BTW, when I hover over the network connection icon in the tray, it displays Network: Internet access, Unindentified network, No network access, yet, you see I have posted this question anyway. David figured the screen I was looking. The problem was that status was not http://superuser.com/questions/934018/how-do-i-see-the-network-adapter-statistics-in-windows-7 available in my case (for some bug in my Windows session). windows-7 networking statistics share|improve this question edited Sep 25 at 6:03 fixer1234 11.2k122949 asked Jun 29 '15 at 6:13 Val 1 So the real question should be: Why is status greyed out? –nixda Jul 2 '15 at 18:34 @nixda I have created the question to ask how to open up the status dialog. I was asking for the path to that dialog. It is answered now. –Val Jul 3 '15 at 15:31 add a comment| 3 Answers 3 active oldest votes up vote 2 down vote accepted How do I see the network adapter statistics in Windows 7? Start "Control Panel" > "Network Connections" Right click one of your network connections and select "Status" share|improve this answer edited Nov 13 '15 at 9:07 answered Jun 29 '15 at 6:18 DavidPostill 59.5k18120149 add a comment| up vote 5 down vote I think you might be after something like the result of the netstat -s command. It will show you statistics like this: IPv4 Statistics Packets Received = 125858 Received Header Errors = 0 Received Address Errors = 130 Datagrams Forwarded = 0 Unknown Protocols Received = 0 Received Packets Discarded = 315 Received Packets Delivered = 126500 Output Requests = 83395 Routing Discards = 0 Discarded Output Packets = 0 Outp
their impact on services December 14, 2015 by Dirk Wallerstorfer Detecting errors like dropped packets or retransmissions on the network level is relatively easy. Figuring out if those https://blog.ruxit.com/detecting-network-errors-impact-on-services/ errors affect the performance and connectivity of your services is however https://en.wikipedia.org/wiki/Network_packet another matter. Some network errors are mitigated and compensated for by network protocols and active networking components, like network interfaces. Meanwhile, other network errors lead to performance problems that negatively affect your services.Following is an overview of common network errors and network error root causes, means and approaches of detecting such errors, and suggestions as to how monitoring tools can support you in staying on top of your services’ connectivity and performance.TCP - Your protocol of choice since 1981The TCP/IP protocol suite that we all know so well has been around for almost 40 causes of network years now. Although some alternatives have been developed over the years, TCP/IP still works well and it’s the foundation of almost all networking as we know it today. One of the reasons this protocol stack is still around is that it’s capable of compensating for many errors on its own. TCP, appropriate to the season, is the Santa Claus of protocols. It knows if your service is sleeping, it knows if it’s awake, it knows if the connections run bad or good, so [listen closely to what it says]. Your services need not worry about retransmissions or network congestion. TCP/IP does everything in its power to makes sure that your stateful connections are reliable and perform well. Nevertheless anybody running applications in production needs to understand TCP and its basics.The top five common network errorsNetwork collisionsThis is an oldie, but a goodie that’s now almost irrelevant because of full duplex switches and technolo
be challenged and removed. (August 2014) (Learn how and when to remove this template message) A network packet is a formatted unit of data carried by a packet-switched network. Computer communications links that do not support packets, such as traditional point-to-point telecommunications links, simply transmit data as a bit stream. When data is formatted into packets, packet switching is possible and the bandwidth of the communication medium can be better shared among users than with circuit switching. A packet consists of control information and user data, which is also known as the payload. Control information provides data for delivering the payload, for example: source and destination network addresses, error detection codes, and sequencing information. Typically, control information is found in packet headers and trailers.

The correct term for a data unit at Layer 2, the Data Link Layer, is a frame, and at Layer 4, the Transport Layer, the correct term is a segment or datagram. For the case of TCP/IP communication over Ethernet, a TCP segment is carried in one or more IP packets, which are each carried in one or more Ethernet frames. Packet framing[edit] Different communications protocols use different conventions for distinguishing between the elements and for formatting the data. For example, in Point-to-Point Protocol, the packet is formatted in 8-bit bytes, and special characters are used to delimit the different elements. Other protocols like Ethernet, establish the start of the header and data elements by their location relative to the start of the packet. Some
