanted to only affect your router by making changes, you could likely connect the 2 routers with a LAN cable and create a seperate SSID for your router and only connect to that, but in the end, you would still be passing through theirs and out the same network you are today.

If you are interested in learning networking commands and security, I would suggest checking out Cisco books on the different topics you may be interested in. CENT and CCNA would be a good starting point to teach you about networks and subnets, and you could go on from there.

If all of those devices are competing for WAN bandwidth, yes I think to experience a bit of lag would be normal. As far as localized bandwidth latency, it would take a bit more to generate noticable latency.

Some folks run two internet services (one for general use and another for dedicated hosting of some type of service) so that might be something worth looking into as well.

Some will - Wide Open West and Time Warner will allow for multi-service configurations.

Okay cool thanks for the input guys smile.gif good thing I checked here before going ahead and buying something and wasting my money hahah! I guess I will check into the Cisco type books but do those teach security aspect of it of is it jut like setting them up and stuff!? I want to know more about what that one guy said though sounds intriguing! What's a virtual network? Kinda like a practice ground or something?

Set up virtual machines and a virtual router that exist only on your PC.

I believe he is referring to VLANs, which are covered in CCNA books. I don't know if any home routers do it, nor do I think it would be necessary, but its a way of taking a single switch, and making different ports on the same switch part of different networks. If you have 200 computers on a single subnet, for instance, they all hear broadcasts from any other computer on the network. By dividing the subnet in half, each subnet receives half of the broadcasts, making less traffic on each network.

Ah, something completely different smile.gif

A start might be the CompTIA Network+ which might help you get into the networking field.
Another part is the Cisco Series of Exams which goes pretty far.

Personally get maybe a Linksys WRT54G as it's one of those Routers that supports all of the Custom Firmwares. (Which all have different uses).
You can also get into learning Cisco CLI via a Stack of Cisco Routers, and Switches.
