Mwan3 - multiple wireless STA as Interfaces

Hi every body,

Is it possible to have multiple STA (wireless) with same radio hardware ?
(i'm aware that radio frame can't be possible at the same time)

I want to connect 3 devices, each can provide ~100kb/S. I want to merge together in 300kb/s ( for bit torrent only, i'm confortable with HTTPS limitations).

I try to do this :

  • 3 wireless Network, attach on 3 different WAN interface and then use mwan3 ?
    I'm right ?

Thanks for your help

iw phy0 info | grep 'valid interface combinations' -A 3

(And if so, both upstream APs would likely have to be on the same channel...that's indicated by the #channels <= x value.)

Hi thanks for your fast reply. Good way :slight_smile:
That's my output :

valid interface combinations:
		 * #{ managed } <= 2048, #{ AP, mesh point } <= 8, #{ P2P-client, P2P-GO } <= 1, #{ IBSS } <= 1,
		   total <= 2048, #channels <= 1, STA/AP BI must match, radar detect widths: { 20 MHz (no HT), 20 MHz, 40 MHz }

If i understand, with this interface i can doing

  • 8 AP simultaneous
  • only 1 STA at the same time ?

I don't want running this "exactly" simultaneous, but very fast, one after one ?
Do you understand what i try to explain ? (sorry for my poor english)

:confused:

It sounds like you're describing a non-existent mode.


I can connect 2 Wireless network to the same acces point, simultaneous

I don't understand with your previous message, i suppose to be connected only once ??!

I will try to describe what I want to do.

I have the possibility of connecting to 3 access points, which each deliver an internet connection with a speed of around 100 kb / s.

I have at my disposal a router under openwrt (TL-WR1043ND). It has only one radio.

I want to connect to each access point "simultaneously", and use mwan3 to "merge" the internet connections and thus obtain a speed of 300kb / s. I am fully aware of the constraints linked to web requests (https in particular, which cannot be "loadbalanced" natively). But for protocols that establish independent parallel links, this can work.

Is it clearer?

PS: I have been using openwrt for years, but a rather classic use with some small ash hacks. Rather comfortable under Linux, but not too much in networks ...

It should work, though you will need to configure the access points to all operate on the same channel.

Also it will be a lot easier to make work if the access point IPs (your gateway route to the Internet) are all in different subnets.

Yes, all access points are on the same channel. But I don't understand how to do load balancing, and the allocation of interfaces / firewall. For this case.

Also it will be a lot easier to make work if the access point IPs (your gateway route to the Internet) are all in different subnets.

The ip address is dynamically assigned by the access points (by the access provider). The clients are isolated from each other, but it is possible that the IPs are on the same subnet (to verify, but it is dynamic)

Do you get a RFC1918 (private) IP from the access point or a public IP?

Separate public IPs would be no problem and that is how mwan3 is usually run. In the other case where maybe they are little hotspot/routers, if they all are (for example) 192.168.1.0/24 IPs with the AP itself being 192.168.1.1, it is going to be difficult to make separate networks for them.

I just tried to get IP addresses from the access points.

I get, for example: 10.135.153.188 and 10.135.167.249. For me, these IP addresses are of private type. But I don't know if this is a problem for what you mentioned in relation to wman3?

What is the subnet mask?

The subnet is /15
10.135.153.188/15

If the subnet mask is 255.254.0.0 (/15)

With mask /15 it won't work, because both 10.135.153.188/15 and 10.135.167.249/15 belong to the same network.

were you able to make multiple wireless connections work on the same radio?
