What This Code Means
Error 813 generally indicates that the connection attempt cannot proceed because a broadband/PPPoE session is already active or the system believes it is. In many home setups, PPPoE is configured on the router, making PC-based dial attempts unnecessary and potentially conflicting.
Where Users Usually See This Code
- PPPoE connections configured on Windows
- Environments where the router handles PPPoE sessions
Why This Code Appears
- Router already maintains the PPPoE session
- A previous session is stuck/half-open
- Multiple devices trying to dial with the same credentials
What Typically Happens Next
- The connection attempt stops and the system remains in its current state
What This Code Is Not
- It is not an incorrect password error
- It is not a DNS resolver problem
Troubleshooting Checklist
- □ Confirm whether PPPoE should be configured on the router rather than the PC
- □ Restart router/modem to clear stale sessions
- □ Ensure only one device is using the PPPoE credentials at a time if the ISP restricts sessions
Notes And Edge Cases
Some ISPs limit concurrent sessions; dialing from multiple devices can trigger disconnects or blocks.
