the ip address you would use to test your own network card would be 127.0.0.1
Loopback plug
Testing the network card itself involves running a diagnostic program that is usually supplied by the vendor that manufactored the card. For basic network connectivity you can start with the 'ping' command move up from there depending on what is found.
Go to network settings, run the test and then check what IP address it has assigned.
to check if your Ethernet card r INTERNET is working r not, just type the following in command prompt: ping 127.0.0.1 This command is basically used for self test of NIC(Network Interface card) card
Use the network connection utility to test connectivity, then connect to a known working internet address across the network.
To identify potential holes in network firewalls
To test whether your computer has connectivity to the network, you can use the ping command followed by a known IP address or domain name. For example, you can type ping 8.8.8.8 (which is a Google DNS server) or ping www.google.com in the command prompt. This command sends packets to the specified address and displays the response time, indicating whether the network connection is functioning properly. If you receive replies, your computer is connected to the network; if not, there may be connectivity issues.
Put the NIC in the PC, and install the NIC's drivers. Configure the NIC using Windows, so that it has the appropriate addresses on the network and the correct network protocols. Test the NIC to verify that the PC can access resources on the network.
No, you apply for them separately. TWIC card would be good to have, though.
There will be a weakness in the 2mb laptops network card. update your network card driver. Modify network settings with tcpanalyzer Check if any wires are damaged if using ethernet If wireless, stand in the exact same place, test both laptops and see what happens.
There are several IP addresses that are special in one way or another. These addresses are for special purposes or are to be put to special use.Addresses significant to every IP subnet Network AddressBroadcast AddressAddresses significant to individual hosts Loopback AddressSpecial Addresses of Global Significance Private AddressesReserved AddressesLOOPBACK ADDRESS (127.0.0.1)The 127.0.0.0 class 'A' subnet is used for only a single address: the loopback address 127.0.0.1. This address is used to test the local network interface device's functionality. All network interface devices should respond to this address. If you ping 127.0.0.1, you can be assured that the network hardware is functioning and that the network software is also functioning.
Check mechenical part, the adapter was installed prorerly and in its place. Check software part, drivers were installed properly. Try to ping the router or the desktop itslelf. It will help only in the case when the adapter was damaged.
