When I'm not traveling, I work from home. At home, I use Zoom for teleconferencing as well as MS Teams (if I have to).
I have my MacBook Pro 15 inch plugged into a USB hub which connects it do dual monitors and via ethernet to Gigabit ethernet (well 1gig down 50mb up) from spectrum. As a backup, my Pixel 4XL can provide my Google FI tethering (T-Mobile,Sprint, US Cellular) and I have T-mobile hotspot I can use.
Home network is Ubiquiti with an Access point in each room as well as ethernet switches where hardwire connections are called for.
Pretty used to and already set up for working from home.
