I"m not a fan of mixing brands of products with WiFi. Tend not to always work the best.
Now, modern day versions of this are now called "mesh" systems..which, really is just an extender, but they're designed to work better together. Years ago when things were mostly just 2.4, the performance hit of using extenders/mesh was brutal. As you probably know, wireless is half duplex...so...one at a time! Each additional hop cut throughput in half, and each additional client cut that throughput in half yet again. Cuz the same radio had to do "one at a time".
These days, new "mesh" systems (modern day repeaters) should have at least 2 radios...the 2.4 and the 5...and some will even have a 3rd radio. So with the dual radios, one will be used more for the "backhaul"...so the other radio can handle the wifi clients. This cuts down on the performance loss big time...that the single radio earlier generations had. And those with the 3rd radio..that will be a radio 100% dedicated to the backhaul...so even less performance loss. Netgears "Orbi" models have that dedicated 3rd radio.
Bottom line....I'd replace that current setup with a new "mesh" system where you have the router and "satellite" units all the same brand, meant to work together. Eero, Amplifi, Google Mesh, Netgear Orbi, all great products. Or...even those long time common brands like DStink, Stinksys, TPStink...they all have their similar products now.
They work really well!
Or..go Unifi. Ubiquiti recently added a new "extender" AP to go with their Unifi APs...called the Beacon. Plugs into an outlet.
Amplifi is Ubiquitis residential arm....they have a great Mesh system.
