IT Engineer Life on Linksys 4400N Access Point

Ops, another 2 parcel receive at my table, according to sales department, one is linksys 4400N access point, and another is linksys switch, which need to configure and install at client house.

The switch is a manageable switch, but I’m not require to configure it, the customer just plug and play, which is home use only (Customer are rich to buy expensive switch for home use)

For this Linksys 4400N Access point, due to the customer house are very big, the wifi signal coverage require very huge, that why they require to use 802.11n Access Point.

For this N protocol, it is same as for previous version 802.11a, 802.11b and 802.11g, but it add another new function which is Multiple Input and Multiple Output (MIMO), and the coverage are double wider.

IT Engineer Experience:
I have personally tested and experience this Linksys 4400N access point. I place this access point at my house’s sitting room, and my house located at 5th floor.

There are no issue for me to access my house Wifi signal while I sitting at ground floor. It still have 1 to 2 bar signal, as my windows’s wifi status shows. (more…)

As my previous post mention on my CCNA course, the tutor share with us a cisco simulation software which name Packet Tracer.

Packer Tracer is a cisco simulation software for cisco product, it contain a lot different kind of cisco product, such as router and switches, which is for simulation use. This cisco simulation software is a very good tools for cisco learner, which to simulate configuration of cisco product.

In this cisco simulation software, I able to drag and drop different kind of router, switch, workstation, and use different kind of connecting medium, design my own network, and configure the router and switches.

After the configuration, (more…)

To upgrade my IT Engineer’s Life, I have participate my self on CCNA training pass 2 week which is Cisco Certified Network Associate. Study always cost me some buck, which I need to paid RM1800 for this CCNA course and RM880 for the CCNA exam.

The time is quite peak, 9 days to complete the whole study. Actually not 9 days, because the time table have split to half days and full days, total is 6 days course

Not much special for my CCNA class, most of the topic I have already study before during my academic time on “Network Communication” which related to IP address, Subnet mask, OSI layer and some theory. Even for the practical, such as, Category 5e cable, UTP color code, using hyper terminal, telnet and network design, I also have basic knowledge on that. (learn from senior)

On this CCNA course, I manage to learn some basic configuration for Cisco product, which previously I totally do not have any knowledge on those command, only see my senior configure before and I not understand at all.

Now, if my company have the cisco switch arrive, like previous mention on CIsco 2960 switch, I can take the oppurtunities to have real practice without using the Cisco simulation software.

After this 2 week CCNA class, 2 continuous week end, and 5 week days, almost every night 7-10pm, at last, we graduate, and get a certification of study.

Other then a certificate, (more…)

My company are using static IP address configuration, which mean each computer have to manually set an local IP address, most of the company use to do this, for better control over their network.

For using windows XP, I did not found any difficulties to shift my local IP address, but with using windows vista, the process is very slow, and always ask me for permission during the process.

Start -> Setting -> Network connection, right click on the LAN, and click property, it always pop up “Windows need your permission to continue” and while click OK, it need few second to process.

After shift the IP, still need few second to apply the setting, all this second, make me feel annoying it take more step to accomplish.

I search over the Internet, found this useful software, it able to help me shift my local IP address. IPShifter, is a good software which able to let me save few configuration. I have save 1 setting for my office, and save 1 setting for my home network.

While I back home, just plug my laptop back to the network, and simple few click to shift IP address, the setting has been change. So to the same process while I back to office.

Example like my current office setting: (more…)

As an IT Engineer, I need to provide 1st level technical support to my end user. Some how, the user are not next to me, which located in different location or different stage or even different country.

Guiding him/her through the phone are easy, if the person have some technical knowledge, but what if the person is IT dummy? Just like a chicken communicate with duck. For this case, I require to use remote access, log in to their computer and help them troubleshoot their problem.

Remote access is one of the good tools for technical support to solve the end user problem easily. Normally I will use RealVNC at my office, but problem is this software require port redirect/ port forwarding setting at the destination router, different router different setting, and also hard to guide the user do the setting at their router via phone call.

LogMeIn an alternative for RealVnc
With using LogMeIn, some people said is very troublesome, and it take many step to start using this LogMeIn remote access service. In my opinion, it is very easy to use, with few correct step. This is why I try to compile the step by step user guide for logMeIn.com for any one who need to use this service.

LogMeIn Client Side Installation

Let start at Target workstation first, or we call it as destination workstation, the computer which I need to login in (My Client Computer)

1) My client (Target) need to access http://www.logmein.com

2) Click on “Download LogMeIn for free” (For 1st time user only)

3) My client require to register for LogMeIn website, the email & password must be know by me later, so that my side able to log in the destination computer with this email as login ID. (more…)

After showing the video of how the termination process of the Tera Category 7 cable, and also some of my IT Engineer LIVE experience on Tera termination.

Just to update the cable specification and functionality.

1) Performance to 10Gb/s and beyond, far exceeding all performance requirements for 10GBASE-T.

2) Bandwidth of 1.2 GHz per pair, twice the category 7/class F specifications and the highest of any available copper system.

3) Validated for TEMPEST high-security government applications.

4) Cable sharing - Shielded design and 1-, 2- and 4-pair outlet and plug modularity allow the simultaneous support of multiple applications over a single cable, administered in a single outlet.

Soon, in a short time frame, I still have another life experience to be shown, according to my sales department, they receive a small project on category 7a installation again, will update my IT Engineer Life experience soon
