How do I turn these five connections off? Ethernet jacks on campus are set up to automatically shut off once they detect network bridging. Plugging your computer into another jack will disable that jack as well. Note: Some computers and network adapters may use network management software other than the built-in applications included with an operating system especially on Windows.
If you find that this is the case, the process described below will be similar, but the steps may not apply exactly. Consult the Help documentation for your network management software or contact the IT Help Center if you need assistance. Please do not use more than one network connection at one time. Windows 7 On the Windows taskbar bottom, right , right-click the connection icon and select Disconnect from [connection name].
Windows Vista On the Windows taskbar bottom, right , right-click the connection icon and select Disconnect from [connection name]. Mac OS This will keep your operating system from using the disabled connection until you re-enable it.
To enable your connection, reverse the process you followed below. Consult the Help documentation of your operating system if you need assistance. You can get there when you first power up the computer, or by restarting Windows and waiting for the screen to go black. The screen tells you what key to press; it's usually the Del or F2 key. Find an entry titled AC Power Recovery, or something similar. Change the setting so that your computer turns itself on when the AC power comes on.
On some computers, there is also an option that turns on the computer only if it was on when the power failed. That works, too. Automatic startup is generally not an option with a laptop computer. If you want remote access to your laptop, you just have to leave it on and hope that the battery takes it through any brief power outages.
Besides a 24x7 computer, you need a 24x7 Internet connection. If you have cable Internet service or a type of DSL service that does not require you to enter a username or password, you have an always-on Internet connection already and can skip ahead to the next section. For DSL service that requires sign-on, you need some means of automatically reestablishing the connection whenever your computer starts up or the connection goes down.
Microsoft's built-in Broadband connection sign-on software does not provide a reliable way by itself to keep the Internet connection permanently open. You can work around this in three ways:. You can use a hardware connection-sharing router.
The router connects to your DSL modem and your computer s to the router. The router makes the DSL connection for you, and you can configure it to keep it going all the time. If you don't have a router already, it's a worthwhile investment to buy one. Be sure to enable the router's "keepalive" feature so that your connection is kept going all the time. Otherwise, the connection might be allowed to close when there is no activity from inside your LAN, and you might not be able to connect later.
All Internet connections are established on the basis of a number called an IP address, which is to your Internet connection as your telephone number is to your phone. Your IP address uniquely identifies your computer among all the millions of connected computers worldwide. If you use a shared connection, all your network's computers share one public IP address, much as the phone extensions in an office share one outside telephone number.
The question is, when you're somewhere else, how do you find your computer's IP address so that Remote Desktop can establish a connection to it? It has four sets of numbers separated by periods and looks something like this: This will always be your computer's number.
You can simply type this in when using the Remote Desktop client to connect to your computer. However, static addresses are relatively hard to get and usually carry a monthly surcharge; in some cases, ISPs simply cannot or will not provide them.
So although this is worth looking into, it might not be an option. My home ISP is sonic. In most cases, dial-up, DSL, and cable Internet connections use dynamic addressing, in which a different IP address is assigned to you every time you or your router connects to your ISP or, in the case of cable service, whenever your cable modem is reset.
Thus, your computer's IP address can change at any time, and you won't necessarily know what it is when you want to connect from somewhere else. The solution to this problem is to use a free dynamic domain name service DDNS. It has two parts: First, on a DDNS provider's website, you register a host name , a name of your own choice, attached to one of several domain names that the provider makes available.
For example, you might register the host name mycomputer in the domain homedns. Some Internet connection-sharing routers have a DDNS client built in, or you can download and install a software version on your computer.
When this is all set up, you can use the name mycomputer. Many DDNS providers exist, most of which are free services. Here I give you step-by-step instructions for setting up service with dyndns. Now your DDNS service is set up. Your router's setup screen will likely differ from this, but it will generally look something like the one in Figure Figure Type the command ipconfig and press Enter.
Note the gateway address for the local area connection entry, which will be something like Close this window and open Internet Explorer. If your router doesn't have a DDNS client built in, or if you are not using a hardware router, you have to install a software DDNS client to do the job.
You want one that doesn't require any manual intervention to get started and that always runs even when nobody is logged on. This means that you need one that operates as a Windows service rather than as a regular desktop application. Here's how to set it up. If you use Windows Internet Connection Sharing, perform this procedure on the computer that shares its connection with the Internet, whether or not it's the computer that you're enabling for Remote Desktop access.
Otherwise, do this on the computer that you're enabling for Remote Desktop access. Follow the wizard's instructions, clicking Next after you fill in any required information on each page.
On the first page, if you have dial-up or DSL service that requires a logon and password and the connection is made directly from your computer , click Dial-Up. If you have cable Internet service or you have a router that establishes the connection for you, select Local Area Network. Now your registered host name will always point to your computer, even when your IP address changes. After a change, it might take up to an hour for the update to occur, but changes should be infrequent.
The last setup step is to make sure that incoming Remote Desktop connections from the Internet make it to the right computer. If your computer connects directly to your cable or DSL modem, you can skip this step. However, if you use Internet Connection Sharing or a connection-sharing router, you have to instruct your sharing computer or router to forward Remote Desktop data through to your computer.
