I'm connecting my Arduino Yún to my laptop via USB cable and as I read in Arduino documentation:
When you first power on the Yún, it will create a WiFi network called
ArduinoYun-XXXXXXXXXXXX. Connect your computer to this network.
But in my case nothing appears and I didn't found anything related to this on the web.
I'm running Windows 8.1 on my laptop.
Any idea how I can solve this problem?
It sounds as if something is wrong with the wifi configuration on the Yún. Has it previously been configured? Try resetting the wifi by pressing the "Wifi RST" button for more than five seconds (but less than 30).
More info here.
The question you asked is already answered by #mellbratt. You have successfully configured Yun and connected it to the network (configuration of WiFi by providing SSID and security key in web panel). The thing you have to do now, is to find what IP your Yun device is assigned on that network. You can use tools like Angry IP Scanner to scan the network and find your IP if you cannot access it from myusername.local. Using that IP you can access the web panel.

I setup my raspberry pi with a wifi connection (from a wifi extender), and had no issues. I could connect to the internet, everything was great.
I then changed my wifi extender, so went to my raspberry pi and logged into the new wireless. It says its connected to the wireless, but I can no longer connect to the internet or the network. Any thoughts?? When I switch back to my original wifi connection / extender, it works fine again.
Thanks
EDIT: This seems to be related to this!

In my opinion, I honestly dislike wireless. You could always get a Ethernet cable and plug it in, and it'll never do the error again. You can find them very cheap, and it's faster than wireless.
But, for some friendly Raspberry Pi reference, if you have another computer (it doesn't matter how old or slow, it'll work either way), you can download VNC Viewer, plug in your Ethernet cable to your Raspberry Pi (or you can use a WiFi adapter too!!), then find your Raspberry Pi's IP address, and use VNC Viewer to control your Raspberry Pi from that other computer. That's what I'm doing.
I hope I help with this :)
I have gone through several links online but I have not found any appropriate solution to it. I am wondering if there is a way to connect an Arduino with WiFi without using any shield or any other external hardware. My laptop is connected to WiFi and the arduino board is connected to the laptop with an USB cable. I want to access/run the data for the Arduino using WiFi. Is there a way to do it?
Hope my query makes a sense.
Thanks.
Let's restate your question for clarity - you want to share the laptop's Internet connection (e.g. via WiFi) with the Arduino connected to the laptop with a USB cable, with no additional hardware?
Assuming I restated it correctly, the Arduino's USB connection provides a virtual "serial port" for communication. This means you can use an "IP over serial" solution for Internet access. One such common and widely supported solution is PPP.
However, programing the Arduino with IP over PPP stack requires significant amount of memory and is probably an overkill for whatever it is you're trying to do.
You're probably better off designing a custom-tailored protocol for the serial communication between the Arduino and a small gateway program you can program and run on the laptop.
If you're bent on a complex solution that provides full Internet access to the Arduino, the steps to achieve what you're after are:
Program the Arduino with a TCP/IP over PPP protocol stack, running on the serial port. You'll probably need an Arduino MEGA.
Setup the laptop to be a PPP endpoint on the Arduino's serial port. For a Windows machine you can refer to this page for information on how to do that.
Once the PPP link is up, you can setup the laptop's OS to share Internet access to the PPP link.
I just got an arduino yun shield by dragino.
I plugged into my computer usb with an Arduino uno following the instructions of the wiki and powering it from 5v > vin.
After a while the wifi network popped up, so I entered it.
Went to http://192.168.240.1/ where I found the website / settings panel and added a password and connected to my own wifi network.
Now I have no idea how to get back to that website, what ip adress to use, or even how to reset those settings so it makes its own wifi network.
I can connect to the Arduino yun through the Arduino program, but I got this error after just trying to do a blinking light. It does not show me the IP for it.
I have also tried connecting it to the wall outlet but it didn't create a network.
Is there anyway to completely reset the board?
It seems as if the shield was set to connect to your WiFi which in turn was set to get an IP address from your WiFi Router. If you want to find out what IP Address was assigned to the shield by the WiFi Router then you can go about it in two ways:
Log onto your WiFi Router and see if it contains a DHCP clients
list. If the shield was assigned an IP from that router then it will be in that list as well.
Use software like SoftPerfect Network Scanner (https://www.softperfect.com/products/networkscanner/) to scan for all hosts on your network. You can then see which IPs were assigned to the hosts. One of them will most probably be the shield.
According to the shield's user manual you can reset to factory settings:
5.7 How to reset the Yun Shield? Yun Shield has a toggle button which can be used for reset. When the system of Yun Shield is
running, user can press the toggle button to reset the device. If
pressing the toggle button and release after 5 seconds , it will
reset the WiFi setting and other settings will be kept. If
pressing the toggle button and release after 30 second s , it will
reset ALL the setting to factory default.
There are many options.
If you haven't changed the name of your Yun it's likely to have the default hostname: arduino.local, therefore, if the device has connected properly, you should be able to access it in the browser as http://arduino.local
This should work on OSX. On Windows you will need to use the Bonjour Service for this (which should come with iTunes for Windows). On Linux you can use avahi.
Another option is to ask your Yun what it's IP address is using an Arduino sketch and the USB cable. You can find some handy examples in Arduino > File > Examples > Bridge
I recommend checking out sketches like :
WiFiStatus
YunSerialTerminal
ShellCommands
Either of these should allow you to get see useful info in Serial Monitor.
For example, if you send the ifconfig command via Serial Monitor.
Also, as Blurry Sterk already mentioned, you have the WiFi reset button which can reset the Wifi settings to default. By the way, with the default settings, the WiFi Access Point network name is
Arduino Yun-XXXXXXXXXXXX", where the twelve 'X' are the MAC address of your Yún
(according to the Arduino docs).
write it down (or at least the first 3 parts). You can see devices on your network along with the mac addresses using the arp command.
On Windows:
arp -a
On OSX:
arp -a -x -l
You can find the Yun's mac address in the list, and the IP from there.
Hi i'm trying to access my wifi shield's ip address on the browser but I keep getting Oops! Google Chrome could not connect to "IP ADDRESS".
Things I've done:
1.)Updated firmware on wifi shield using this link http://ohmyfarads.com/2013/11/11/updating-firmware-on-arduino-wifi-shield-for-dummies/
2.) uploaded the wifi WPA sketch from arduino site. My connection is WPA2
3.) I switched between arduino IDE 1.02 and 1.05 but no luck with either
4.) I'm using an arduino uno board that is attached to wifi shield
Help? Thanks!
This might be caused by incorrect router setup. Things you should look at:
1.You may have to first add device mac address to router list and assign it to the specific IP address you want to have.
2.The second option is that router may give his own address to this device by DHCP.
Remember that you have to choose nonroutable IP address for your shield. IP also has to be in your home address range. The simplest way to check that is:
1.Manu Start
2.Launch and type (or type in search) cmd
3.In console type "ipconfig"
Your local IP is in IPv4 .......... 192.168.x.x (most likely)
(in this case shield should have address like (192.168.x.y).
For more information about IP [look here][1]
You can also use Netscan tool to find out if shield is in your LAN.
I hope it will be helpful.
I have an Arduino UNO and a 3G shield ( http://imall.iteadstudio.com/development-platform/arduino/im121026002.html ). To connect to the internet I had only to configure the APN once which the SIM provider gave me and write the PIN number via AT commands in the setup() function, that's all.
I have some questions:
1) the internet key which the SIM belongs to comes with a software you have to use to connect to the internet: each time you want to connect you press CONNECT and when you are finished you press DISCONNECT. The 3G shield on the contrary needs only APN and PIN and that's it: am I forgetting anything? The module works, therfore I don't think so: what's your experience?
2) the internet key software needs to be configured with a "Dial Number" too, which I don't know what's for. The 3G shield works without any "Dial Number": any idea why?
3) sometimes while surfing the internet with the internet key, you loose the connection (maybe the provider kicks you off). In that case you have to click connect and you are in again. If something like that happens with Arduino+3G what do I have to do? I tried resetting the 3G module via the reset pin, but the module cannot register any more into the network.
Thank you in advance
1.) It sounds as though the 3G shield is set up to automatically connect to the internet when it is powered on, and the setup function does this.
Depending upon the design of the software supplied with your internet key, you may be able to configure it to do the same thing, so that you wouldn't have to press Connect/Disconnect each time.
2.) The 3G shield probably uses a default dial number like 99**1#.
3.)If the connection is lost due to external factors, e.g. the network dropping the connection, then the 3G shield probably tries to re-connect automatically. If the connection is lost because of a problem in the shield, then powering it off and on again will probably do the trick, but you will have to enter the PIN again of course.
At a guess, the reset button may lock the SIM again, and that's why it appears to lose the network. It sounds as though you would have to run the setup function again, to unlock the SIM and connect to the network.
