No SSID Broadcast From Wireless Router & Access Point

Yesterday night I faced a strange issue related to wireless connectivity on my laptop. I could not find SSID from my router. First I thought it was my Laptop wireless adapter's issue as there are no other networks. My desktop does not have a wireless adapter so I have no other option to verify whether it is the router issue or my laptop issue. Today morning I went to one of my friend's house and checked whether my laptop is able to see WiFi from his Access Point. Yes, my laptop is seeing it from his Access Point. So it is clear that my laptop adapter is working fine and the culprit is my Wireless Router. The major steps I performed on my router to fix this issue are described below in a systematic order.

Dr.Watson Postmortem Debugger has Encountered a Problem and Need to Close

Yesterday night while working on my computer I saw the error message "Dr.Watson Postmortem Debugger has encountered a Problem and need to close. We are sorry for the inconvenience." My computer froze when I pressed 'don't send report' button. Since I couldn't work anymore, I restarted it but again the same Dr. Watson Postmortem Debugger came up with a sorry message.

Microsoft is using Dr. Watson Postmortem Debugger to collect error reports from devices which use their Operating systems.

Communication between two APIPA computers without DHCP Server

On the last Saturday, I and my friend are trying to connect two computers directly using a USB cable and start communication between these two computers without the help of any external DHCP server. As I mentioned in my previous post we cannot use an ordinary USB cable to connect two computers directly. It may burn the USB port.

[ To know more about it please follow the link below. ]

In this project, we avoid using the router or any other DHCP servers. As we are not using the Ethernet adapters we cannot set any static IP address. So without the presence of external DHCP server and static IP address our both computers will get APIPA from Windows Operating System.

[ To know more about APIPA please click on the link below. ]

So the IP address our computers got was a 169.254.X.X range. Fortunately, the IP address gained by our compu…

Can I connect two Computers using USB cable

There are so many methods to connect two different computers and share data between them. Ethernet cables and wireless (IEE802.11 standards) are the most popular modes to connect two devices. However, you can use USB (Universal Serial Bus) cable to connect two computers and use the same connection to share files between them. Though, for this, you must use a special type of cable called Bridged USB cable. If you use a normal USB cord to connect two computers, it may damage the ports. This guide explains the difference between bridged and normal USB cables.

Connecting Two PCs Using Bridged USB Cable

The type of Universal Serial Bus cable which is used to connect two computers directly is called Bridged USB cable. It is available in two different standards. They are USB 1.1 and 2.0. The difference of standard is based on the speed of data transfer. In 1.1 version, the data transfer speed is 12 Mbps and that in version 2.0 is 480 Mbps.

How to change system date and time in Ubuntu Linux

This weekend was very interesting for me as me and my friends established a Local Area Network in their home. They have a total of six computers and two of them is running on Ubuntu Linux. After establishing the Local Area Network we implemented one propitiatory real-time simulation software on this LAN by installing the software on all these computers. But the software works fine with the integrated data from 5 computers and one computer is not connecting to it or connection rejects. So the techie in our mind got up and we start troubleshooting the issue.

At first, we thought the issue is with the compatibility issue of Ubuntu and the software. But the first Ubuntu computer is working fine with the software and in a careful analysis, it is found that that computer is functioning more efficiently than other Windows-based computers. So it is not the issue with Ubuntu. Then we confused what is the actual cause of the issue. Then I just checked the connection manager of the software and…

How to Prevent Copying Files to USB Drive From Computer Without Disable USB Port

Today early morning one of my friends called me for urgent help. He is working as a System Administrator for a small company and wants to disable copying files from working computer to USB drives (pen drives). I told him to disable the USB port and fix the issue. Then he said according to the company policy he cannot disable it. He wants the computer should read files from the USB drive but no file transfer to it from computer hard disk. So, in a nutshell, he wants to read files from the portable storage drive on his company computers but does not want to copy files from his company computer to the USB drive. He is confused that if it is possible to block writing files to the portable memory storage without preventing the PC from reading it.

I too at first confused with this strange company policy. Then I realize, it is very simple to do. We can enable write protection on USB by GP edit or Registry Edit. If Write Protect is enabled on Universal Serial Bus, the computer can read files…
