E2E4: Notice - Starting from RouterOS version 7.13, significant changes have been made to the RouterOS wireless packages. This is done due to a new product development which will require more disk space for hardware drivers so we had to split it in order to maintain old products alongside the new ones. More wireless packages are yet to come.
1. When upgrading by using "check-for-updates", all versions earlier than 7.12 will display 7.12 as the latest available version. Upgrade from v7.12 to v7.13 or later versions must be done through 7.12 in order to convert wireless packages automatically. Fresh installation with Netinstall or manual package installation works in the same manner as always.
2. Drivers for older wireless and 60GHz interfaces, as well as the wireless management system CAPsMAN, are now part of a separate "wireless" package instead of being a part of the bundle package. This package can be uninstalled if not needed.
