One last item I've needed to work out since transitioning to WFH in 2019 was a secondary connection. If the WAN drops at the office it can be an excuse to lower productivity; not in a WHF situation where you may need to go into the office to work. To avoid that, I've opted to add a Mi-Fi device to my mobile plan, which is a low cost option to ensure I've always got an IP connection. As an added bonus, it lets me work from fun locations and effectively allows me to have "work-cations" where I can enjoy travel and work
