Recently, I was working on a client machine and after logging in I realized that for some reason I was unable to connect to the server. I went to the command prompt, typed IPCONFIG and hit Enter.
The IP address for the computer was 169.254.xx and the subnet mask was 255.255.255.0. The address 169.254 is an address APIPA (Automatic Private IP Addressing) assigned when no DHCP server available or reachable.
So I decided to run the command IPCONFIG / RENEW to renew the IP address of the computers. Unfortunately, this also did not work and I received the following error:
Si verificato un errore durante il rinnovo dell'interfaccia Connessione alla rete locale: stata tentata un'operazione su qualcosa che non un socket.
If this error occurs when trying to renew the IP address, there is a problem with the configuration of WinSock on the computer. Fortunately, you can read my post from online technical tips on how to fix Winsock errors in Windows.
However, this may not be the only reason why an ipconfig / renew would not work. You may also get an error like this:
Connettivit limitata o assente Potresti non essere in grado di accedere a Internet o ad alcune risorse di rete. Questo problema si verificato perch la rete non ha assegnato un indirizzo di rete al computer.
For example, if you have a static IP address, renewal will never work. You can understand if you have a static IP address by typing IPCONFIG yourself and making sure it is something other than 169.254. If so, then someone may have manually set your IP address.
Obtain the IP address automatically
This means that even if there is a DHCP server on the network, it will not get a new IP address. You can set your computer to automatically get an IP address from a DHCP server by going to Start, Control panel, Network connections . In Windows 7 and Windows 10, go to network and sharing center and click on the link Change adapter settings .
Right click on Connection to the network local or Ethernet and select properties .
On the General tab, scroll down in the list box until it appears Internet Protocol version 4 (TCP / IPv4) and highlight it. Then click on properties .
Now make sure it is Automatically get an IP address be Automatically get the DNS server address .
Now try to renew your IP address and see if you can connect to the Internet or the network. If that doesn't work, you need to make sure there is no software on your computer that could block all the ports on your computer.
Other possible solutions
Disable any firewall software and remove or disable programs like Zone Alarm and Norton Internet Security as they can sometimes interfere.
Finally, the problem of not being able to renew your IP address may be due to the network interface card (NIC) itself. It may be with the drivers, so download the latest drivers and update them.
You can also check if it is a problem with the network by connecting the computer to another device such as a cable modem or another router and checking if it can connect to the Internet. If so, it could be a problem with the router assigning IP addresses and it would be easier to reset the router.
Another rare problem could be a defective network cable or interference from another electronic device. Try changing the Ethernet cable to see if this solves the problem. If not, make sure that the cable is not close to large devices that generate an electromagnetic field. This can cause crosstalk between the wires inside the cable.
If nothing works for you, you can try running the built-in Windows troubleshooting tool even if you're using Windows 8 or Windows 10. The link shows the process in Windows 8, but for Windows 10, just click Start and type in troubleshooting to open the troubleshooter. Make sure to click Internet connections at the top.
This tool can solve darker problems that I haven't mentioned here. I hope this helps! If not, post a comment with your mistake and I'll try to help you! To enjoy!
