@Gabbo77,

A few things,

You should try to maximize your range and find the cause of the decreased range before looking for additional devices.

• Try moving around the router to see if there is interference from devices or appliances.
• Your Range Extender should also be placed halfway between where you want to extend your connection and your router for the best connection.
• Try changing the channel that your router is using to see if there is interference on that channel from your neighbors

If you have a larger home, you may have a better and smoother experience with Deco. However, you would still need to make sure that each mesh node has a strong connection to the main mesh node, whether it be wired or wireless.
