I have a wireless access point where they have 50+ wireless client and the connection just blow up in sometime. I think it related to overload on hardware.
So is there anyway to simulate or something like that to test wireless access point in heavy connection from many client, So I can manage to see what configuration is best for it.
I don't know about any tool but you can restrict number of clients accessing your router from router web page. You can do some hit and trial and see how many clients can access without router getting blown up.
You can use TMnetSim to simulate delay and package loss.

I was going through this PubNub WebRTC demo. https://kevingleason.me/SimpleRTC/minivid.html
Which works fine within same network (same browser or different devices across same network). But I tried using it over internet, I am able to connect a call but can not see anything but a black screen. This is the source for same tutorial
https://github.com/pubnub/SimpleRTC
I have gone through many such application, such as AndroidRTC
and I face same problem (black screen after connection over internet). I am unable to figure out why, any help is appreciated.
You need some sort of signaling mechanism (PubNub, Firebase, or your own software [nodejs seems the preferred choice these days]) to get the webRTC API communicating P2P on your local network. To get webRTC to work from one network to another you need a STUN server/service. Google provides free stun servers (stun:stun.l.google.com:19302). To get webRTC to traverse strict firewall settings and complicated networks you need a TURN server/service like xirsys.com.
This article covers it all ...

I'm looking for a way to set an external authentication server that will work on many/most wireless routers. Or , alternatively several ways that will work on different wireless routers. It needs to be done programmatically, meaning, that a computer connected to the router needs to be able to use some api maybe to do this.
I don't know if this is possible, I tried to find answers on Google, but with limited knowledge, I'm not sure that I'm even looking in the right place.
What I'm trying to achieve:
I'm trying to create an application that will allow people to open there WIFI so other people can borrow it.
The ide is:
To borrowed wifis:
Create an account with the application.
Log into the application. This app will, when you are logged in, automatically connect you to a wifi nearby that is shared. The share wifi will only be accessible if you have a valid username-password combo with the application
To share your wifi:
From the same application, you go into some menu and press "share this wifi", and somehow, I need this to configure the currently connected router to use the an external authentication server as well as the current WIFI key. So that, people can essentially use their the application username-password combo to log into this router.
Any help is appreciated.
Try google-ing for Radius Server , WPA(2) Enterprise , or 802.1x.
These keywords are very related.
To setup a radius authentication you need to have a router which supports wpa(2) enterprise and a radius server (probably google-able how to setup on windows/linux).
Programmatically connecting is possible, only a bit more difficult because it uses wpa(2) enterprise authentication.
If you could supply some more details i should be able to help you further.
I don't know if anybody have issued this, but I wan't to ask. My problem was like this:
I could use video chatting from apprtc.appspot.com using two Chrome tab (which means I call myself). Everything worked well.
I could use apprtc with two different laptop as well, if those laptop were on the same network. I used my university's network behind proxy.
However, apprtc didn't work if I used it with one laptop on modem, and the other on LAN.
Can anybody explain what happened? Is this STUN/ICE problem? Or JSEP?
The public demo includes a STUN server but does not provide a TURN sever because the bandwidth to run a free TURN server is expensive. STUN get thought lots but not all NATs / firewalls but not anywhere near as many as TURN. You might be in a situation where TURN would work (but you don't have a TURN server) but STUN does not.
I've been able to use the demo at http://apprtc.appspot.com/ from behind two different NAT's. So it can at least work in theory; but it's also fairly well known that STUN, TURN and ICE aren't infallible. For starters, if someone has blocked access to the port 19302 (the port of the STUN server that the apprtc demo uses), the firewall traversal will never be able to get started.
The basic troubleshooting step would be to open up the Chrome developer tools (ctrl-shift-i) and look to see if there are any errors in the console. Failing to observe anything interesting there, you'd need to write up your own version of the demo app, this time with better error handling. For instance, the apprtc demo assumes certain things that can't really be taken for granted, for instance, that peerConnection.setLocalDescripton() and peerConnection.setRemoteDescription() will succeed. In production code, you'd really need to implement both success and failure callbacks on those - and that would give you better information about what might be going wrong.
AppRTC uses stun by default. TURN is 'better' (from my understanding), but I recall Justin Uberti saying public TURN servers will likely be misused (or something to that effect).
STUN often fails on enterprise grade subnets because it can't 'cope' with unfriendly NAT addressing.
I writing a mac application and i need to discover other Macs/PCs/iPhones/iPads connected to the same WIFI network.
Bonjour seems to be the most reasonable choice, but it turned out that it has problems on many types of routers (on mine for example, is not working as it blocks Bonjour services).
I just need to find iPs of devices, then i will try to connect to an application-specific port to determine if my process is running there.
What is the best approach to accomplish this task, without violating the App store Sandboxing?
ARP was the first answer which came to my mind. Does your network-setup allows this?
I have a piece of software I have written that talks to a web service over it's Wifi connection on a Casio WinCE handheld.
Unfortunately the Wifi network and the network created by WMDC (or ActiveSync) to host the debugger connection clash, they are both 192.168.55.0/24. So I can't have them both connected at the same time.
Does anybody know if you can reconfigure WMDC to use a different address range?
I've hunted through the registry but can't see anything obvious, and Google is not turning up anything useful.
Thanks,
James.
Is the development PC on teh same network as the WiFi connection? If so, I'd abandon ActiveSync/WMDC altogetehr and just use ethernet debugging over the same connection that it's using for the web service calls.
