Hello, I’m wondering if my Macbook Air 2012 13” is nearing the end of its life? The reason I ask is because when I turn on my computer from sleep mode to use it, sometimes it doesn’t connect to the wifi network that we have. it would search for it, after a while, the wifi signal is just greyed out. we use the ATT home wifi. sometimes i'll go for week and it will connect with no problems, then alll of a sudden like today it starts acting up and cant connect to the network. my iPhone, and iPad have no problems connecting the internet. it’s kind of annoying, because I never know if my laptop will connect to the network or not. i’m not a tech guy, but i’m thinking there’s a problem with the wifi thingy inside the computer. maybe it’s old or damaged. i’ve tried all sorts of things, restarting my computer sometimes help, but sometimes it doesn’t. what could be wrong with it? as i finish typing it, it finally connected. i had to hover the mouse cursor to the top right of the screen where the wifi on/off is at. I turned it off, and back on. now i’m connected. it took 30 minutes. but sometimes this method doesnt work.
