Hey guys. Im thinking of installing a second router in our house to manage my own systems.

A little background on my situation, Im 19 and possibly moving out in the near future. Currently we have 1 router (WRT54 running tomato) that is hardwired to a single Comcast modem, my mothers office desktop and an xbox. In our basement, we have three desktops connected via wireless. Also, there are various phones and tablets that connect via wireless and a second xbox that is used every once and a while via wireless. My situation comes in with my two desktops (1 main desktop and a second desktop to backup files via FTP and to host a Digital Paintball server (half life, counterstrike type game) along with being able to use VNC inside and outside our local network.)

Id like to hardwire a second router in the basement and then hardwire my two desktops to that router. My main reason for this is so that my Server will be hardwired to prevent any lag that might happen with the wireless network. Also, having a router dedicated to my computers will allow me to make changes without effecting the rest of the family. Id like to just put the current router into the basement but My dad insists that my mom's work desktop be hardwired. Also, when I move out, Id like to already have my own network gear. Plus its kind of fun to figure this stuff out :) 


My plan - The main router is hardwired to the modem, and it's IP is 192.168.1.1. the second router would be attached via a 50ft cat6 (or cat 5e) cable and ran into the basement. My desktops would be wired to the second router. Now my questions, does FTP benefit from a 1000mb/s connection or is 100mb/s plenty? It seems like my ftp maxes out at 110mb/s through my crossover cable (hacked up straight through cable, I dont want to keep using this as my ftp solution. Wireless was way slow to backup large files quickly.) Also, how would my port forwarding for the server and desktop work? I have port forwarding setup for torrenting, vnc, and the Digital Paintball server. I can access vnc and the game server from the outside of my network. My first thoughts were that I would have the main router forward those ports to my second router's IP. Then have the second router forward those ports to the server/desktop? I feel like adding a second subnet might make things like this difficult.


This is a picture of what I have in my head. I know a second subnet/router is overkill for this work load but it is something id like to try out, I like exploring things.


sorry about the watermark. first time using that program.. free trial.

if both routers allow for gigabit connections then yes its a huge boost over 100mb. max speed your get over 100mb is about 10megabytes with overhead...with gigabyte its closer to 100megabytes.

I was hoping to get a second tomato compatible router.. i know the router we currently have is limited to 100mb/s. I assume that both my desktops are 1000mb/s capable and from what I understand cat5e is 1000mb/s ready.

well the problem is your limited to the bandwidth of the lesser router. from server/and desktop to the internet you still only get 100mb...now server to desktop...yes you get 1000mb but the second you go across that cat 5 you loss any benefits of that gigabit connection

Honestly, I think the only time I will need the 1000mb/s bandwidth is from my desktop to my server (both would be hardwired to the second router)

Our main router does not really do alot of heavy lifting.. I think our 20mb/s download 3mb/s upload would be the main bottleneck when it comes to getting access from outside our modem.

Nothing outside of my router will regularly need access to my server except for a laptop/android phone running a vnc client or my friends who connect to my DigialPaintball game and even 10mb/s is overkill for that.


So what Im getting at, a cat5e crossover cable will have higher speeds than a 100mb/s router/switch.. so 1000mb/s would be required if I want to maintain my current FTP transfer speeds?


What about my port forwarding? That is my main concern. I want to keep the server on the second subnet and still be able to forward vnc and digital paintball ports directly to it from the internet.

the cat5e cross over will not be higher than the 100mb...sorry. as for your port forwarding issue i don't think a second subnet would hurt you...though its a little work obviously.

Are you sure about cat5e? I know CAT 5 is limited to 100mb/s but cat5e is supposed to be 1000mb/s.. at least everywhere I look says it is.

the cable is yes but the router your connected to is not so it drops to the lower standard.

Well we dont know what router I will be using yet.. as I have not made that purchase. Like I said, I only really 'require' 1000mb/s on my own network (My desktop - My server, both on the same subnet)

I dont need that kind of bandwidth to go from the second router to the main router and into the internet.

My issue is being able to find a Tomato capable router that is 1000mb/s.

Mighty scary that you are going to load third party firmware on routers and you don't know how to find the list of compatible routers. many times you have to follow special instructions or you brick the router.

Not sure why you are using a router in the first place you should be able to use a switch. Makes the port forwarding much easier since you only need to do it one time.

As stated, I will taking the second router with me when I move out.. just makes sense. A router can act like a switch.


Ive been running tomato on this router for 3-4 years now, Im no stranger to it. Thanks for the list... Everytime I have searched "gigabit tomato router" or "1000mb/s tomato router" I have come up with nothing.

i was going by your little visual aid up top...the line between routers. one is gigabit one is not...therefore you drop to lower standard. now like i said before things only attached to the gigabit capable router will have a gigabit connection but only to other things attached to said router. you hope off it for anything you loss the benefits.
