My father's MacBook Air (Early 2015) has some strange Wi-Fi issues that he says he's been experiencing ever since he got it.
I finally took the time to look at it and there is indeed something strange going on. The Wi-Fi seems to work pretty well, except that it intermittently seems to become slow for a few seconds. This makes streaming video and general browsing really annoying.
I've run a
ping google.com for a few minutes and plotted the ping time on an excel graph. And we can definitely see that it hikes 10-fold every few seconds.
I can confirm it's not coming from our router. This doesn't happen on all the other devices that are connected to it.
Things I have tried:
- Everything in this thread
- Resetting our router
- Disabling everything (Bluetooth, Airdrop, etc)
There is one thing I noticed, is that it seems that the laptop's battery has swollen a bit. I'm not 100% sure about this as I don't have another MacBook Air 2015 to compare with.
It feels like a hardware issue, as it's been like this since the beginning (according to my dad). I guess part of my question is "How do I get Apple to take us seriously and do something?" ... I can already imagine Apple telling us that we have to contact our ISP, or that we need to try restarting the computer. Thing is, I have already tried all of that stuff.
Or maybe somebody has an idea what the problem could be?
