Lan network by means of NETGEAR ORBI ROUTER RKB50

Hi. Is it possible to create a Lan network switching netgear orbi router RKB50, linked by means of ethernet to the fastweb router, 6 pc in 6 different rooms with a LAN cable?

Using 2 satellites by means of a wifi network, I observed frequent disconnessions and it noises my work.

In 5 of 6 rooms, pc are to be connected by TCP/IP protocols with a FIle Maker pro database in a pc server located next the netgear orbi router and when linkin with satellited go down also for few minutes, all the job is lost.

I ask: using a lan network between netgear orbi router and the 6 pc (pc server ed the 5 pc in the other 5 rooms) I have a stable connection?
