LAN Speed Test (Lite) measures local area network transfer speeds by writing a file of any size to a folder of your choice, then clearing Windows' file cache (otherwise read times would be skewed). Next, it reads the file back, clears the cache again, deletes the file, and finally displays the results.

NetworkLatencyView is a simple tool for Windows that listens to the TCP connections on your system and calculates the network latency (in milliseconds) for every new TCP connection detected on your system. For every IP address, NetworkLatencyView displays up to 10 network latency values, and their average. The latency value calculated by NetworkLatencyView is very similar to the result you get from pinging to the same IP address.
NetworkLatencyView also allows you to easily export the latency information to text/csv/tab-delimited/html/xml file, or copy the information to the clipboard and then paste it to Excel or other application.

Find all active devices on your network. Discover the ip address and available services for each network device. Run a speed test to check your internet connection speed.

Scan Ports
PortScan shows all open ports and additional information like host name, MAC address, HTTP, SMB, FTP, iSCSI, SMTP and SNMP services. Up to 100 threads are used for scaning large ip address ranges.

Search Devices
You can search for UPnP enabled devices, Bonjour services, Netgear router, Samsung printer and Freecom network devices. So you can find them even if you don't know the ip address.

Ping Devices
Ping any computer with 3 standard sized ping packets, with 3 different sizes, each 10 times or ping the computer continuously.

Speed Test
Test your internet connection speed by downloading and uploading data to various servers. Also a latency test and a open port test is included.

SmartSniff is a network analysis/dignostic tool that allows you to capture TCP/IP packets that pass through your network adapter. You can view the captured data as sequence of conversations between clients and servers in ASCII mode (for text-based protocols, like HTTP, SMTP, POP3 and FTP) or as hex dump (for non text-based protocols, like DNS).

On Win2K or above, SmartSniff is able to capture TCP/IP packets using raw sockets. This method has some limitations and problems, but it does not require any additional installation. A better way to capture TCP/IP packets is to install the open-source WinPcap capture driver, functional on Windows 98 and later.
