IT Forum / General cleaning Tips of your computer.
« on: March 11, 2014, 06:06:52 PM »
Below is a listing of general tips that should be taken when cleaning any of the components or peripherals of a computer as well as tips to help keep a computer clean.

1. Never spray or squirt any liquid onto any computer component. If a spray is needed, spray the liquid onto a cloth and then use that cloth to rub down the component.

2. You can use a vacuum to suck up dirt, dust, or hair around the computer on the outside case. However, do not use a vacuum for the inside of your computer as it generates a lot of static electricity that can damage the internal components of your computer. If you need to use a vacuum to clean the inside of your computer, use a portable battery powered vacuum designed to do this job or try using compressed air.

3.When cleaning a component or the computer, turn it off before cleaning.

4. Be cautious when using any cleaning solvents; some individuals may have allergic reactions to chemicals in cleaning solvents and some solvents can even damage the case. Try to always use water or a highly diluted solvent.

5. When cleaning, be careful not to accidentally adjust any knobs or controls. In addition, when cleaning the back of the computer, if anything is plugged in, make sure not to disconnect any of the plugs.

6. When cleaning fans, especially the smaller fans within a portable computer or laptop it's suggested that you either hold the fan or place something in-between the fan blades to prevent it from spinning. Spraying compressed air into a fan or cleaning a fan with a vacuum may cause damage or back voltage to be generated.

7. Never eat or drink around the computer.
8. Limit smoking around the computer.

IT Forum / Is your PC slow? 10 tips to speed up your computer.
« on: March 11, 2014, 04:37:36 PM »
Here are 10 tips and tricks to boost a Windows PC:

1. When your system starts, a lot of programs auto load which slow down your machine. Therefore, it is suggested to remove unneeded programs at startup with the help of Microsoft's MSConfig tool. Go to Start > Run > type "msconfig". Go to the startup tab and uncheck the programs you don't want to load whenever the system boots up. Click OK and restart.

2. Your PC comes pre-installed with a lot of programs which you don't even use. They unnecessarily eat up a significant amount of space on your machine and slow your system down. Go to Control Program > Programs and Features > Unintall the programs you don't use.

3. Whenever a program runs on your computer, it leaves certain files on your machine which consume a certain portion of disc space. Over a period of time, hundreds of programs run and thousands of files pile up on your device - which eventually decelerate your machine and sometimes lead to system crash. Therefore, you are suggested to periodically delete temporary files. Go to Start > Run> type "%temp%" > click OK. A folder full of files comes. Select those temporary files and delete.

4. You are advised to timely update software running on your machine. Most of us tend to click on the "Remind Me Later" button whenever a window pops out suggesting us of any update, and we never bother to go back to update.

5. A computer is vulnerable to viruses and other types of malicious programs like Spyware and Adware. These malware load into computer memory and slow down its speed. Thus, it is recommended that you install an antivirus on your machine to check for such programs. While there are many antivirus software available for free, we would recommend you Microsoft Security Essential. Also, ensure that the antivirus installed on your machine is not scheduled to run scan during the time of the day when it is heavily used. Schedule it to run scan when you are not using the system.

6. As your PC runs, files get spread across the device in pieces - framgents. It is recommended that you defragment your disk to bring back separated parts in one place. Defragmenting disk has a noticeable effect on a slow computer. Windows 7 comes with a built-in defragger which automatically defrags at intervals.

7. By turning off Windows graphics, you can set your computer to deliver a slightly better performance. Go to computer icon on your desktop > Properties > Advanced System settings > Advanced > Click Settings under performance > Enable Adust for best performance. It will have an impact on the speed of your PC.

8. Users should optimise the browser they use as per their needs. Ensue that your brower does not have unnecessary plugins and add-ons installed which may affect the performance of your device.

9. Hard drive on your machine must be partitioned. Partioning your hard disk helps in improving the speed of your slow PC.

10. ReadyBoost in Windows 7 can use your flash memory device to add instant RAM to your PC. Plug in a USB flash drive or card and ReadyBoost is active to use. ReadyBoost is designed to help when your PC's memory is running low. ReadyBoost works with most flash storage devices.

If these pc is turned off then the other PC will lose the IP

On occasion this time, the following article will describe how to make the DHCP server configuration through Winbox on Mikrotik PC Router. Here are step by step to setting up DHCP Server Pc Router.

IT Forum / How to limit internet bandwidth usage on Mikrotik router
« on: April 25, 2013, 05:00:22 PM »

Suppose that you have a Mikrotik router which is routing both LAN and Internet packets. You want to limit the Internet bandwidth on some ports. On Mikrotik you can use Simple Queues to limit Both Transmit and Receive bandwidth. But there is no direct option in the Queue settings to limit just the Internet bandwidth, and whole network bandwidth including LAN will be limited on the configured ports.


There is a table in the firewall section named Mangle. One of the usages of  this table is  marking packets. In other words you can assign a label to packets according to desired rule. This will help you to make further decisions whole around the Firewall/Router.

Mangle table can be used to solve the problem. you must add a rule to this Table. Telnet to the Mikrotik or use it's GUI/Web interfaces go to IP -> Firewall -> Mangle add a new rule with following settings:

    chain = prerouting
    action = mark-packet
    new-packet-mark = Internet
    passthrough = yes

Here dst-address=! (Take note of the '!' mark at first) is a sample for your network. You must configure it based on you network settings. Also if you need to limit just some ports you must configure the Interface setting. Applying this rule will mark all packets whose destination is not to LAN.

After marking packets you can add a rule in the Simple Queue to limit bandwidth just for packets marked as Internet.

IT Forum / How to Test Internet Speed???
« on: February 28, 2013, 05:00:39 PM »
Why Is Internet Speed Important?

If you're browsing the web and pages take a while to load, or a video you want to watch has trouble playing, your Internet speed could be the cause. You can test your bandwidth though by using free websites.  These sites allow you to see if your connection matches up to what your Internet service provider promised you. Can Test Internet Speed

A free and trusted site is Simply load the site, and click the Begin Test button. Once this is clicked you'll get three results. Your ping speed, your download speed, and your upload speed. It's a good idea to test twice, or three times for best results. Your will likely end up with different results each time as activity on your network can influence your speed. The Speedtest results give you a general idea of what your connection speed is at the time. Ookla is the company behind and most of the other testing services as well.
Test Internet Speed With Your ISP

Another way to go about testing is to check your connection with your service provider. Your provider likely uses Ookla as well. The PC Support guide for has the major providers listed, you can go there to find your provider and your connection speed between it.
Use a Consumer Broadband Test to Test Internet Speed

The U.S. government also has a test you can use by going to Click on "Consumer Resources" and then on "Consumer Broadband Test". You'll have to fill out some information about where you are testing from first. This test is also provided by Ookla, and you'll need Java to run it. Once you enter your information you'll be able to begin a test. When you're done with your Ookla test you'll be asked if you'd also like to be tested by M-Lab. Try this too.

These tests are a great way for you to keep an eye on your connection speed, and they're easy and free. Remember though if you're downloading or uploading something you're bandwidth will be affected, so it's best to test when there's minimal activity on your network.

Thanks for reading.
