Secure Your Wireless Router In The Short Term By Assigning It An Aggressive Name As more devices ship with wireless networking capabilities, it becomes increasingly important to have routers that are capable of handling connections from hardware such as tablets, laptops and mobile phones. The problem is that many routers still in use are perfectly good pieces of hardware, except for one drawback – they don’t support Wireless-N or offer advanced encryption such as WPA. With the threat of drive-by Wi-Fi theft and the risk of secure data being transferred over a non-secure connection, wireless routers without the most current security options can be temporarily shored up with just a bit of imagination. Secure Your Wireless Router with Its Name According to figures published in October 2011, Windows XP still has a respectable market share as the operating system on around 33% of all computers connected to the web. In order for users to connect to a wireless network, a wireless router typically broadcasts an SSID, or Service Set Identifier. Conclusion
TCP/IP Overview and History TCP/IP Overview and History(Page 1 of 3) The best place to start looking at TCP/IP is probably the name itself. TCP/IP in fact consists of dozens of different protocols, but only a few are the “main” protocols that define the core operation of the suite. Of these key protocols, two are usually considered the most important. The Internet Protocol (IP) is the primary OSI network layer (layer three) protocol that provides addressing, datagram routing and other functions in an internetwork. Due to the importance of these two protocols, their abbreviations have come to represent the entire suite: “TCP/IP”. TCP/IP uses its own four-layer architecture that corresponds roughly to the OSI Reference Model and provides a framework for the various protocols that comprise the suite. As I said earlier, the Internet is a primary reason why TCP/IP is what it is today. In 1973, development of a full-fledged system of internetworking protocols for the ARPAnet began.

How to Crack a Wi-Fi Network's WPA Password with Reaver How to Find Your Computer’s Private & Public IP Addresses An IP address (or Internet Protocol address) identifies each networked computer and device on a network. When computers communicate with each other on the Internet or a local network, they send information to each other’s IP addresses. Your computer likely has public and private IP addresses. Public vs. IP addresses can be either public or private. Assuming you’re behind a router performing network address translation, you have two IP addresses that matter. For example, if you’re hosting a server on your computer, people on the Internet will need the public IP address from your router to connect to your server. If your computer is connected directly to the Internet with no router sitting in between, your computer’s IP address is a public IP address. Finding Your Private IP Address To find your computer’s IP Address on Windows, open the Control Panel and select View network status and tasks. Click the name of your Internet connection to view its status. Finding Your Public IP Address
Wireless Tips – Does Your Wireless Router Keep Disconnecting or Dropping the Connection? I’ve had a Netgear wireless router for about a year now and it’s been pretty good until a couple of weeks back all of sudden my wireless connection kept dropping or I could not connect to the router unless I restarted the router! It was a royal pain in the butt, but because I’m lazy I didn’t get around to fixing it earlier! If you’re in the same situation, here’s what you can do to fix the problem! The issue is usually caused by one of two things: the driver for your wireless card or the firmware version on your router (basically the driver for the router). First, you’ll need to go to the web site for the manufacturer of your computer: Dell, HP, Toshiba, etc and go to their support or driver downloads page. Dell – HP – Toshiba – Sony –

What You Need to Know About the Java Exploit On Thursday, the world learned that attackers were breaking into computers using a previously undocumented security hole in Java, a program that is installed on hundreds of millions of computers worldwide. This post aims to answer some of the most frequently asked questions about the vulnerability, and to outline simple steps that users can take to protect themselves. Update, Jan. 13, 8:14 p.m. ET: Oracle just released a patch to fix this vulnerability. Q: What is Java, anyway? Q: So what is all the fuss about? Q: Yikes. Q: How do I know if I have Java installed, and if so, which version? Either way, it’s important not to get too hung up on which versions are affected, as this could become a moving target. Q: A site I use often requires the Java plugin to be enabled. Q: I am using a Mac, so I should be okay, right? Q: I don’t browse random sites or visit dodgy porn sites, so I shouldn’t have to worry about this, correct? Q: Okay, I think I’m covered on Java.
