How to connect routers to another router.
So. I have one router from my ISP and two AX1500 routers on my internship at a small school. However what type they are shouldnt matter. The ISP router has an ethernet cable into a switch, and from there the cables go to two individual routers downstairs, call them router 2&3. They are netgear routers of the Netgear WNDR3700 N600 Dual-band.
I haven't installed the new routers yet cause im having trouble understanding how it all works. When i replaced the both netgear routers with the AX1500's, it just created multiple SSID. The old routers were all the same SSID and i didn't have to manually connect to them and switch. When i went from router 2 and came closer to router 3 i switched to router 3 even though it was the same SSID. With the AX1500 routers, i named them the same as the netgear ones but it was still multiple SSID. Why did this happen? Is it some configuration that has to be made?
Router 2&3 have individual ethernet cables from the swtich on the upper floor inserted in their WAN ports. The netgear routers that i should change have the dhcp ip address 192.168.1.1 both of them and a lease range of 192.168.1.2 - 254. The main router upstairs is part of the 192.168.0.0 network with a 255.255.255.0 subnet mask. I wanna understand how this worked with the old routers and not the new ones. Perhaps because the old ones worked as AP and not routers, cause the AX1500 have options to be changed to AP and not routers but when i did this the problem still persisted. I could connect to the main router upstairs and the routers downstairs wheras the netgear routers only allowed me to se the SSID that was strongest and connect to it.
