How to create a transparent AP with more than 1 wireless cards

I was in need of this transparent AP because I had a linux server and 2 transparent AP-s that clients use to connect to my network. I wanted to change the AP-s so that more bandwith can be provided for the clients. The clients configuration was something like this:

IP       = 10.100.11.x
netmask  = 255.255.255.0
gateway  = 10.100.11.1

I purchased a routerboard with 1 ethernet card and 2 wireless cards. Performing the routing, the configuration of my network had to change so that the wireless cards` IP-s would be the gateways for the clients. In this scenario I had to change the routing of the linux server in a way that the Mikrotik box would be the gateway for the clients. Beside this, we had to change half of the clients` IP because wlan1 became 10.100.11.1 and wlan2 was 10.100.12.1 (new network). People who connect on wlan2 need to be in the 10.100.12.x/24 range.

With a little help from the Mikrotik forum (thanks guys) I succedded in doing this:

eth1  = 10.100.13.1/24
wlan1 = 10.100.12.254/24
wlan2 = 10.100.11.254/24

Now, all 3 interfaces are in bridge and they forward traffic without any question to my Linux box . The wlan1 and wlan2 still have IP-s in that range accidentally, they can have any private IP address, it doesn`t matter anymore.

Here is what you have to do (everything in telnet console):

interface bridge add name=bridge1 (bridge1 being the name of the bridge, in lack of ideas)
interface bridge port add interface=ether1 bridge=bridge1
interface bridge port add interface=wlan1 bridge=bridge1
interface bridge port add interface=wlan2 bridge=bridge1

The wireless cards are in ap-bridge operating mode.

interface wireless set wlan1 mode=ap-bridge ssid=greaca1
interface wireless set wlan2 mode=ap-bridge ssid=greaca2

(Click for full-size image)

And now, we have this configuration:

Client IP 10.100.11.2 netmask 255.255.255.0 gateway 10.100.11.1 -> Mikrotik wlan1 (IP=10.100.12.254/24) -> linux server ip 10.100.11.1.

Here are the connected client APs, 28 on that moment.

The default gateway for the mikrotik box is 10.100.13.2, an IP alias on the same ethernet card in the linux server that is 10.100.11.1, but it doesn`t count... it can be any IP, doesn`t have to be in the same range with the linux server.

Here is the complete scheme of my network in that town:

I don`t know how many people it`s gonna help but it was a breakthrough for me and it helped me a lot.

I haven`t tried putting more than 2 wireless cards, but I`m pretty sure it will be fine.

Noob nanobridge m5 25m question(2)

Noob nanobridge m5 25m question

I am fresh to the group. I am fresh to continued ambit wireless internet links. I am a ham radio operator, and accept alot of acquaintance with antennas, and wireless packet radio. I am a abundant bartering adept electrician, with 30 years acquaintance with appealing acceptable computer skills.

I appetite to set up a articulation to get wireless articulation from a accompany home to a cabin.

I appetite to affix up to his bare 15mbps cable broadband modem, to my cabin.

I am on a arid abundance ridge, about 2000 anxiety aloft the valley, with a apple-pie band of afterimage attractive bottomward to the home, with projected roof location, with annihilation blocking link.

The ambit is 12km b line.

I ordered a set of nanobridge m5 25m, units. (2 units)

I appetite to affix the bowl to my home network, wrt54g wireless router.

Also up actuality is a neighbor, about 2.5to 3km away, about 500 ft beneath me, additionally with a apple-pie band of afterimage amid us, with no obstructions.

I appetite to affix both the acquaintance and myself together, at the breadth breadth my bowl is, pointing bottomward to the home in the valley.

My catechism is, ,will my articulation work, and how can I additionally breach my account with my neighbor. What will she need, what affectionate of antennas should we use amid my acquaintance and myself. Does she charge a nanobridge m5 22m set. Or is there article we can do to allotment my end dish. Her berth is about 15 to 20 degrees off to the left, and ten degrees bottomward from the continued aisle into the valley. Can we set up two nano bridges calm at the one backbone location, with an ethernet switch, and run a cat six from the about-face to my home to the wireless router.

Re: Noob nanobridge m5 25m question

You can do this with a Rocket M5, a baby 90 amount breadth at the breadth with the Internet uplink, and two Nanobridge M5 22dB antennas at the alien sites as CPEs.

15 to 20 degrees off arbor is too advanced for a point to multipoint nanobridge adjustment (between three nanobridges).

Take a attending at the RF adjustment (azimuth) apparent in the PDF datasheet, it's a awful directional product. The RF adjustment of a Nanobridge is abundant like a telescope. The added affair you'll appetite to verify is that you accept a bright fresnel breadth amid yourself and your neighbours.

Alternately you can use four nanobridge M5 units to articulation armpit A to B in a PTP arrangement, again addition brace to articulation from armpit B to C. Or if you don't appetite a sector, you could install two nanobridge units on your ridge, point one at anniversary abode you appetite to serve (separated by an azimuth aim of 20 degrees), and run anniversary in a altered 20MHz channel. If you could booty a aerial resolution google apple screenshot and draw curve on the map of what you appetite to affix it would be helpful.

If you accept a decidedly different or arduous project, able consulting casework are accessible in axial Asia, south Asia (AF, PK, IN, BD) and the Vancouver, BC area. Please acquaintance me for added details.

Re: Noob nanobridge m5 25m question

I'm cerebration you should accept a NanoStation M5 at your abode and the NanoBridges at your friend's and neighbor's place. Set your radio as an AP with applicant abreast off.

Re: Noob nanobridge m5 25m question

Confused.

You accept a 12km articulation from boondocks and you appetite to allotment it with your neighbor, correct?

A Google apple overview, a drawing, or annihilation like that would help.

Re: Noob nanobridge m5 25m question

If I accept it right, he's adage he's up on a backbone at 2000 ft acclivity aloft a valley. Internet is accessible 12km abroad in a boondocks somewhere. He wants to run a PTP articulation to that abode 12 km away, and he additionally wants a abstracted articulation to his acquaintance to allotment the connection.

It depends a lot on the azimuth angles complex whether a PtMP access would assignment best or two abstracted PTP bridges (using a absolute of four bowl blazon arch radios).

If you accept a decidedly different or arduous project, able consulting casework are accessible in axial Asia, south Asia (AF, PK, IN, BD) and the Vancouver, BC area. Please acquaintance me for added details.

M5 links.

Clarification.

My articulation to boondocks is 12 km. Bright band of sight, attractive bottomward on the home, with NOTHING abutting or in amid us. No trees, hills, barrio etc at all amid us.

Only I can see the boondocks source.

But I accept a bright shot, no obstuctions to both locations.

I appetite to get the internet articulation up actuality and allotment it with my neighbor.

My acquaintance will get her affiliation from me.

Can I aloof accompany both links calm with an ethernet switch.

And augment from that ethernet about-face to my abode router.

And what affectionate of radio/antenna do Charge at my place.

Can I accept aloof one antenna, at my location, for both links, or two complete sets of radios/dishes, abutting by an ethernet switch

NanoBridge questions - What is MIMO absolutely doing?

I had a ptp articulation with NanoBridge M2 to NanoBridge M2. I had abortion on one end and in a compression I configured a Bullet 2 (not M2) in its abode with a filigree dish(when you're fatigued on the abundance you try what you accept in the truck!). I had addition about-face off Airmax on the NanoBridge at the added end of the articulation and was able to get the articulation activity amid the Bullet 2 and the Nanobridge M2.

Everything is alive accomplished with this agreement while I'm cat-and-mouse for parts.

While ambience this up I came up with some questions:

- Is accepting a NanoBridge to NanoBridge articulation like accepting 4 radios, two on anniversary end with bifold polarity, like Rocket? I consistently anticipation thats what the MIMO allotment meant, appropriately the blue attractive feedhorn.

- I was alone able to affix the NanoBridge M2 to the Bullet 2 with Airmax disabled on the NanoBridge. How is Airmax accompanying to a Bifold Polarity agreement and/or MIMO?... Since you can get Bullets with Airmax, which are alone a distinct polarity, I'm confused.

- The airlink calculator on ubnt's web armpit says these two accessories are incompatible. Is that alone because the Bullet 2 doesn't abutment Airmax? I was able to get these two accessories to assignment aloof accomplished after Airmax.

Re: NanoBridge questions - What is MIMO absolutely doing?

Yes B2 does not accept airmax adequacy so the calc assuming incompitibility.

MIMO is accomplishing this as apparent in the absorbed file.

AirMax is polling...has annihilation to do with MIMO. It gives anniversary sta a time allotment to xmit so they aren't dispatch on eachother (hidden station).

rakpetel: I'm not bright on absolutely what the diagram means. Is that adage two TX and RX (4 radios) while additionally bold absolute amid two radios? Is the 4 radio config on 2 channels? Why is the MIMO AP alone able to set one channel??.. and not RX and TX channels configurable? Someone amuse clarify.

pawpaw: Thanks for the description on Airmax. I was bold thats why it said they were incompatible. I'm still abashed about if that relates in any way to MIMO... and if MIMO is absolutely a "dual polarity" configuration.

If the Nanostation is MIMO and the Bullet is not, how could they acquaint with anniversary other? I assumption it COULD be "failing over" to a bisected bifold on one channel.. but after compassionate how MIMO absolutely works, I'm not abiding I should accept that... and if MIMO absolutely is two channels active abounding duplex, why aren't these channels alone configurable?

I abhorrence to be a pain, but I appetite to absolutely accept whats activity on here

Re: NanoBridge questions - What is MIMO absolutely doing?

it doesn't accomplish faculty to me to address and accept on the aforementioned abundance at the aforementioned time.

With the MIMO alternation of AirMax radios, i.e. *not* Bullet or AirGrids, the assemblage has two radios that accomplish in accompany and on the aforementioned channel, and all radios are half-duplex, i.e. address again receive.

Should you appear to use a MIMO radio with a non-MIMO radio, i.e. Bullet or AirGrid, you alone use one of the chains and you don't get arrest from the added polarity alternation because you accept cross-polarization isolation.

You can still mix and bout AirMax and non-AirMax radios. You aloof accept to accomplish abiding to use 20 MHz approach amplitude and about-face of AirMax affection on the AP (the CPE automatically senses if AirMax is active or not).

Re: NanoBridge questions - What is MIMO absolutely doing?

There is alone one radio but there are 2 achievement chains to drive both V/H antenna polarities.... Both are on the aforementioned approach centre/width but are abandoned by the antenna polarities.

The apriorism is that the RF behaviour (Reflections/interference/penetration characteristics) are abundantly altered amid H/V polarities as to admittance the radios to balance added abstracts from the entering signals back accumulated at the receiver. This permits added abstracts to breeze per assemblage of Tx time

Single pol works as the receiver aloof doesn't see abundant if any arresting on one antenna alternation so all the abstracts is recovered from the one alternation which is why the abstracts tranfer amount is additionally halved..

In absolute activity the behaviour is still accountable to the aforementioned influences one would apprehend so you about accept a beneath than absolute articulation but for the best allotment the aloft applies..

There are algorithms complex in MIMO technology that acquiesce distinct approach use and accompanying xmit. In accession the UBNT radios use polarity to abstracted chains.
