On app i see star topology with deco router as main point:
ISP->deco S4(router)->wireless connection ->deco S4 (fist satelite) //good signal to deco router
                                   ->wireless connection -> deco S4(second satelite) //poor signal to deco router

for the first satelite i have good signal, for the second i have poor signal to the main deco router. But first satelite has good radio path to the second

Can I mannually change topology? I would like to make L-shaped topology:
ISP-> deco S4 router->  wireless connection-> first satelite ->  wireless connection-> second satelite

As this is mesh system, can be possible that it communicates in that way but I see typical star topology on app?
