I keep on getting a connection error message on startup

Everytime the computer starts i keep on getting a connection error saying that connection could not be found. can someone please tell me how to remove that error, plus in my internet connect tab i have some connections that I dont really need, i think that this is causing the problem. I've tried connecting with my phone once and this happened, how can i remove my phone from there and from the Network in the System preferences?

please help i've been trying to solve this issue for days now, I know that it may seem like a stupid thing to most of you, but its really bothering me!

Regards.

NVM i solved the issue
