FSSO users lose internet

[jetbt2]

We have an issue where users from the same FSSO AD group randomly lose internet connectivity.  They can lock their computer and they reauthenticate and internet connectivity is restored. Occasionally they need to do a full restart.  Unfortunately, the bank president is part of this group...

This isn't happening to everyone in the same group.

Do these users switch between wired and wireless connections often without locking/unlocking signing in/out or otherwise triggering a new AD event log?

They are on laptops but I don't believe wifi was involved. I'm checking with my boss and minion who both experienced the issue and have laptops. I've been on my desktop computer and never had it.
