How to choose the right wireless router?

One necessary device in the wireless local area network is the wireless access point, also often called wireless router. When making a selection regarding a wireless access point or a wireless router, we need to consider several parameters. So, what to consider when buying a wireless router?


Wireless Access Point (WAP)

Wireless Access Point (WAP) is a device that is used to connect one or more computers to an existing physical wired network. Wireless access point is a crucial item in the wireless to wired LAN (Local Area Network) connectivity that is responsible for negotiating a connection between the end user and usually a wired LAN.


NET SEND command

The NET SEND command is a tool that allows sending inline text messages over the network. NET SEND command is a very simple utility used to send short messages from one computer to another one.


Server Net Commands

Server NET commands are used to create, delete, modify, configure, and manage computer resources as they relate to networking. Server NET commands can also be used to display information about shared or network related resources.


NET SHARE command

NET SHARE is used to manage shared resources. NET SHARE creates, deletes, modifies, or displays shared resources. This command is used to make a resource available to clients.


NET USE command

The NET USE command is used to associate a local drive letter or device name with a shared network drive or device. Most often, the NET USE command is used for network drive mapping.


System error 67 has occurred

What does the "System error 67 has occurred" message mean?

This can happen when using the NET USE networking command.

Let's use an example. When mapping a drive on a server and launching some application using a script, we usually use the NET USE networking command. For example, the following script:



Tracert is a Windows based command-line tool that you can use to trace the path that an Internet Protocol (IP) packet takes from a source to its destination. Tracert will determine the path taken to the destination.



Pathping is a TCP/IP based utility that provides useful information about network latency and network loss at intermediate hops between a source address and a destination address.

It is a Windows based command-line tool is similar to the tracert tool in a sense that it traces the path that an Internet Protocol (IP) packet takes from a source to its destination.


Time to Live (TTL)

Time-to-Live (TTL) is a value in an Internet Protocol (IP) packet that tells a network router whether or not the packet has been in the network too long and should be discarded.

In other words, it specifies the number of router hops the packet is yet allowed to travel before it must be discarded or returned.
