Routing woes

    Looking for a bit of advice. I have a local LAN 192.168.1.0/24 connect to an Eircom router (192.168.1.254). I have two TP-Link Archer C9 wireless routers on the network (192.168.0/24 and 192.168.2/24). My workstation has a static IP on 192.168.1.234 and my default gateway is the Eircom LAN interface. Any users connecting via either of the two Archer routers can get out to the internet but there is no connectivity to any devices on 192.168.0/24 or 192.168.2/24 from the main 192.168.1/24 LAN. I have tried putting in a static route on the Eircom D1000 i.e. 192.168.0.0 255.255.255.0 192.168.1.7 (which is the static IP for the C9 WAN interface) but no joy. I have uPnP turned off on the C9's.

    I'm obviously missing something stupid. I have the Eircom and C9 routers on different wireless channels.

    The main reason I need to get this working is to use USB file sharing from one of the C9 USB ports.

    Any suggestions?

    Configure both C9's as access points, give them fixed IP's in the 192.168.1.x range(outside of the DHCP scope) and plug them in via their Lan ports to the Eircom router.

    I wanted to avoid that, but it does solve the problem and I enough IP space to facilitate it, thanks.

    You have three subnets, that's asking for trouble. Bridge your modem to one of the C9s, turn the other into an access point so you have a single subnet

    Thanks for the replies, guys. I've given the two C9 routers statics (for management) on the 192.168.1/24 network and set the Eircom box to handle the DHCP. All working fine now and USB shares working as required.

    Just to explain this, home routers are not the same as commercial routers.

    Both C9 networks were treating the 192.168.1.x network as the internet, which means they were NAT'ing their traffic into a 192.168.1.x address and putting a firewall between their clients and the other networks. In your case the most obvious answer is to simply create a large broadcast domain.
