What do these termination causes mean? I have seen 4 reasons so far in my session logs.

1. User request - noticed when i restart my router, log ends there and starts a new session record.
2. Admin reset - seen when there is frequent disconnection issue, multiple logs, each session like 1-5 minutes.
3. Lost service - seen when there is complete loss of connection, also seen when there is prolonged disconnect from my side (eg. no power at home).
4. Session timeout - only 2 in my June session logs, no idea what it means.

Please correct me if I am wrong.

You can't rely on these stats as they're not always accurate in my experience
