How to delete "non-existing" network connection

[yoowayey]

I am using ad hoc network connection to use our DSL internet connection in my room. We have no wi-fi stuff at home, just network connection. I am having problems whenever I try to connect the network connection, it always says it has no internet access yet it is connected to the network.

Let A be the main laptop I am using right now, the one connected to the DSL model cable, the "mother" network and B be the laptop I am trying to connect to the A's network.

Right now I am using A. I tried all the possible solutions I saw in the internet such as ipconfig /flushdns, disabling microsoft adapter, disabling antivirus and changing DNS server in both A and B. Even restarting the laptops over and over again. Stilll, no improvement.

I took a printscreen of A's connections,

I had this hypothesis that the reason I am not able to have internet access in B via A's network is the existence of network JLDGN (pls refer to the picture). It is a network connection I created, used and was deleted a long time ago yet it still appears to A and B's network connections. My current ad hoc network connection is BURNING.

I don't know how to remove JLDGN, does anybody experienced the same situation as mine?
Replies and solutions will be greatly appreciated. Thank you very much.
