I am trying to build a home network with three routers and one switch. My search here and on the internet didn't yield much, partly due to every question being very specific and also me being a novice at this (at best).
I'd like to maintain two separate wireless LANs (such that devices are bot being broadcast to the other) on two subnets, while connecting both via cable to the router that connects to the internet. Trying to draft the wired network (with device types):
Internet <---> ZTE MC7010 [192.168.2.1/24] <---> NETGEAR GS105GE <--+--> TP-Link Deco X20 [192.168.1.1/23]
|
+--> HUAWEI AX3 [192.168.0.1/23]
So I've got three subnets (192.168.2.x, 192.168.1.x and 192.168.0.x), each with its own router and DHCP server. I've really tried to understand how to configure them (esp. the subnet masks), but I think I'm doing something inherently wrong here.
My goal is to access 192.168.0.x devices from 192.168.2.x subnet (and vice versa, but that's not my main concern). By setting the subnet masks of the two LAN routers to /23, I thought I could enable access to the respective subnets, but to no avail. Another concern is that, at the HUAWEI router, I can only plug the LAN cable into the WAN port (otherwise I can't get past the warning in the UI) and that I might be facing some firewall issues. However, I deactivated the firewall in the UI and checked for any other settings that could be causing issues, but didn't succeed.
Any ideas and help would be very welcome! I am really 'working' way beyond my knowledge here... ;)
