Due to the WebGUI security issue (fixed in 3.9.6.3), we recommend changing the passwords for admin login and password/PSKs for VPN profiles after upgrading the latest firmware from 3.9.6.2 or earlier.

• Support daylight saving time enabled automatically.
• Support the “Session-Based” and “IP-Based” modes options for Routing >> Route Policy.

• Corrected: An issue with the buffer & socket leakage in OpenVPN.
• Corrected: An issue with low IPv6 throughput for subnets other than LAN1.
• Corrected: An issue where WAN (static IP) reconnects often in HA hot standby mode.

• Corrected: An issue with Let’s Encrypt – Certificate Auto Renew failure (certificate domain did not match router domain).
• Corrected: An issue with failure to accessing Vigor router via HTTP/HTTPS from LAN and WAN due to buffer & socket leakage.

Known Issue

• The web portal may cause the router to be too busy to respond quickly.
• The encryption method for OpenVPN will be factory defaulted if firmware upgrading is performed from v3.9.7 to v4.3.1 or above.
• When the firmware is downgrading via “System Maintenance >> Firmware Upgrade”, one might have a chance to experience a config compatibility error, which causes the config of a certain function to return to the default setting.  To avoid this error, “System Maintenance >> Configuration Export >> Restore Firmware with config” is the preferred way for firmware “downgrading”. We suggest backup the config file before upgrading any firmware as well.
• To prevent potential errors when upgrading firmware, it is recommended to upgrade firmware sequentially one version at a time. (e.g., if the current firmware is 3.9.1, upgrade to 3.9.2 then 3.9.7.2, and last 4.3.2).
