Should I be on different Channels for this WiFi network?

  • 772

I'm not sure if our 3 routers, in our wifi network, should be on separate channels (so each can maximize the bandwidth per channel) ?

Our office is networked via WiFi. It is in the shape of a 'L' and is made up of 4 rooms. In 3 of these rooms are 3 routers.

A: Billion BiPAC 7404VNPX. Internet Gateway. VOIP Device. (Firmware: 6.03)

B: Asus RT-N12 (firmware: 1008) Repeater Mode

C: Asus RT-N12 (firmware: 1008) Repeater Mode

 ___
[ A ]
[   ] ______
[ B ][     C]
 ---  ------

The reason why the 'C' device is over on the far end of the room is because we have a few devices that connect via ethernet to the back of that device.

That is the reason why I have 3 routers >> to extend the wifi from device 'A' all the way around the corner to the devices, at location 'C'. Otherwise, anything in room 'C' cannot see the wifi (too much interference).

Anyways, here's a scan of the WiFi network using inSSIDER 2.0.

This screen shot was taken on my MacBook pro a foot or so away from router 'B'.

Now, should I be placing each router on it's own channel? with the end of the each router range touching the next one?

EG.

  • Router A on channel 1.
  • Router B on channel 9.
  • Router C on channel 13.

    as Ignacio suggests, repeaters MUST be on the same frequency

    Repeaters are a nasty way to network an office As you probably already know, the (already slim) bandwidth is halved

    If you can spare the extra cash, install one more router beside Router B & connect them together via ethernet So, assuming device C only has wired devices connecting to it, set it up as a client-bridge as with the extra router....

    Router A (AP)

    Router B (CL)===Router B2 (AP)

    Router C (CL)

    This setup will give you full wireless bandwidth (depending on congestion) It will also allow you to seperate the frequencies

    Router A & B - Ch1 Router B2 & C - Ch9

    Wireless devices will be able to connect to Routers' A & B2 and there should be enough signal for all four rooms, otherwise you'll want a C2 :-)

  2. OK, without purchasing another router the only thing you can really do is run ethernet

    Either run the cable between A & B or B & C, whatever is most convenient and set them as AP or repeater depending on your needs

    But as Chris S said, taking out repeaters makes things far more reliable
