Is there a way to access the signal info of the devices that are attached to a wireless router? I was thinking that maybe that information is given in the router homepage, but my netgear router only gives me the IP and MAC addresses of the attached devices. Also, in case that this isn't possible with my router (DGN2000), are you aware of another device that gives that kind of information (even if it needs custom firmware to display it).
I want to make an app that collects the attached device signal data and I am stuck.
So I found the solution. Any router that can run on dd wrt firmware can access that data by navigating to "status" and then "wireless" in the router page. Another (and expensive) solution is the Apple Airport router, that gives that data via the airport utility.

In short i'm trying to build an App that will grant/block wifi access to my son's wifi for his Ipad and his PS4 remotely using an App. I researched the topic and can't figure out how this can be done. Ideally i'd like to be able to grant/block wifi access independently Ie. block wifi to the Ipad and allow PS4.
How can this be done, no need for the full code ( well if you insist i'll take it ) but just point me in the right direction.
Depending on the router you're using you're going to need to write something that interacts with the router's API, if it has one. If it doesn't, you will need to replace the firmware on your router with something like ddwrt that can be scripted. From there, you might be able to create an app that talks to the router's API.
TLDR: You're probably better off simply bookmarking the management page for the router and enabling/disabling access for the devices.
Edit:
It occurred to me that some mainstream consumer router/access point manufacturers (Linksys, Asus, etc) have companion apps for managing their devices from the LAN side. You should see if such an app exists for your router, and if not, perhaps consider getting a different router that supports such an app.
I did a lot of brain-storming about this, and couldn't reach a solution.
I am posting this as i can get some ideas.
I have developed a WiFi-IoT based device with sensor, which shows up in AP mode. A mobile phone connects to this AP and then the device starts sending sensor data to the mobile phone. A mobile application plots and displays this data.
Now, i want to send this data from mobile to internet. Connecting my mobile to another AP with internet is not an option, as i don't want to break the continuous data transmission.
Using internet of data provider is one option, but that brings constraint of have mobile data.
What other options do i have to send my data from mobile to internet ??
Edit:-
I worked on the suggestions, and came to this point:-
1) WiFi-IoT device (in station mode) and mobile phone connect to same Internet-enabled WiFi access point. WiFi-IoT device has the IP address of the mobile phone for current network, and sends data to a TCP port (eg. 9801) of this IP address. The application in mobile phone reads the data from the port no. 9801 and stores it and hosts it on the internet.
This works fine.
2)WiFi-IoT device comes up in Access Point mode, and the mobile phone connects to this Access Point. Now there is one-to-one connection between WiFi-IoT device and mobile phone.
My question is, in the second scenario, without breaking this one-to-one connection, is there way to host data to internet:-
1) without using mobile internet provided by mobile data service provider ?
2) without using a second mobile phone ?
I may be wrong, but i am just asking this to make be sure whether my requirement can be achieved or not !!
I don't think you can connect to two APs at the same time.
Maybe use Bluetooth as device to phone link?
Or have the device connect directly to internet after some config done in AP mode and then send a copy of the data to your phone app (either via WAN or locally to the private IP your phone gets from the Internet gateway AP)?
--Edit--
Let me explain about the second one:
What I mean is basically have your IoT device directly connect to Internet and send data to a server (your phone has also to be connected to Internet). Then make the server send a data copy back to your phone. It's two step process: 1) while the IoT device is in AP mode, use your phone to login and configure which Internet-connected AP it should be connected to. This serves as UI for your IoT device. 2) start sending data.
Or a bit ugly, just let the IoT device talk to your phone in the same WiFi network via private IP.
I brought up this way because you mentioned anyway your device has to send data to Internet(I assume it's a server) and have phone talk to a known location server is more portable and scalable once you have more than one IoT device.
--Further Edit--
I don't think there is a way to do what you described. At least from my experience:
1) on the link layer, the wireless NIC has to be able to connect to two APs at the same time. This is not a feature currently available.
2) on the network layer, there has to be two IP address attached to the same NIC, which I don't think is available in current OS for wireless NICs. Though there is a way to do this for Ethernet card, I.e. via Aliasing.
How can I programtically get the MAC address of WiFi router.
i want the command or the program in c which will list only the mac address of devices which are connected to the my WiFi router. it it possible to get when i know the IP address of the router?
Getting the MAC of the WiFi router on which you are connected (or try to connect) is probably possible if you have access to low level network frame.
Now it looks you are indeed willing to get the MAC of ALL the devices connected to the WiFi router, which is another thing ! Unless the router has some building functionality that gives you this list (like an HTML summary, I don't know if openWrt provide this), I don't think by running a program in C on a client, you would be able to get the MACs of other connected clients !
But in case the router as the information in an html page (eg : from a remote administration), you might try to simulate login to administration, get this page then parse the page to get the MACs... from a C prog..
Taking your problem from another side, if you have a wireless adapter you can set in monitor mode, you could sniff the wireless traffic on the channel(s) opened by your targeted WiFi router, and list the distinct client connected. Have a look to BackTrack's ssidsniff ?
I want to know if there is any iOS API available which can be used to find out what kind of router i am connected to.. for Ex:- if wifi router is a G type router or N type router.
My application have needs to identify the kind of router connected & based on that start proceeding to the next steps.
Any help will be appreciated.
I don't think that sort of info is send over a WiFi signal. Unless you hack into the router and pull its details.
Can you not just check the speed and determine N/G etc based on that?
Did you see this thread,
Accessing iPhone WiFi Information via SDK
Iy mentions few external private API's to get Wifi information , have a look
Use Case:
We have an iOS application where you can run a network test between an iOS device and its associated wireless access point to test throughput. The app can get the IP address of the iOS device just fine, but the user has to type in the IP of the access point.
Problem:
The task is to get the IP address of the associated access point, and pre fill it for the user, hence avoiding user intervention there.
My Approach:
Find out the Mac Address/BSSID of the access point.
I do this by employing the Captive Network API.
Issue an ARP request to find out the IP associated to the access point.
I haven't been able to accomplish this as of yet. Google and SO search has kind of lead me to a dead end here. Here are some similar questions:
How do I query the ARP table on iPhone? AND
ARP Requests on iPhone
Question:
What is the right way to do this? In fewer words, what is the best way to get the IP address of the access point an iOS device is connected to.
A WiFi access point is not necessarily an IP-capable device (although many of them are, but for configuration, not communications, purposes).
Even if you do get the actual access point's IP address, how are you going to test the throughput? You could send ICMP Echo requests, but that will just give you instantaneous round-trip times, not throughput, and many IP devices, for security reasons, are configured to not respond to ICMP ECHO requests.
BSSID is unique for each SSID on each Radio and it differs from the Access Point’s Mac Address. If you compare them you can see last characters of Mac Adresses are different for BSSID and the AccessPoint.
