I've been working from home for close to a month now (about a week or so before my employer made it mandatory). A few comments:

Internet: I'm finding that the pitiful upload speeds Spectrum provides--even while on the ~940mbps/Gig plan--are a hindrance on occasion. (I'm a software developer that has to do a fair bit of uploading to work's servers.) If AT&T ever starts offering Fiber here, I'm definitely going to take them up on it. Even a 5G connection from them that does better than ~40mbps upload speed would be preferable. Fortunately, other than YouTube and Netflix taking a few seconds longer to start playing video, general internet use seems fine.

Home network: Fortunately, my personal setup was already pretty good prior to all of this happening (Ubiquiti ER-Lite router + UAC-HD access point + Netgear/Mikrotik 10GbE switches). My desk is near the router, so I use Ethernet for my work laptop even if it's not strictly necessary to.

VPN: My work uses GlobalProtect with mandatory 2FA to log in, so no worries about security. USB write access is also disabled by IT policy, though reads are still okay. VPN speed tests could be a bit better--I just got something like 180mbps down and ~30 up using speedtest.net now. (Without VPN, I can get ~750mbps down on Wi-Fi using my MacBook Pro--and Spectrum's advertised speeds over Ethernet.)

Conferencing: My team has a daily Microsoft Teams meeting (formerly Skype for Business). It seems to work okay for conferences, but how chat works in Teams takes some getting used to compared to Skype. An organization I'm part of outside of work is using Zoom for meetings now and it seems to be working well too.

Also, for our work meetings, we never use our webcams, so no worries there. However, there's definitely a difference in audio quality depending on what team members are using. Occasionally hardware and/or software issues cause garbled audio, too. I use a Jabra headset that the IT department gave me when I went in to get Skype reinstalled and I've gotten no complaints.

Work/Life Balance: Not that we're particularly doing much of anything while there's a shelter in place order going on, but working from home does make it easier to work and be expected to work outside of "normal" business hours. I'm not sure this is a good thing long term if this causes organizations to reconsider on-site employment. On the other hand, I wouldn't mind my eight hours being done predominantly in the evening as long as I'm only expected to do 40 hours a week or so.

Anyway, hopefully everyone's staying healthy. May we return to something approaching normal as quickly as possible (though I'm surprised that it's already been a month).
