Wireless Network

How do you set up your wireless network to require login before the Internet can be accessed on it?
How can I set up my wireless network so that a username and password, or a simple login button being pressed is required before the Internet can be accessed on it? I’ve seen it at On the Border and most hotels, and I am wondering how I can do it with my own wireless network.
Thanks!

That different from what you can do at home. On those sites, you’re logging onto some authentication server that checks your status as a paying customer.
At home, you set up WPA or WEP encryption on your router, and each device that connects must provide the proper key before the connection is authorized. Usually, you only have to provide the key one time, and future logins are automatic. But it protects your network from intruders and encrypts the data so people can’t sniff it.

To straighten the cables and wires behind your computer desk or home entertainment system, then you need an organizer of the cord. This product can be an effective way to make cable management and not have to cost much and can be very useful. The right product is inexpensive and you should be able install in seconds. Try to find a cable management product that has no small parts that can break down over time or conduct. The ultimate goal is simply get your cables organized and spaced so that it can not become entangled.
Many times people try to reach their own cable management system, for example, wires hanging from hooks or tape. These solutions can last for a short period of time, but usually do not last long. Even through the use of hooks or tape, you will find that there are still going to be balls and other issues. Since the organizers of the bone are not as expensive, actually saves time in the long term simply buy something that has already been invented. No need to reinvent the wheel when the solutions currently available are very profitable in the first place.
It never a good idea to ignore the mess of cables that get tangled as you can actually cause a security risk. A tangle of electrical wires are sometimes referred to like an octopus and this could cause a fire with time. If you have an office building, you must meet the standards of fire to be legal. You can also run the risk someone traveling through wires and is injured. Young children are especially susceptible to such accidents. A very low cost you can avoid these types of accidents.
In trying to find an effective organizer of the bone, does not feel like you need to spend a lot of money. There are many different products out there and usually do not cost much. Try to find something that is simple too. There are some over-complicated products out there that have small parts that are only going to get broken at some point anyway. A good product does not depend on a trick and will last a lifetime. Other products simply can not do the job. You can group all the wires together and ultimately defeat the purpose.
When you invest in a cable management system, you will spend much less time to add or remove devices connected to your computer or home entertainment system. As things stand, they may fear having to switch to one device to another, as it may be a trouble a long time. When using an organizer of the bone change of a device will take a few seconds. Nothing will unravel and you will have to follow each string to see which device belongs to when you purchase one of the organizers and those who offer http://www.tidyline.com. With a cable system organized and not afraid to change a product of the other, and you will be safe from accidents.

Network Switch
Nov/080
There are several large network hardware vendors out there, and it can often be confusing to decide which brand to buy. Do you want a Cisco router, a Juniper router, or a Nortel router? What brand network switch or sever should your company purchase? Each specific company provides a huge amount of detail/advertising on why you should pick their solution. I decided to congeal some of these product details and provide an overall list of features that your company should be looking for in their enterprise networking hardware.
No matter what type of business vertical you are in, or where you are running your company from, networking hardware is a critical aspect of your business. The five key features your network hardware and network infrastructure should provide are:
- Simplicity: A network product and OS that is extremely simple, logical, and easy to operate will make everyone’s life easier. Network hardware that is simple in installation and execution, but provides the infrastructure for complex company communication, is a must have.
- Security: Your enterprise data is your company’s most valuable resource. Whether it be client data, financial data, or intellectual property data, it is extremely important that your network provides the protection and access control for this data. Your brand of Network hardware can mean the difference between an occasional security breach and a perfect record of protection.
- Speed: It is vital that your enterprise network is running at the speed of your business. It should never hinder your company’s work flow, whether it be accessing data within your company’s network or at global access level. The network equipment that you utilize is the engine that runs your entire company’s network infrastructure.
- Scalability: It is very important that your network be scalable with your company’s growth and downsizing. A network that is not scalable can incur unnecessary cost for your company and unwanted hardship on enterprise efficiency. Scalability means a network infrastructure that offers open source flexibility- the ability for your company to not be locked-in to one specific solution, but instead posses the capability to utilize the best market technology available.
- Savings: Maintaining a network infrastructure can often be a very costly process, and can tip a company’s earnings in one direction or the other. Finding network hardware that is both cheap and reliable is quite the difficult task. Depending on where you look, buying a used cisco router or refurbished cisco switch can sometimes mean the difference in simplicity, security, speed AND scalability. However, it is equally as important that you don’t break the bank building up your company’s network infrastructure. The key is to find a reliable network hardware vendor- whether it be a used network hardware reseller or a direct seller, make sure that they are clear-cut and trustworthy.
Beyond this list, there are basic consumer guidelines that you should follow when purchasing network hardware. One of these components is a vendor’s warranty- make sure they clearly state that they offer a warranty on your network hardware purchase so that if your requirements change, you don’t end up paying the cost.

Gartner’s Inc. independent research had shown that as much as half of network problems in the healthcare industry are due to an inadequate or substandard cabling infrastructure.
The network infrastructure represents the backbone supporting most IT functions. Today’s healthcare centers’ networks need to accommodate not only an enormous volume of data generated by the modernizations that technology brought to medicine but also need to comply with regulatory standards.
Telecommunications Industry Association’s (TIA’s), TR-42.1 Engineering Subcommittee formed in 2004 a task force group with the mission of bringing awareness within the healthcare industry of the benefits of having a comprehensive strategy for structured cabling design and installation that is unique to this industry. Most seasoned structured cabling contractors are aware that TR-42.1’s developing guidelines. These guidelines are meant to assure that telecommunications infrastructures for the health-care industry are adequate and universal.
Some of the areas covered in the guidelines TR-42.1 are listed below:
The cabling infrastructure is critical in designing networks that are flexible, fully integrated and accessible. In today’s healthcare environment Ethernet networks that are IP-based are most suitable to provide the transmission of the large quantities of healthcare related data in a rapid and accurate manner. They support the many applications such as voice, data, video, monitoring and control.
Transmission speed and bandwidth are important factors that determine a “high performing” network. Having a robust network infrastructure is more than a mere necessity. In healthcare facilities a network that fails can lead to far bigger problems than poor network performance, it can be life threatening. Gartner Inc. research firm concludes that “The wiring plant is arguably the most important part of the network. Spend the time and money to ensure that what is installed will be able to support the environment well into the future. …”
Considering that hospitals are built to last for more than 50 years the cable plant needs to be built to perform adequately for its lifecycle of about 10 years. Gartner research has shown that cabling infrastructure represents a very small percent of the IT designated resources (around 2%-5%) yet it can account for up to fifty percent of the problems. This demonstrates that an incremental increase in cabling investment can lead to an exponential increase in network performance, robustness/reliability as well as productivity and patient safety, patient safety being a major driver of the healthcare facilities network design.
Given these statistics hospitals in North America should project and plan for the total cost of ownership of the network infrastructure over its expected lifespan, rather than initial installation costs as well as consider hiring contractors that comply or exceed the TIA’s TR-42.1 guidelines.

Wifi Wireless

Securing your wireless access point is imperative. There have been several cases where people drive up and down residential neighborhoods “stealing” WiFi access – what are they using it for? They could be downloading child pornography, using the open access point for terrorist activities, or perhaps they’re downloading copyrighted material like movies and songs. Regardless of what they are using it for, you want to ensure that your access point is secure.
Securing your access point is very simple, at a very high level you need to ensure that your computer contains the latest patches and updates to ensure it has access to the latest security services. You also want to make sure that your wireless access point has the latest updates as well.
You can visit the wireless access point manufacturerÂ’s site to see if there are any updates available. They will also provide step-by-step directions for updating the firmware in the device.
Do not underestimate the web either – do a search on the hardware you are using and you will find a lot of information on securing that particular hardware.
So how do you secure your wireless access point and what technologies do you use?
The WRT54GC features all the latest wireless security settings such as WEP, WPA Personal, WPA2 Personal and WPA2 Mixed Mode. You can also choose between AES and TKIP encryption.
WEP – or Wired Equivalent Privacy is a method to secure wireless networks. WEP is not very secure, and has been cracked easily with readily available software within minutes.
WPA – or Wi-Fi Protected Access (and all flavors) is much more secure than WEP. WPA is highly recommended to be used, along with a pass phrase that is longer than a typical 6 to 8 character password. For installations that I have performed, typically we have chosen pass phrases that are between 8 and 63 characters long and that are dynamically (randomly) generated (most pass phrases that I select are 63 characters in length).
WPA2 – is more secure than WPA and fully implements the mandatory elements of IEEEE 802.11i standards.
AES – also known as the Advanced Encryption Standard is one of the options available to you to secure your wireless connection.
TKIP – known as Temporal Key Integration Protocol, is another security method to protect wireless access points. TKIP may be more secure than AES, but it may slow down the connection between your computer and the access point.
So how do you secure your LinkSys WRT54GC wireless device?
Assuming that you have already have access to the device and have set it up, adding security is simple.
Consider changing your starting IP address – the default 192.168.x.x is pretty common and is used as a default installation. You need to alter the LOCAL IP ADDRESS. This is found under Setup > Basic Setup. You can also set the Maximum Number of DHCP Users.
Next under the Wireless option name your SSID – make it original! Too many people use the default “LINKSYS” or “DEFAULT”. Use something that will not identify you or your location – I’ve seen some of my neighbors use their hobbies, not wise. You should also consider DISABLING the Wireless SSID Broadcast.
Under the same option, click on Wireless MAC Filter. Find out the MAC address for the devices that will connect to your access point, and enter them here. This provides an additional layer of security, even though MAC addresses can be spoofed. Remember to ENABLE the option and PERMIT PCs LISTED BELOW TO ACCESS THE WIRELESS NETWORK.
On the LinkSys WRT54GC there is also a button that reads “WIRELESS CLIENT LIST” clicking this will show you who is currently connected to your access point.
Finally clicking on WIRELESS SECURITY option, select the SECURITY MODE (recommended WPA PERSONAL or WPA2). Choose the ENCRYPTION (AES or TKIP) and enter the PASSPHRASE – you have up to 63 characters in length, use them all up! Finally set the KEY RENEWAL. I use 3600 seconds.
And there you have it – your wireless access point is now secure! The next step is to have your computer access the wireless device, for this you need to take some additional steps. The next part of this article entitled “Connecting Your Secured LinkSys WRT54GC to your Windows XP Laptop or Desktop” walks you through connecting your Windows XP laptop or desktop to the LinkSys WRT54GC that you have just secured.

Ethernet Patch

The concept of using equipment cabinets to house data processing is a branch of railroad switching systems in which multiple relays and wiring harnesses can be placed in a central location. This idea is very suitable for data processing applications, due to the large number of cables and patch leads are characteristic of the simplest of data systems.
The comms term "" is actually a shortened version of "communications", that was the next industry to adopt this very useful design concept. Broadcasters and other industries working with audio and video equipment found that massive cabling networks were necessary to route signals through their systems quickly end up as a pile of spaghetti without some organization. Thus, the communications industries picked up the ball and ran with it, resulting in more advanced designs of the patch bay and a modular approach to various components contained in a central cabinet.
The world data processing that would be lost without these cabinets Comms. It's hard to imagine large network, simply by running their data devices stacked around a room, with snakes of all kinds scattered on the floor. This may work for smaller systems, but even small LAN consists of several modules, with all the intricate patch configurations. This is where a comms cabinet becomes so important for many reasons.
A data management system uses a huge amount of electricity from day to day, and the cost is not cheap. In fact, control of energy use is one of the biggest concerns of data managers and CFOs alike. Any innovation to reduce the energy bill is a huge gain in the fourth data, and a comms cabinet is such innovation. As more devices in the home and its wiring configurations in a box, you not only have faster access to equipment upgrades and repairs, but the concentration system using patch leads significantly less energy, with a narrow, self-wiring.
A comms cabinet can be found in many sizes. There are small cabinets, often hung on a wall to save space to house one or two components as an Ethernet hub and a router. These vary in depth 6U to 21U. There are cabinets that are mounted on the floor, and these are usually found in large data centers. These vary in depth from 12U to 47U in most cases. A comms cabinet may even refer only to a component found itself in a small box equipped, such as a patch bay. Applications are endless, and how to use a comms cabinet and how big it is will be dictated by the size of the data management system and user needs.
Obviously, there are many reasons for using a comms cabinet in any data processing system. These can be very practical addition to an existing system, especially when use the extensive wiring. A comms cabinet can clean the data center core patch problem quickly, and can help keep operating costs in the deal.
