Find out why and how to work wirelessly, and a few safety precautions

Working wirelessly: What you need to know

Many companies are making the leap to wireless networks in the office for both financial savings in overall equipment and sheer convenience for their employees. They also often provide mobile PCs with wireless capabilities to their employees so that they can be productive anytime anywhere, hence enhancing the company's bottom-line.

In this article, I will explain what WiFi is and how it works. I will also discuss what you need to start working wirelessly as well as what you can expect to gain from doing so. Finally, I'll discuss the precautions you should take when working on the go.
What is WiFi? Learn the lingo

Wireless, or WiFi, technology is another way of connecting your computer to the network using radio frequency and no network cables.

Wireless works similarly to cordless phones; they transmit data from one point to another through radio signals. But wireless technology also requires that you be within the wireless network range area to be able to connect your computer. There are three different types of wireless networks:

* Wireless Local Area Network (WLAN): WLAN are wireless networks that use radio waves. The backbone network usually uses cables, with one or more wireless access points connecting the wireless users to the wired network. The range of a WLAN can be anywhere from a single room to an entire campus.

* Wireless Personal Area Network (WPAN): WPANs are short-range networks that use Bluetooth technology. They are commonly used to interconnect compatible devices near a central location, such as a desk. A WPAN has a typical range of about 30 feet.

* Wireless Wide Area Networks (WWAN): WWANs are created through the use of mobile phone signals typically provided and maintained by specific mobile phone (cellular) service providers. WWANs can provide a way to stay connected even when away from other forms of network access. Also, be aware that additional charges are often associated with the usage of WWANs in some locations.

How do I get started?

The only thing you really need to go wireless (in addition to a mobile PC) is a wireless PC Card. Depending on the age of your mobile PC, the card is either built-in or needs to be inserted in the PC Card slot and includes an antenna. In addition, you can also use wireless keyboards and mice, which can provide more freedom and flexibility when you're working in your office.

It's always good to research the available hotspots in the area you're planning on visiting (whether a neighborhood in your city you're not familiar with or a city on the other coast). You can use Bing to find hotspots when you travel.

As you head out in this brave new world of wirelessly connectivity, you can connect to a wireless network (whether at home, at work, or on the go).

* Windows 7
* Windows Vista
* Windows XP

Working wirelessly: What's in it for me

Working wirelessly can offer you the following benefits.

* Flexibility: The lack of cables that comes with wireless networking enables you to roam with your mobile PC. You can roam from your office to a nearby conference room for a meeting, or from the couch in the living room to a kitchen for a snack. For example, if you're working wirelessly in a meeting you can printout a report for a co-worker without having to leave the meeting.

* Time-saving: If you're waiting for an important response you can use your mobile PC to monitor your e-mail even when you're in meetings or at lunch. As soon as you get the data needed, you can promptly forward it to your customer rather than wondering whether the information has come in while you were away and having to run back to your office between meetings and other commitments.

* Increased productivity: Working wirelessly enables you to turn down times between meetings or while in transit into productive time. For example, you may be attending a conference and just found out that one of the sessions you were planning on attending has been cancelled. Rather than waste the next hour, you can check e-mail, start compiling your trip report, or order your son's birthday present.

* Easier collaboration: Using wireless mobile PCs, you can easily share files and information with others. For example, you can collaborate on a presentation with colleagues during a flight delay in an airport lounge, or you can share the syllabus of a course while attendees so that they can take more digitally during the class.

What should I worry about when working wirelessly?

When working wirelessly from hotspots and public places, you are responsible for ensuring the security of your files and your mobile PC.

To make network access easier for their users, public hotspots typically leave all security turned off. This means that any information you send from a hotspot is most likely unencrypted, and anyone within range of the wireless LAN, whether at a next table or in the parking lot, can access and use your Internet connection, and look at your unprotected information.

WiFi gives you the freedom to go anywhere and still be connected to your office, your family, and other important aspects of your life. Your virtual office can now be an ice cream parlor in a seaside resort. Embrace and enjoy the flexibility that WiFi affords you.

Setting up wireless printer Brother MFC 7840W Need to know my wireless network settings for my NETGEAR WTG624 v3 1. SSID (service Ste ID or Network name) 2. WEP Key if needed 3. WPA-PSK Password if needed 4. LEAP user name (if needed) 5. LEAP password


Log in to the management console, if the settings have changed you will have to reset the router to the most basic settings then start it up again, do this by turning to the back of the router, most routers have a pin sized hole in the back, stick a pin down that hole and hold it steadily pushed down for 5 to 10 seconds, release and wait 5 to 10 seconds and try again, hope this helps..

I want to make that router ip address like 192.168.11.1(for example). My office network start from 192.168.1.1.


You could setup two different profiles, one for each wireless router.
Configure your home wireless router with a different SSID and encryption setting to the office wireless router.
Then configure the wireless card in your laptop with two different profiles, one for the office wireless router and one for the home wireless router. When you want to use the home or the office wireless router, just call up the profile you require.

iR2200 as a printer/scanner - wireless network configuration


You need to hook an ethernet cable into your network. You could get a wireless router to extend another one and connect via ethernet into that if you prefer.

For setting up network settings, do you have the Network Guide?

Go to page 2-11 and follow the instructions there.

You can click the DHCP icon and hopefully you'll get an IP address etc. (you may have to restart using switch on right hand side of copier to turn off, wait a while then turn back on). Once you have an IP address click on the DHCP icon again to make sure it's not filled in with black and save settings.

IP address must be in same range as other devices on your network e.g 192.168.1.x or 192.168.0.x (only specify a number for x between 1 and 254, must not be used by another device). Subnet mask must be same as for other devices. It's probably 255.255.255.0 Canon Network ScanGear 2.21 (don't get the colour version) can be found on the Canon website (google it). Instructions for scanning are in the manual included with the download.

The mail function works fine on my home wireless network, but won't work on the office wireless network. I've occasionally found this problem with some hotel wireless systems. Other internet functions work fine. I get a message that Port something or other has timed out.


the mail is needing two servers to work:
- pop server to get your mail, you can acces to it everywhere
- smtp server to send mail, you can only use it from your home wifi.

To send mail from evrywhere, you had to go on your provider website

ok to find your wirelessnetwork name on the bottom right of the screen when in windows, there is a picture of a monitor (computer screen) right click on that little picture and select network and sharing centre by clicking, this will bring up all the information you need to know by clicking on what you want to know, hope this makes sense.
