[Important Notice] Firmware version 4.5.2 for Vigor2866 with modem codes 2–7 will not be released because the firmware file is too large, which causes upgrades from the ACS server to fail. The Web Upgrade method works successfully. If a customer requires firmware 4.5.2 for these modem codes, please provide 4.5.2 RC3 instead and advise them NOT to use ACS for the upgrade.
