How to Connect Two Routers

Connecting two routers together lets you expand the number of ports in your network. It also lets you increase the range of your network. You can connect routers together using an Ethernet cable. The second router is plugged into one of the free local area network (LAN) ports on the first router. Follow the steps below to connect two routers together; the information works for both wired and wireless routers.

How to Connect two Computers using USB

Steps
    



1.Connect the second router to your modem. The modem should be connected to your computer. Make sure the router isn't connected to any other devices. You can leave your first router unplugged and disconnected for now.

 

  


2.Open your Internet browser and type "" http://192.168.1.1./" into the web address bar. This will bring up a router configuration page.



3.Alter the LAN IP address to an IP that is not the default "192.168.1.1" address.
  • You could use an address like "192.168.1.2" as long as it is not used by any other device. The addresses need to be different so the routers can communicate with each other correctly.  

 

4.Turn the Dynamic Host Configuration Protocol (DHCP) server off on the second router. Save the setting. DHCP is used to automatically configure IP addresses for the different devices on a network. The first router will issue a DHCP server address to the second router. Turning off DHCP on the second router prevents conflicting IPs.
    



5.Disconnect the second router from the modem.
    




6.Insert an Ethernet cable into an open LAN port on the first router and connect it to an open LAN port on the second router.
Do not connect the cable to the Internet/WAN (wide area network) port of the second router.

Tips

  • If you obtain a long Ethernet cable to run between each router, you can physically extend the range of your network. This works for both wired and wireless routers. Extending the range of your network will allow you to have devices placed further apart from each other, such as in a house or office.

Warnings

  • If your second router is connected with the Internet/WAN port, extra steps must be taken to achieve correct port forwarding. The first router must be forwarded to the second and the second must be forwarded to the computer.
  • If you are using two wireless routers, the second router Internet/WAN setup will cause wireless devices to communicate improperly. If a wireless device gets too far out of the range of the first router it will be assigned to the second router and need a new IP address to work.
  • Connecting an Ethernet cable from a LAN port on the first router to the Internet/WAN port on the second router can cause a number of communication problems. Computers or devices connected to the second router will be able to connect with computers connected to the first, but computers on the first router will not be able to connect with computers on the second.

How to Hack Into a School Computer

To gain access 
to ("hack into") administrator privileges on a school computer, 
just follow the 
steps below. These activities are not condoned by this article.


Method 1 of 5: Accessing the Command Prompt


1.The Trophy. The goal here is that it doesn't work to gain access to an administrator account. Doing anything malicious or damaging is illegal and unethical, so please don't! The ethical thing to do would be to find a way into the system through cunning and intelligence, and only make it obvious that the system has been compromised.
    
If you can access cmd.exe, then change the password of an Admin, and change their personal settings, and be awesome to change the wallpaper to something humorous (if you can't, open Notepad and type in the following to get a something like a copy of it:

        @echo off
        cmd
        echo on

    or type in "start command.com" Save as a batch (.bat) file and change "Save File as Type" to all       files; do not save as txt.


2. Scope out the battlefield. See if the command prompt or the registry is enabled on student accounts. With these enabled, you'll have quite a bit of power.


3. USB stick beside the teacher's computer in the computer-room/library/classroom, with an autoexec file that compromises the account in some way, similarly you can doctor a USB mouse to contain a USB drive with a similar autoexec file. Write a program that looks like the login screen, or some login screen that your Admin might use, and ask him to enter their password. The possibilities are endless.
  • Social Engineering can be really handy, the more you know about someone, the better it is. Just get to know every little detail about them, personal details (telephone number/email-address etc), hobbies, likes/dislikes; just everything! And you will be able to guess the password eventually, or get the person to say theirs because they trust you enough;bingo!

Method 2 of 5: Obtaining Passwords


  • If you want to crack the Administrator account using software, follow these steps. It might be easy, but it isn't fun.
  • Download pwdump to the computer that you are using. If the site is blocked then you should download it to a thumb drive and put it in the computer.
  • Right click in a any folder and then New>Text Document.
  • Open it and type "command.com"
  • File>Save As and save is as something.bat.
  • Double click on something.bat.
  • Navigate to the pwdump folder using CD the location of pwdump.
  • Type "pwdump.exe -o hashes.txt localhost" (without quotes) and email hashes.txt to          yourself or put it on your thumbdrive.
  • On your own computer Google-install ophcrack and follow one of the guides.
  • Click load pwdump file and locate the text file to load the hashes.
  • And you cracked the administrator.

 

Method 3 of 5: Using a LiveCD


  • If you are unable to get the admin password with windows ophcrack then try these steps.
  • Download the ophcrack live CD iso.
  • Burn it to a CD.
  • Place it in the computer you want to hack and set up the computer to boot from CD. You can set     this up in the bios set up.
  • Boot from CD in graphical mode and ophcrack will attempt to crack the passwords automatically.

Note: if the CD is unable to find the password, this is because the admin password contains a special character. This means that to crack it you must first download the rainbow tables named xp special or vista special. The only way I know how to do this is through a torrent. Then you must put thm on an eternal hard drive and use them with the live cd.
    • Enjoy the password but DO NOT do anything against your school's wishes with it.

     

    Method 4 of 5: Creating an Administrator Account 


    • Open Run and enter {cmd} then open it. Once you open it, type {net user /add } and type a username, put a space and type your easy-to-remember password. Enter it into the prompt and log off. Now you can log onto that file without anyone knowing that you are now an administrator. 
         1.Have fun with your restrictionless account! It's literally restrictionless because you're an    admin!

    Method 5 of 5: Changing Mac Permissions


    1.Another method which does not grant you server access is to make your self an admin. However this may mean you can modify permissions on anything. Please be careful with this - you could stop the computer from accessing the school network, or you could corrupt the operating system.

    2.This works on Macs only. Don't bother trying this on a PC.
    • Boot the computer into single user mode (hold command + s while booting)
    • Let it scroll through the lines of text
    • Type
            sbin/mount -wu
            sbin/SystemStarter OR launchctl load /System/Library/LaunchDaemons/com.

        apple.DirectoryServices.plist (this is faster)
        passwd root
    • Now type what ever password you want/ can remember and hit enter.
    •  Type
            reboot
    • It will auto reboot the system when you get to the login screen use root as the login and your new password and viola.

     

     Tips


    • Unblock a games website, it won't do any harm, and you'll get some respect!
    • Take any possible opportunity to make a laugh out of the school's IT staff, they deserve it if you've compromised the system.
    • If you can't access cmd (command prompt), make a shortcut at home and bring it on a USB pen drive or something. It will work this way.
    • Never delete things or use private data maliciously, or alter files. Gaining access in the first place should be your goal, not causing damage.
    • In some British counties in state-run schools, you may not be able to unblock sites as this site blocking may be managed by the county, as opposed to the school. It's still worth a try though as it may work but it may not though!

     Warnings


    • Don't tell the class attention-seeker. They're likely to tell authorities what you're up to.
    • Always ask yourself if what you are doing is justifiable under the gaze of the principal.
    • Make sure when doing this to sit somewhere that there are no people. If they see you it is most likely they would tell authorities.
    • Don't do anything malicious or damaging in any way.
