Network preference not responding and no Wi-fi unless I restart.
Hello,
My laptop is a MacBook Pro (Retina, 13-inch, Early 2015) and it is currently Mojave Version 10.14.6. Bought this MacBook in 2017.
The issues I will be describing will be lengthy so bear it with me, please!
Issue 1
My MacBook occasionally disconnects and reconnects the internet. This has been happening for the longest time. The problem lies in the laptop and not my router, because my phone and PC have a stable connection. I've tried USB tethering and it has provided stable connection but I do not want to rely on my phone all the time. I've searched many solutions on the internet and nothing was good on my end. I've updated the OS from High Sierra to Mojave and doesn't solve it. I also booted into safe mode or used a guest account and the problem still persists. Network diagnosis doesn't really do much for me as well. If it can't be fixed then it's probably a hardware issue that I can't do much about. Reseting SMC and PRAM doesn't do the trick aswell.
Issue 2 (major issue)
At the start of the week by the time I posted this, I've encountered another Wi-fi problem which is much worse than the problem described in 1 and I would like to get this issue fixed ASAP. What happens is that my Wi-fi suddenly stops and if I try to hover my cursor on the wi-fi symbol on the menubar and click, the cursor becomes the spinning rainbow wheel. Only the right side of the menu bar is not responsive except for the spotlight search. I checked on the activity monitor and it shows that the systemuiserver is not responding so I force quit to start it up again. There's no more rainbow wheel but will happen again if I click on the wifi symbol and it doesn't seem to fix the problem. The only temporary fix to this is to restart my laptop but I do not want to keep restarting whenever the wifi stopped working. I would like to point out that this issue is intermittent.
After I restart just to get the wifi working, I just browse the browser and wait until the wifi stopped. Then, I checked the Network on system preference and I noticed that everything on the network preference is blank. However, I can't do anything on it like clicking + or something. I then check the activity monitor and it shows that the network preference is not responding. So I decided to force quit that but it still doesn't fix the problem.
The image above is basically what is going on. I've also looked for solutions on the internet and the closest that has similar problem to mine is the following link: https://discussions.apple.com/thread/7315709
Unfortunately, I've followed the instruction and it doesn't fix the issue. Once again, ive booted in safe mode and the issue still persists. Guest account doesn't help aswell. Resetting SMC and PRAM doesn't either.
I even reinstall the OS and it still doesn't fix the problem for both issue 1 and 2.
I do not want to upgrade my OS to monterey because I fear that it may invite more problem, given that my Macbook is getting old and I don't want to take a risk.
I am at my wits end and I feel like my laptop has been cursed with some badluck. Please help!
