10 Ways to Boost Your Wireless Signal

Troubleshooting your network's wireless performance can seem like a baffling exercise, until you consider that there are really just two main factors to consider—coverage and speed. Yes, you can have one without the other. For example, it's great to have a screaming-fast wireless network, but if you only get decent speed when your laptop is right next to the router, the speed isn't worth much. You need to boost the signal's range. If you can barely open friends' Facebook pictures when you're in the same room as the router, then we're talking about problems with speed.
In general, however, these issues can all be lumped together as performance issues. You want both your speed and coverage to be as robust as possible. There are several factors that can have an impact on both aspects of performance.
Distance can certainly impede performance. You may have a room in your home or office that is simply too far from your wireless router. Even the way your home or office is structured could be a factor in poor wireless performance. If the signals have to bounce around too many corners to reach your wireless devices, that can cause problems (although a technology in newer routers called beamforming can help direct a router's signal to wireless clients).
Interference with the signal can be a big factor in performance, too. If you live in an apartment building, your home might be inundated with signals from everyone else's routers. Maybe structural interference is the culprit. If your furnace, washing machine, and dryer are all between your router and your laptop, that won't help.
Maybe it's the software you're using. Routers need firmware updates just like everything else—and sometimes, even out-of-the-box, the hardware can be improved with a software update.
These are just a few of the possible reasons your connection might be poor (or nonexistent). Fortunately, there are many ways to extend your wireless signal, and most of them simply involve a bit of tweaking to your wireless network. Some involve purchasing reasonably affordable components. We'll walk you through ten of the most useful fixes for your connectivity woes.
View the slideshow for ten ways to extend your Wi-Fi signal. Some of the suggestions require no additional hardware or software to purchase, while others may require a small or larger investment, depending on the particular performance problem you're experiencing.

Basic information about Wireless Security

Wireless security is the prevention of unauthorized access or damage to computers using wireless networks. The most common types of wireless security are Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA). WEP is a notoriously weak security standard.

The password it uses can often be cracked in a few minutes with a basic laptop computer and widely available software tools. WEP is an old IEEE 802.11 standard from 1999 which was outdated in 2003 by WPA or Wi-Fi Protected Access. WPA was a quick alternative to improve security over WEP.

The current standard is WPA2. Some hardware cannot support WPA2 without firmware upgrade or replacement. WPA2 uses an encryption device which encrypts the network with a 256 bit key. The longer key length improves security over WEP.

Many laptop computers have wireless cards pre-installed. The ability to enter a network while mobile has great benefits. However, wireless networking is prone to some security issues.

Hackers have found wireless networks relatively easy to break into, and even use wireless technology to hack into wired networks. As a result, it is very important that enterprises define effective wireless security policies that guard against unauthorized access to important resources.


Wireless Intrusion Prevention Systems (WIPS) or Wireless Intrusion Detection Systems (WIDS) are commonly used to enforce wireless security policies.

Topology in Network Design

In computer networking,topology refers to the layout of connected devices. This article introduces the standard topologies of networking.
Think of a topology as a network's virtual shape or structure. This shape does not necessarily correspond to the actual physical layout of the devices on the network. For example, the computers on a home LAN may be arranged in a circle in a family room, but it would be highly unlikely to find a ring topology there.
Network topologies are categorized into the following basic types:
  • bus
  • ring
  • star
  • tree
More complex networks can be built as hybrids of two or more of the above basic topologies.
Summary
Topologies remain an important part of network design theory. You can probably build a home or small business computer network without understanding the difference between a bus design and a star design, but becoming familiar with the standard topologies gives you a better understanding of important networking concepts like hubs, broadcasts, and routes.
