I have a pretty broad question.  I have Omada AC1350 setup as a source of Wi-Fi for a part of my house. Originally bought to replace a plain network extended.  It works OK, but now I have two different WI-FI networks (main Linksys router and the Omada), and still have areas with poor network connection.  Looking at my options and specifically at mesh solutions.  I know that Omada has mesh capabilities, so one option is to add an Omada compatible mesh device or two.  Having faced configuration of the original Omada, I found it too "techie" for not an IT professional.  So I'm hesitant to mess up proper configuration for that additional Omada device. Or, I can go for a simplistic and highly rated mesh (inclusive TP-Link. like Deco series), which seems to be able to replace both Linksys and Omada, but at a cost, plus possible some lost functionality of my main router.

Any recommendations, inclusive specific models would be highly appreciated.
