Hi TP-Link

Background:

I have a Deco M4 with 1 range extender. Supposed to cover area over 2000sq feet. Our house is under that.. Our modem is not positioned in the middle of the house, so it wasn't possible to follow your optimum setup advice of positioning the deco in the middle of the home. As a result the main unit is on one corner of the house downstairs and the extender is in the opposite side of the house. They are communicating. However, we are still experiencing a lag with speed. Main unit currently ranging between 7 - 60kbps which is slower than I would hope to achieve.

Question: If I get an additional extender, would the extender communicate with the closest other extender, or would it have to be close enough to M4 unit to improve the black spots? In otherwords, as the main unit can not be placed in the middle of the home - how can I get the most out of the setup?

Thanks for your help!
