I got a Ubuntu Server that run smb, transmission-daemon and DNS. In my home we are 9 people, with a total of 16 devices connected to the network.

List of "hardware"

  • 100Mbit line in
  • Standard modem from ISP
  • 2x N600 Wireless Dual Band Gigabit Router
  • Dumb gigabit switch (Not in use now)

Right now i have connected it like this: line in -> modem -> router -> router. In "prime time" we got some spikes on the network (this is on both cable and wlan). On a daily base we in total download/upload 22GB a day.

I was wondering if I can set up my server with two more network cards, and set up those as router, then my network would look like this:

line in -> modem -> Server router -> switch -> 2x router.

TLDR: How to set up Ubuntu server with 3 network cards, 1 for local server, 2 for Router.

I think the spikes comes from the poor router that is the connected to the modem.

The bottleneck of the ISP modem. You should only need one router. What is the ISP modem? (cable, ADSL2+, etc.) What is the '2x router'? (a brand/model, or two identical routers?) This should work just fine with: line in -> modem -> router (w/ dual-band WiFi) -> Gigabit switch -> server, other Ethernet devices –  david6 Oct 8 '12 at 5:04
    
I doubt it is the ISP modem, i get 100mbit with it. Like i wrote in the post, the wlan routers are: N600 Wireless Dual Band Gigabit Router. You can't meen that I should have 1 home wlan ap for 16 devices? –  Fyksen Oct 8 '12 at 10:44
    
No. I needed clarity that you meant two identical WiFi routers. You just need to disable one as router, and attach it to either the first router or Gigabit switch (based on whether there is a spare port on the first router). –  david6 Oct 9 '12 at 0:35
    
Its to identical wifi routers. The network is up and running now, but i get spikes. Like the post sais, I have connected one router to the other: line in-> modem-> router -> router –  Fyksen Oct 9 '12 at 9:09
