Hi to everybody!
I've a wifi net covering a big area. In this area i want to put some access point (OM1P mesh router ), let me say around 20 access points.
Every time a client connects an access point i retrieve its ip.
I absolute must know from that Ip, to which access point the client is connected!
I'm supposing to assign to every node, an ip range like:

Node A : Ip from 192.168.10 .1 >> 192.168.10 .254
Node B : Ip from 192.168.11 .1 >> 192.168.11 .254
Node C : Ip from 192.168.12 .1 >> 192.168.12 .254

Is it possible to do this with an OM1P mesh router?
"I hope I made myself clear..
Many thanks and excuse me for my english!

Ip ranges are based on decimal conversion of node mac addresses.

Alright. Assume a MAC address of 00:12:CF:12:3A:BC.

The node from the ad-hoc side has a fixed ip address of 5.18.58.188. If you look at the last 3 sections of the MAC address, and count them as base-16, the ip address matches the decimal value of the MAC (i.e. 12 base 16 = 18, 3A base 16 = 58, BC base 16 = 188).

This decimal conversion is used again in each node's client network, with 101.58.188.1 being the node's address and the clients in this range.

Make sense?

I've understood conversion, all right, but but but...
Every node in my net will have fixed ip, right?
When my client (mobile phone) will connect to the node, with some function (javascript, vb net) i'll get "client ip", and as a result I'll get the Node MAC.., right?
If through the client-ip i can get the MAC of the node, it's done!
I'm really an "absolute beginner"!

In my experience the nodes always resolve the same. So yes, the nodes will have predictable static IPs. But as for your question with the MAC... Each network device has its own MAC. Your phone will have its own MAC so it will not get the node's MAC. I don't know why you would want your phone to get the MAC of the node anyway. That would royally screw up the things "networkly" speaking. Network Address Translation (NAT) takes place at the node to allow a device to connect to the internet. Does this help? Smile

Imagine 20 access point under the same wifi net.
How can i know to which AP the client is connected?
Depending to that, i'll send different information to the client.
I can't install any software to the clients (mobile phones), so I can get net information only through the browser...
That wifi mobile is moving among my Ap and I don't know how to catch it!
This is making me crazy.
Thanks to everybody Guys.

OK... Here's what you need to do... If you haven't already, go checkout the wiki.

This will answer alot of questions forming in your head. Next get a number of routers at least 3 but I have found 5 to be best for tinkering. 5 allows you to play around with a number of different scenarios. Set up an network on a dashboard like open-mesh.com or cloudtrax.com. You will be able to see usage, radio, and networking data. At this point you will be able to tell if Robin is for you and your business scenario.

If you go to open-mesh decide to build a test nework, I recommend getting third party routers flashed with Robin to test with. One, you will get experience flashing routers which is invaluable, and two, if Robin is not for you, the routers can be flashed back to the manufacture's firmware and used in other projects or easily sold.

Just my two cents worth... Smile

Thanks jesterz, thanks ezyfi-sc.
If I'm not wrong I can do something with the redirect page, it can be any web page I like, that's mean i can personalize it even with variables.....

there is no guarentee though. once the node reboots it loses the arp table and it may give the client devices a new ip.


mchruch,

you can also look into things like coova and chilli coova if access control is what you are looking for.

Forgive me... Embarassed Maybe I was a bit unclear. When I was refering to static ip addresses, I was refering to the node itself not to any clients attached. It's anybody's guess what the ip address will be for the client (at least 1 of 253 possibilities). Smile

ah, ok. got ya. yes, the node radios, will resolve the same IPs each time. since they resolve based on MAC addess, as long as that deosn't change it will be the same Razz

Right! Splash page , captive portal and redirect that's one solution.
Every AP has its own splash page.
Surprised
