Sharing an Internet connection over a Wi-Fi Network

Once you've got your wireless network set up, I've no doubt that one of the first things you'll want to do with it is share an Internet association -- after all, that's why most home users put in a wireless network to begin with. Well, the good news is that Windows has Internet association Sharing built in. The bad news is that setting it up can sometimes be a limited less than fun.

The problem is that the Internet association Sharing Wizards that come with Windows 98 Second Edition and Windows Me don't work very well, and in some cases, can break your existing Internet Connection. The good news is that it's not that hard to set up, as long as you do it properly.

How Internet association Sharing Works

When you set up Internet association Sharing, you set up one of your computers as a 'gateway' to the Internet, and then use this gateway to entrance the Internet with your other computers. Essentially, requests for data from the Internet are being sent out straight through the gateway, and the responses are being sent back over the network ('routed') back to your computer. The gateway computer is still the only one that's directly related to the Internet.

If you have problem visualising what's happening, imagine for a second that the computers are people. Let's call the computer-people Bob, Fred and Alice. They're all in a bar together, but Bob is the only one with money for drinks (we could say he has a 'connection' to the bar). Fred and Alice can ask Bob to buy them a drink, and Bob can bring over the drinks, for them to have as they usually would. At no point, however, can Fred or Alice go and order a drink at the bar.

Setting It Up: The Gateway

Note: this guide assumes that you have already set up your wireless network, but you have not related it to the Internet yet.

The computer with the modem related to it is the one you need to set up first -- as the gateway, it's going to be providing Internet entrance to all your other computers. On this computer, go to the operate Panel, then click Network Connections. From here, you can run the Network Setup Wizard by clicking 'Set up a home or small office network'.

Click next straight through the wizard until you get to a screen called 'Select a association method'. On this screen you need to settle on 'This computer connects directly to the Internet. The other computers on my network associate to the Internet straight through this computer'. From here on, you should be able to click next again until you get to the finish. Say 'yes' to turn on file and printer sharing when you're prompted.

Your computer is now ready to be a gateway to the Internet.

The Network

The next step is setting up the other computers on your network to make use of the gateway you just created. Run the Network Setup Wizard on each of these computers, but this time straight through pick 'This computer connects to the Internet straight through another computer on my network or straight through a residential gateway'.

If the computer that will now be using a shared Internet association was using a dial-up association before, then there are a few things left to do -- you need to convert some settings in the web browser Open Internet Explorer, then go to the Options screen (in the Tools menu). Click the Connections tab. You should click 'never dial a connection', and untick three boxes: 'automatically detect settings', 'use self-acting configuration script' and 'use a proxy server'.

The problem With Internet association Sharing

To go back to our bar for a moment, imagine Bob leaves. Oh dear. Looks like Fred and Alice can't get any more drinks, doesn't it? The same thing applies to the computers on your network -- if the gateway computer is switched off, they will lose all their entrance to the Internet.

That's not the only problem, though. While Internet association Sharing works fine for the web and email, it can be more problematic when it comes to doing other things. Downloading files from filesharing networks, for example, or using videoconferencing, requires you to mess around with the gateway computer's settings. After a while, it can get quite frustrating. If you're in this position, you should nothing else but try a wireless router -- see our narrative 'Create Always-On Networks with a Wireless Router'.

Office safety - 10 Great Tips For a More derive Workplace

Today, businesses must address and get ready for security threats that are larger and more discrete than ever before. With each technological advancement that allows innovative, efficient firm strategies, comes a security threat that is equally innovative and equally effective.

Any appraisal of an office security theory should begin with exact security needs and the impacts they will have on your firm as a whole. You may need a installation derive sufficient for Ul 2050 certification or you may naturally need to ensure your employees security before and after firm hours. Regardless, here are ten leading ways to improve your office security system.

• Effective Communication: First and leading is communicating data to and in the middle of employees. Many associates use email alerts to warn employees about would-be hackers. Likewise, be sure that employees remain updated on procedures and possible visitors. By letting employees know what and who to expect, they are great qualified to recognize suspicious activities or persons. In order to avoid complacency, try to use a single source of data that becomes part of an employee's routine. This could be a daily server broadcast or informational email. Anyone the source, it should be brief, practical, and comprise sure news as well as precautionary information.
• Key Control: Assign the responsibility of locking or unlocking the office to as few individuals as possible. Eliminating the "first in, last out" formula ensures that all access points are secured regularly. Generate a procedure for those responsible for opening or closing your office that includes checking washrooms, closets, or everywhere someone might be able to hide. Hard keys should be numbered and assigned to exact individuals. Employees assigned keys should periodically be asked to produce their keys to verify a scholar registry.
• Site-Wide Policies: Something as easy as a "clean-desk" policy, training all employees to clear and derive their desks of necessary equipment or data before leaving for the day, drastically reduces possible theft. Mandating employees to have and display Id badges or access cards at all times increases the visibility of any unauthorized persons. Don't comprise job titles on any directory accessible to the normal collective as many criminals will use a name and title to justify their proximity in restricted areas. Finally, make sure to utter a "chain of possession." Any deliveries should be handed to a someone and not left in a hallway or on an unattended desk.
• Small Investments: All computers, laptops especially, should be secured with cable or plate locks to avoid "walk-off." Docking stations are relatively uncostly ways to protect electronic devices when not in use. Pay close attentiveness to high-risk targets like state-of-the-art equipment, postage meters, check writers, and firm checkbooks. improve doors by installing peepholes and keypads. Use two locked doors surrounding a small lobby or foyer. This type of "airlock" theory eliminates piggybacking, a formula criminals use to gain entry by catching a locked door as an worker exits.
• Anti-Virus: While it is highly unusual for a firm not to have anti-virus software in this day and age, it is impossible to overstate its importance. High-end security from viruses, spyware, malware, Trojans, and worms is one of the shrewdest investments an office can make. This includes firewall security for your main system, security for your wireless Internet routers, and securing backups of all data, preferably off-site, for recovery in the event of a cyber attack.
• Lights, Camera, Layout: Be aware of "dark spots" both inside and outside your office. Setup sufficient lighting in parking lots and outdoor break areas for worker safety, eliminate blind areas in stairwells, and dispose hallways and offices to take off any places where someone could conceal himself or stolen items. Short of Cctv, discussed below, it may be worthwhile to Setup recording security cameras at key areas like loading bays and access points like after-hours entrances.
• Reception: Among the more perfect solutions is to hire one or more full time receptionists. From a security theory standpoint, this someone allows for close inspection of credentials and identification and funnels security data straight through a single point. If it is impractical to have each visitor greeted and checked-in by a person, reconsider a dedicated phone line in your lobby or at your front door that goes only to a designated receiver. This method, combined with a sign-in station, can be a cost efficient strategy for many offices.
• Access operate System: One of the difficulties with hard keys is reacting when one is lost or stolen. With an access operate system, businesses can issue access cards to employees while maintaining perfect operate over what each card will open. Moreover, access operate systems minimize risk by allowing only sufficient access to perfect a job. Thus, employees, contractors, or visitors can be restricted by area or time of day. Two things are necessary with access operate systems. First, allow "total access" to as few individuals as possible. This will justify who is authorized to be where and thereby enable employees to recognize and article infractions. Second, monitor the use of each card. By reviewing card activity, you can decide who needs access to where and at which times, streamlining routines and defining access.
• Closed Circuit Television (Cctv): For higher end security theory needs, Cctv is one of the most efficient methods of protection. straight through minute broadcast, each camera can be monitored straight through a single interface. Depending on the specifics of the system, footage can be monitored by an worker or digitally recorded. Place cameras strategically to achieve the maximum coverage for a single unit. Likewise, cameras or corresponding signs that are graphic to guests and employees can be efficient deterrents and Generate a safe environment. It is leading to remember, however, that as efficient as Cctv is, it should be used efficiently and in tandem with other measures. For example, installing a unit in an entry with an "airlock" door theory allows extended footage of a person(s) entering or exiting the premises.
• Proper Training: Above all, make sure each of your employees is adequately trained to use security equipment and follow procedures. Investment and planning in the best security theory will have minute impact if individuals are unclear on precaution and intervention. This may be as easy as development sure employees keep doors and windows derive or protect their personal belongings, but often entails exact training on identifying and responding to suspicious items, persons, or events.
