Wiring pairs could be wrong. I never tell what they are since I want to hear from you which scheme you used.

In my current setting, I have a Cisco EPC3928 router running it's own DHCP server, and handing out addresses on the 192.168.178.X subnet to machines connected to it, on the LAN interfaces. In the garage, I use a time capsule in bridge mode (no wifi) to provide two additional cable connections for my NAS and a laptop. With this setting, I have no connection problems.
I now need a WiFi connection on the 1st floor and the Cisco signal is not strong enough. Because of the way the house is built, the cable has to go through the garage to reach the first floor, so I was thinking of replacing the time capsule with a Netgear switch, and connect the lan cable that takes the signal to the 1st floor to the time capsule, this time with WiFi enabled.
The problem is once I connected the switch to the network , I get irregular internet service on the network. For instance, when opening a web page, Chrome says "resolving host" or gives a timeout error saying my device not connected to the internet. If I refresh, sometimes the connection goes through.
Can you help me? What is wrong with my idea for my home network? Why is the switch failing?
Thanks in advance
