This is an upgrade kit that can be used to repair or upgrade an existing Sky2, Sky3, or Sky4 router. Note that if you already have a Sky4 router, this kit will not increase performance in any way. As such, it is only to be used as a repair kit if you already have a Sky4 router since a Sky4-to-Sky4 is not an upgrade. This kit will increase performance for anyone with a Sky2 or Sky3 model, so that is considered an upgrade.
The kit includes all necessary parts to swap out the component board, antenna(s), lid, and product labels. The existing case base and DC wires or POE cable must be in good condition for this upgrade kit to work. Contact WiFiRanger tech support if unsure of the condition of your existing Sky router or which kit is necessary to perform the upgrade.
