This version specifically addressed issues relating to WiFi authentication errors with Radius .
Frequent drops in remote client connections are usually caused by timeout settings or MTU mismatches. Check the VPN logs under the Status menu. Lowering the MTU value slightly on the WAN interface (e.g., from 1500 to 1420) can resolve fragmentation issues across unstable consumer internet connections. Conclusion
The "2021" context is crucial. In 2021, Kerio Control (owned by GFI Software) was navigating the transition from legacy on-prem firewalls to cloud-managed hybrid models. The primary firmware versions active during 2021 were and the early release of 9.4 . kerio control 942 2021
