Frustratingly slow WiFi on 2017 MBA - Catalina 10.15.3

Hello,

For the past few weeks I’ve been having a major problem with my 2017 MacBook Air’s internet connection. For no reason at all, the internet on my device unexpectedly slowed down. I’ve already checked with the admin and he informed me that he hadn’t touched any router settings. I’ve also tried to reset all my network connections and have tried multiple times to delete and restore my network config files, but still no dice. What should I do? How can I determine if the issue lies with the WiFi or the laptop? Help would be greatly appreciated. Thanks!

Some Things you Can Try:

A. Single Out this User:

See what happens when you create a new Administrator user. Log in to it, seeing if anything is different. If it works, then it is something misconfigured in this current user.

B. Remove Login Items:

Go To: System Preferences > Users & Groups > Click your Username > Login Items > Rid of Terminal, and remove any unnecessary items.

C. Reset the SMC and your NVRAM:

Sometimes when changes are made to the system(i.e. updates), system configurations (i.e. for the keyboard) become manipulated, technically. So, reset the SMC and NVRAM.

D. Try Safe Mode:

[Hold Down shift key] upon boot. In Safe Mode, corrupted system setting files (caches), are intentionally fixed.

Boot: in Safe Mode
Log In: as Same User
Wait: 30 seconds
Shut Down: the Mac
Wait: 30 seconds
Boot: the Mac normally
Log In: as Same User
See if can get this to work
