Computer connected to non-existent network

[Chascade]

I have a router named DEF, it was previously named ABC

 

Everything else is working on all devices connected both Wi-Fi and ethernet to DEF.

 

However one of my desktops still thinks it's connected to ABC and it's Ethernet network connection says that ABC is the name of the network.

 

ABC just should not exist anymore, only DEF. And in fact I have internet but when I go to my router to check on all connected devices, my desktop Mac address does not show up even though I can confirm my desktop has internet..... How can I fix this?

 

I have tried

IPconfig /release

IPconfig /renew

 

But my desktop still is connected to ABC.

If its not recognizing it as what it should, the only way really around that is to set things(your router rather) back to factory default and redo the configuration manually including the renaming part for your network. Also, it sounds like it could also be your network device malfunctioning and failing to recognize it properly so I would make sure that you ensure that your ethernet card is fully up to date with the latest version of its drivers. Also when you ran the ipconfig command, did you include the network adapter's name at the end specifically the one of your ethernet card? Like for example, lets say it were named Solstice, it would be something like 'ipconfig /release Solstice' without the quotes.

No I did not put the network name following the release command but I thought that was insinuated by default.

 

 

I don't think it has anything to do with the router though because every other device I'm connected to in the house, all 15, see The network name as DEF, and no longer ABC.

 

I'm rather confident the driver on the desktop is up to date. I will try the release command with the network following it but I don't have any hope really

have you tried the network reset option?
