The easiest way to fix this problem is to replace one of your routers with a switch. The way you have it now your routers will be fighting over which default gateway to use and it ends up creating a big networking mess.
It's not meant to work that way which is why that set up isn't working for you. There are ways to use a router as a switch but it's not considered to be a reliable set up,...it's just not meant to work like that, you would much better off just purchasing a switch
Switches are cheap and easy to set up, just plug it in to one of the routers ports and plug your other machines into the switch. Your unidentified network problem will most likely just go away once you remove the extra router and install a switch.
If you really want to save the money for the new switch or just like to mess with networks you can use the instuctions below to set up a dual router network.
Installing a router to work as the second one on a home network requires special configuration. Do the following on the second router to ensure it (and the devices attached) function properly:
- 1. Connect as local device or bridge - If connecting the second router via Ethernet cable, plug it into one of the LAN ports on the first router. If connecting the second router wirelessly, ensure the second router is set for client mode. Note that some home wireless routers do not support client mode; these must be connected by cable. Check your router documentation for details on its client mode configuration support.
2. Check / change IP address - Most home network routers use a default IP address setting. Often, these default IP addresses will not work in a two router environment. Check the second router's IP address value and reset it if necessary to work within the valid address range of the first router (and to not conflict with any other device on the network).
3. Disable DHCP - To avoid IP address conflicts between all of the devices on the home network, only one of your two routers should assign addresses via DHCP. All mainstream routers provide an option to disable DHCP as part of the router's configuration screens.
Instead of adding a second wired router to an existing network, consider adding a network switch
instead. A switch accomplishes the same goal of extending the size of a network, but it does not require any IP address or DHCP configuration, greatly simplifying configuration.
