Linux Ubuntu 18.04: Network driver crashes + install printer

I'm a Linux rookie. For a Linux power user, these are likely easy issues.

Problem 1: I bought a Brother printer a few weeks ago (new, laser printer) and trying to set it up to work via wifi, I have not been able to get it to work. I need help with setting it up to work. When I send tasks to printer, it's just Pending the entire time.

Problem 2: I upgraded from Ubuntu 16.04 to Ubuntu 18.04. Unfortunately, there appears to be a bug with this new version. The internet stops working at very random times (I could be watching YouTube, or writing emails, or even just away from my laptop- and when I return, connection is gone). When I try to find wifi networks- none display. Its as if the driver/adapter crashes occasionally. The only way at that point, is for me to reboot my laptop, and all works well again.

If you feel you can help me solve both issues, please get in touch. We can use TeamViewer of course.

Thank you all for any interest in assisting me.

Cheers!
