I always stress the importance of getting familiar with your tools. There is nothing more frustrating than trying to figure out a tool while troubleshooting. I usually follow up this point with my popular “tool calibration” points where I go over the simple point of understanding how your tool behaves. I will cover a popular Wireshark configuration question that I cover in my training sessions, “interface configuration”. As you get more familiar with Wireshark, you might notice that there are interfaces displayed that you don’t need. In certain scenarios you might want to display only a specific interface.

no software to install, download or buy!! go to the network computing for the full article Recovering A WIFI Key From Windows Just want to start by echoing what I mentioned in the video. This video will not show you how to ‘crack’ or figure out a wireless password of unknown network. Instead this article will show you how to ‘retrieve’ a wireless password that is already configured in your Windows computer. In past articles, I routinely mention that Network Technicians should be open to many things that may transcend the traditional networking space. I think every technician has been in a situation where they need to recover the password from their laptop or desktop during the worst scenarios. I remember several occasions when I was working with someone and they were using a new laptop but didn’t remember the WPA2 password on their previous laptop. Then I show them this nifty trick or I guess the kids are calling it a ‘hack’ to retrieve their password from the other computer.

As a follow up from my first video someone asked me to show the Cable Test facility within the Netgear Switch, so here it is. ... https://www.youtube.com/watch?v=FXXIplZkbS8

What could possibly go wrong? I plug the cable in, get a link light, ping something and if see no issues, I’m done, right? We’ve all done it 1,000,000 times right? I replaced two older switches with newer switches that support when gigabit speeds. As I said before, the lights are green and tested fine with a couple of pings. The other day I decided to do the Speedtest between two computers that traversed both switches. To my surprise the speeds were less than 100 Mbps. So I thought, why not document the troubleshooting steps so I could help others might encounter the same issue. I’ve said many times that you should baseline your network, your computer so you have some sort of reference for future testing. This was one example of that exact point. I knew that the computers could generate well over 100 megabits of traffic so when I saw sub 100 Mb speeds, I knew something was up. The first step was to check the laptops network speed status and confirmed that they were both connected at 1 Gbps. Then I checked my switch/switch port status and noticed the connection between them was 100 Mbps. This is where the fun starts, I went over to physically inspect the cabling and realized the cables were quite old. The jacket was deteriorating and was probably there for over 20 years. I simply pulled a new run between the switches, tested with my NetAlly LinkRunner G2 and quickly confirmed that the new cable did in fact support one gigabit speeds. I then tested the existing cable with my LinkRunner and confirmed that it was indeed running at 100 Mbps. Some people skip this last step which drives me crazy. I’ve seen analysts replace a cable, check the speeds and say “Everything should be fine“ and then walk away. Please, take the extra few minutes to test and confirm that it “actually works as expected”. In some cases something else maybe ‘broke’ and cabling was simply one part of the performance problem.
