Q: I have updated my Mac but now unable to connect to internet

Thanks for using Apple Support Communities, Spencer!

Since I try to limit the amount of data I use, being able to connect to Wi-Fi is very important to me. I'm not sure if you're using a Mac or iOS device, so the steps in these articles can help you with your Wi-Fi connection on the device you're having an issue with: 

Use Wireless Diagnostics to help you resolve Wi-Fi issues on your Mac

If your iPhone, iPad, or iPod touch won’t connect to a Wi-Fi network 

Take care!
