One modem, two router, two networks - going crazy to figure it out

You know your post made me think.
Are you saying the cable connected to Router #1's LAN could respond differently when connected to a router than when connected to a laptop? It has juice on a laptop but the router isn't getting anything, it seems.

The cable connecting the two routers is 100' CAT7 https://www.amazon.com/gp/product/B084L6PHMM
that has been buried underground in a pvc pipe.
One end of it was accidently cut off and spliced back together.
After splicing it back together, I only get about 10mbps throughput even tough Router #1 puts out about 400mbps. But that's better than nothing. For me, it's fast enough to get stuff done.

I should point out this sharing of two routers USED TO WORK, although sometimes Router #2 would lose Internet connection, which I thought was due to IP conflict not cable problem.

Now, for some reason, I can't get anything of Router #2. But as I wrote cable does work when connected directly to laptop.

That definitely means it was rewired wrong. One of the pairs should be twisted if i recall correctly. Check a diagram and compare both ends.

The laptop may be able to negotiate the pin reconfiguration on its own, but the router may not.

Lantis, thank you so much for all your kind help. Until I get the chance to replace the cable, I am working on using Router #2 as wireless relay using this tutorial: https://www.gargoyle-router.com/wiki/do ... e_repeater

In this picture, https://www.gargoyle-router.com/wiki/li ... bridge.png the SSID TO BROADCAST is the same as the SSID of the AP Subnet router. Does it have to be the same or can I put in a different SSID? If so, then how do i set the encryption of the new SSID?

IF you prefer I post a new forum post on this topic, please let me know.

Encryption is inherited from the upstream link.

The simplest method to connect two modems is to turn ON the BRIDGE MODE on one of the modems. You can also do that by changing the IP setting. And if you only have a speed issue then use WiFi Extender.
