RJ45 Used to bypass router?

Hi!

I have 2 PCs in different rooms. I was wondering if connecting PC1 to a router then the RJ45 then back to the modem as well as PC 2 directly to the RJ45 would work... or if there is another solution I need. (See image)

Aside from the fact this would make cabling easier, my roommate needs to constantly reset the router (laptop keeps loosing connection for some reason) and I don't need the rest of the net to suddenly go down every time the router is being reset... thus bypassing the router on PC 2.

Try this link for the image if it's not showing:

I don't understand what your trying to do. I don't see the image.

If I understand this right you want to use one LAN connection for two computers? That won't work. I would try to do a TCP/IP stack reset on the laptop and/or update the WIFI driver or router's firmware. http://www.windows-secrets.co.uk/2013/08/repair-the-windows-87vista-tcpip-stack/

I don't think it's router's fault.... Well at least I've come to that conclusion. Every other wireless device seems to work asides from my roommates' laptop, which I've done some troubleshooting but still can't figure out. I've come to the conclusion that it's a physical problem.

*EDIT* I'll go ahead and try that. I also think there may be a PEBCAK error...but don't tell my roommate.

It won't work. The router and the desktop will be receiving the same IP address from the modem.
 
So, figuring the RJ wouldn't work I got a cheapo router from Craigslist and hooked it up this afternoon.
So far, so good. It's exactly as the picture, except I replaced the RJ45 with a router that has wireless disabled.
 
You still might have issues though. The new router has to be plugged in behind the original router and not actual plugged in from modem. It needs to go modem to router 1 to router 2. Router 1 hands out all internal IP addresses. For all intents and purposes, a regular 4 port switch would have worked here too. You need to disable dhcp on second router. Cable from lan port on router 1 to lan port on router 2. Internal IP address of router 2 should be 1 higher than router 1. For example. Router 1 internal IP is 192.168.1.1. Router 2 IP should be 192.168.1.2
 
To get that to work, you'd need a modem with multiple ethernet ports, you can't use a splitter. Or just buy a better router..
