I have been experimenting with RPi for the past few months, and when I first got back into it I lost a couple hours diagnosing strange issues that ultimately all led to faulty SD cards. These are decent Samsung cards that work fine in an action camera, but the Pi was frequently dropping SSH sessions and even disconnecting from the network intermittently. Eventually I tried other cards with better results. Since then I started using ATP aMLC “industrial” Flash, which has been very reliable.

Were you using a WiFi adapter? Intermittent drops often come from undervoltage. You may need a 3.5v power adapter. Also, slow ssh can come from dns troubles: http://jrs-s.net/2017/07/01/slow-ssh-logins/ http://jrs-s.net/2017/07/01/slow-ssh-logins/

  > You may need a 3.5v power adapter Do you mean a 3.5A power adapter? The Pi runs at 5v. I have one running on a 2.0A adapter and it's been running for a few years now. Though it uses ethernet so there's less power consumption compared to one using WiFi.

    >> Do you mean a 3.5 power adapter? Yeah- sorry. Trying to do this from memory. :)

  I was experiencing these issues with a known-good PSU. The same one has been working fine since I switched SD cards. Undervoltage is a common issue but easy to identify since it shows up in logs and displays the lightning bolt icon in the top-right corner of a display is connected.
