Share Your Laptop Via WiFi 3G

Internet connections through mobile lines are increasingly popular 3G. No matter if it is business or leisure, this kind of access to the Internet starts to become popular and many times we wanted to share it with other people or teams that we have around.

In fact, they are becoming a good solution for those who make a moderate use of the Internet and prefer to pay some fee flat low cost, rather than hire a fixed line and pay an ADSL. In this environment, or in the case of nomadic working groups (Auditors), temporary mounts, mobile offices, it is useful to share that connection between multiple computers via WiFi 3 G for, thus, make it the most. Here, we show you how to do it from Windows Vista and Windows 7, or from an Apple Macbook with Mac OS X. In one case it is take advantage of the options of the operating system itself and, on the other, take advantage of a powerful free utility. Each, according to your system and preferences, may opt for the solution most suitable for it. That Yes, assume that we have previously fully operational 3 G through the USB modem or mobile connection.


Access to Internet sharing in Windows vista

Create a WiFi network
In Windows Vista we will take advantage of the features that offers us the operating system itself to carry out our objective. That Yes, its launch is sometimes heavier than expected. The first thing we need to do is to create an ad hoc network. To do this go to start / connect to / set up a connection or network / set up an ad hoc wireless network (of computer-to-computer). In the wizard that will begin, we will assign a name to our network, check the level of security (WPA2-Personal recommended), and indicate a password to the network. When finished, go to start/control/media Panel and Internet/network and sharing Center and click on the option to connect to a network. We will be shown a list of all wireless networks detected, where it should appear that just created with waiting indication to users to connect. That Yes, if we were connected to any WiFi, will have to disconnect us simply by double clicking on it.

Share the 3G connection
In the next step we will indicate which connection Internet access we want to share. To do this, go to network and sharing Center as in the previous step and click on the option manage network connections. Here, with our modem or 3G connected, will have to locate the connection of the same. Depending on the type, model and software may have the name of the operator or any other. Once located, we’ll click with the right button of the mouse on the connection and click on properties. In the window that opens, we will have to go to the sharing tab. Here, we will mark all checkboxes, indicating in the drop-down which connection is that we want that you can access the shared Internet connection. In our case, we’ll mark the option wireless network connection. Finally, we landed to the Setup button to indicate what access to Internet services will share, marking at least Service Web (HTTP) so they can surf, and Internet Mail Server (SMTP) and post Office Protocol Version 3 (POP3) if they will need to handle POP3/SMTP mail through the shared connection.

Transfers from other PCs
Once done, we recommend to restart Windows so that it correctly loads the changes and to return to start, check (as shown in step 1) that our network ad hoc we have created is waiting for connections. Then, we don’t have rather than go to another portable (be Windows, Linux or Mac) or any WiFi device you need to access the Internet and search through the available wireless networks computer network name team that we created in step 1. To connect us to it, automatically, the computer that acts as an access server assigns us an IP through DHCP and connection is available to start navigating.

Sitecom WL326
Routers with optional 3G connection have been long in the market, however, so far tended to be high mid-range models which, by its low sales volume and increased need for technology, were really prices against conventional routers. Luckily, a few weeks ago Sitecom presented his WL-326, a small router with two LAN ports and one WAN, in addition to acting as a router WiFi 802. 11n (up to 300 Mbps thanks to the two antennas integrated in the casing), also has a USB port. It can connect a modem 3G Huawei E220 or E270, two of the most popular models of the Chinese manufacturer, with the rate our operator flat. Its use ranges from sharing a connection of mobile Internet in our holiday house or in working groups moved out of the office, to act as a backup connection when WAN port connection (ADSL modem or cable) fall. Its price, € 79.99.

Access to Internet sharing in Windows 7
Exclusively for Windows 7, we find a utility that allows you to do the same as above but in a much more simple and fast way. Its installation is completely automated, so you only have to go clicking Next until the end of the wizard. Once installed, we will have new shortcuts in the start menu and a new icon in the form of radio waves in our taskbar, next to the clock. Prior to setting up Connect, connect your USB/mobile phone and will link it to the Internet to have an active connection. This detail is important, because when you start Connect, analyze connections available to share, and if one is not when you do so, we do not share it. That is why, if we had the icon loaded on the taskbar after you connect to the Internet with modem / 3G mobile, do click on it with the right button of the mouse and click on Exit. We will close the application and we will load it from start / all the programs/Connect, after that we’ll see again the icon on the taskbar.

He begins to share
Now, you only have to click on the mentioned icon in the form of radio waves that will be released next to the clock. The window of Connectify, where we will start by assign a name to the network which we are going to create, and indicate a password in hexadecimal format. That is, only with letters from a to the f2, and numbers from 0 to 9. Finally, in the Internet box, select in the drop-down connection to access 3G that we wish to share (hence the importance that it is activated). Finally, we’ll click on the Start Hot-spot button at the bottom. In a few seconds, we see how at the top tells us Running. As a curiosity, where No AP Mode Supported error message appears, do not you should worry, because we will not affect to the present practical. Connect allows only with certain compatible WiFi card, establish an Internet connection shared on the same WiFi that can access the Internet, although given that it is not our goal, you will not have greater importance. Finally, as in step 3 of Windows Vista, you only have to go to each remaining, look for the created network and enter the password indicated laptops or wireless devices. Thus we have automatic IP and connection to the Internet immediately.

MiFi, elegant solution
Already we have speaking on other occasions of the MiFi, access points, Mobile Pocket that the Novatel company launched almost a year ago, although Huawei also offers its own version of the product in some markets. The MiFi are small access points 3 G/HSDPA integrated WiFi, DHCP server to assign addresses automatically and a small battery that gives them limited autonomy, ideal for when we have no possibility to have a plug nearby. The potential of the MiFi is twofold. On the one hand, it allows to connect via WiFi up to 5 computers to a same connection 3 G quickly and easily, as we would any WiFi router from home or the office. On the other hand, allows us to take advantage of a 3G device connection that until now it was not possible or easy to ‘mobilize’: from portable consoles, to PDAs, digital cameras with WiFi, photo frames or music players (like the iPod Touch). In Spain, MoviStar and Vodafone offer a couple of Novatel models, both associated with flat rates and prices that start from around €29. On eBay and other stores online can find completely free new models from about €180.

Access to the network shared on Mac

Meet the adapter
In Mac OS X operation share our connection to Internet via WiFi is even easier than with Windows. The first thing we have to do is go to system preferences (by clicking on the Apple at the top) and click on the network icon. What you will see below is a listing of the connections of the system. If we connect our modem and link it with the Internet using the included software, we will see how the device appears in the list, having no more than staying with his name. The case that we use an iPhone directly connected via cable to take advantage of Tethering function, will be shown a new device called iPhone USB. Once we have clear the name of our …
