If the first one is an ethernet/highspeed capable then try that one. Disable the #2 and try the first one. You should be able to RIGHT click on whichever one says connected and then click on REPAIR. I don't know why it wouldn't give you a repair option.
If none of that is possible or works...maybe your ethernet adapter has gone bad or is bad.
I'm still trying! LOL
Other advice that helps me a lot is start all over. Literally go to your router or modem (Whatever) unplug the cable that is going to your computer and replug it in. In a different port if you have another one available. Treat it likes its the first time you are hooking up the computer. That works for me sometimes/finds missed steps.
Let me know.
