I am not finding this question in SF history, which was a surprise, so I'll go ahead and ask it.
I am working on an IoT Raspberry Pi project with Windows 10 and need to connect it to the internet via an Ethernet/USB adapter. The adapter itself is made by Belkin. Using this, I can see an ip of 169.stuff get generated for my Pi, which is a private ip. I can deploy code to that from my connected box, however other devices are not able to reach it, and it is not able to make connections out to any servers.
I'm wondering if anybody knows how to bridge the connection.
I am attempting to use the new Azure IoT Hub and the SDK with this in case that makes any differences as that is not a simple rest interface and I believe is some form of socket connection.
Additional Notes:
I have installed a DCHP Server and the Pi gets the ip address: 192.168.0.3 assigned to it. Unfortunately the Pi still can not ping external sites, such as google.com
Latest Discoveries:
I am on a corporate box, which has internet sharing disabled by the system admin. Following these instructions: http://zizhujy.com/blog/post/2013/07/07/Solved-Internet-Connection-Sharing-has-been-disabled-by-the-Network-Administrator.aspx Fails. It shuts down all connectivity to my box and I cannot ping anything or reach the internet or anything.
Thanks,

The 169 address means it isn’t getting a DHCP address assigned.
Since you don't have a router for the Ethernet, you can use Internet Connection Sharing, however we will need to run the following commands against the Pi to set a static IP, gateway, and dns server, since internet connection sharing botches this up a bit at times:
Set-Item WSMan:\localhost\Client\TrustedHosts -Value 192.168.137.2
Enter-PSSession -ComputerName 192.168.137.2 -Credential 192.168.137.2\Administrator
set-executionpolicy unrestricted
netsh int ip set address "Ethernet" static 192.168.137.2 255.255.255.0 192.168.137.1
netsh int ip set dns "Ethernet" static 8.8.8.8
netsh interface ipv4 show config
set-executionpolicy remotesigned
You may need to reboot the Pi at this point then test pinging 8.8.8.8 and google.com to make sure resolution is working. You should be all set!
One other thing, if you have a group policy on the machine that is restricting Internet Connection Sharing then take a look at this article to fix the issue. Note if your organization is constantly sending down the policy then you may have to re-enable Internet Connection Sharing often which is aggravating but at least it will work.

I do this by creating a DHCP server on my laptop and connecting the Pi directly to it. I followed these instructions to get it working:
Download DHCP Server for Windows. It is a 100kB download.
Go to the IPv4 properties page of the Ethernet adapter and set a fixed IP address, say 192.168.2.1
Run the DHCP Server Wizard (downloaded above)
Select the Ethernet adapter from the list shown
Save the configuration file and start up the DHCP Server
Click the 'Continue as tray app' button in the server control panel.
Boot up the Raspberry Pi
A popup notification shows the IP address assigned by the DHCP server to the Raspberry Pi.
Use a SSH client, like PuTTy, to connect to the IP address shown
Hope this works!

I'm very unfamiliar with Linux so forgive me if this has been answered before, I've read quite a few answers but I'm never sure if they actually relate to my question.
I have a headless raspberry pi that connects to my phone's bluetooth automatically, my phone shares its internet access by tethering. I use this initial and reliable connection to SSH to my raspberry pi, and use the desktop with VNC viewer.
I would like to connect to a WiFi network that uses a captive portal, but the browser always uses the bluetooth connection so it never redirects me to the portal page. The bluetooth connection is just to be able to use the desktop so I can get through the portal, then I would like to either disconnect bluetooth or just not use it, mainly because of the low bandwidth it provides.
I've added wlan0 as a priority interface with ifmetric, but that hasn't worked.
I was thinking that forcing all HTTP connections through the wlan0 interface could solve the problem, but there may be a simpler way, feel free to tell me.
Can you explain in "simple" terms the best way to achieve this ?
Of course, there are multiple solutions. The simplest is making sure that there is only one correct default route.
There are 3 situations:
You are only connected via bluetooth via ssh
You are connected via bluetooth and via wifi, but not yet through the splash
You are through the splash
Each will require a different network configuration.
In 1, your network config will probably be:
some IP address (let's call it IP-bt) and network mask
Default gateway is your phone
With route -n you can verify this.
In 2, the network config will depend a bit on the wifi network, but in general, your network config will be:
you'll still have IP-bt
you will have a new address on the wifi adapter (which we call IP-wifi)
the default gateway should be the gateway on the wifi network.
When you verify this with route -n, you might still see a route with destination 0.0.0.0 towards your phone. You can delete this route. Your phone should be on a directly connected network and your ssh session should therefore not break.
If the default gw is not on the wifi network, you can still remove the route that sets your phone as default gw.
Under 3, the default gw must be on the wifi network, and not on the phone. You will still be able to use your phone, because it is directly connected.
Something to watch out for in this scenario is that your phone will act as a DHCP server. That means once in a while your DHCP lease will refresh, and the bluetooth default route may re-appear. Disconnecting bluetooth will prevent this.
The second solution is to use ifmetric. Instead of making wlan0 a lower metric, make your bluetooth a higher metric. Again verify with route -n that the metrics are as you want them to be. Verify with a traceroute how the packets are moving.
A third, and most complex option would be to install Quagga and configure correct routing.
I am facing an unknown problem in my laptop. i AM Using a router. From same router I connect my another PC and mobiles using same Wi-Fi. But my laptop not found internet. I have to use Manual DNS 4.2.2.1 . If I use this DNS then I can access internet. But all other my device and PC connect internet without problem. how to solve my Laptop problem. I am am using windows 8.1
Did you try to connect by Ethernet the notebook to the router?, to discard an OS problem.
The other option that you can try is deleting the WiFi config of that network.
Check if you have dhcp activated and check in your notebook if the ip is checked in automatic. Could happen that if you have manual ip, your dhcp is not in the range of your ip
DNS Doesn't connect you to the internet.
DNS Explained
It's possible you disabled DHCP in your router :P
You won't get a IP if that's the case
Please go to CMD.exe and type
ipconfig /all
Please post the following information:
DHCP Enabled
IPv4 Address
Subnet Mask
Default Gateway
DHCP Server
DNS Servers
Easy fix: Press the reset button on your router
If Only your Laptop faces this problem disable STATIC IP
Explained
Right click your network adapter
Choose "Change adapter settings"
Richt click your connected network adapter
Select "Properties"
Click on "Internet Protocol Version 4 (TCP/IPv4)
Choose Properties
Select "Obtain an IP address automatically"
Select "Obtain DNS Server address automatically"
Click "OK" then "Close"
Done.
I am trying to create a hotspot from my del laptop (windows 8.1).
I enter the following in the cmd prompt:
netsh wlan set hostednetwork mode=allow ssid=Hotspot key=Password
netsh wlan start hostednetwork
Till here everything is going well. Now when I try to share my broadband connection to the Hotspot connection, I repetedly get an error message"Cannot enable shared access error 1061 - the service cannot accept control at this time".
Can somebody please help me around with this issue?
I downloaded Virtual WiFi Router and was able to activate hotspot. After that even when I deleted the Virtual WiFi Router and used the above step to establish the hotspot, it worked.
I want to create an IIS server on my PC. I've created a wifi hotspot through netsh wlan set hostednetwork ... , and a new wifi hotspot appeared (wifi2, in which my pc was 192.168.137.1).
So I shared the connection of wifi1 (the real NIC, with ip 192.168.0.104) and I enabled sharing of HTTP service (because of the IIS server). Obviously IIS is running. wifi2 is set as a domestic net.
So, I've connected my smartphone to wifi2, and typed 192.168.137.1, the IP of my pc in wifi2, in wich it should be running the IIS server. But it respond with a timeout error. So I've typed 192.168.0.104 , the IP of wifi1, and I though my smartphone cannot reach it, because my phone is connected to wifi2, but it show the IIS home page. This is strange, but the problem is here: if I disconnect my PC from wifi1 (so there isn't an internet connection, but only a local wifi lan), from my smartphone I can't visualize anything, both 192.168.137.1 and 192.168.0.104 !
why I need an internet connection to show the IIS page?
How can I fix this problem?
I have my beaglebone black running stock Angstrom Linux and is connected to ethernet at my home. I can login from any PC connected to my home network using SSH. I would like to know how can I login from another network, say I am at my office and I am connected to internet. I want to login into my beaglebone black which is connected to internet at my Home. How can I do this?
Thanks in Advance
You have a public IP address, that is given to you by your Internet operator. This public IP however will be different than the IP of your Beagle in your local network.
To login to your Beagle from the Internet, you need to connect to your public IP address, and need to add port forwarding to your router, so that port 22, which is the socket port that is used by ssh, is forwarded from your public IP to your local IP.
So, you need to login to your router management console, and go to "port forwarding" options, and select to forward TCP/IP connections to port 22 be forwarded to your Beagle IP. For this to work longer term, you should set static IP address to your Beagle, otherwise if your board stays offline for long time, the DHCP server on your router will probably assign different IP at some point, and the forwarding would need to be setup again.
There is a good guide on the static IP address setting in Beagle/Angstrom here: http://derekmolloy.ie/set-ip-address-to-be-static-on-the-beaglebone-black/
One more thing: Since your operator will also assign different public IP for you from time to time, you might want to have some kind of Dynamic DNS service in use. With this kind of service, you can create your "custom" DNS address (for example user3180454.no-ip.com), that will always point to your Public IP address to which you can create ssh connection (the service will require some method to keep this IP address up to date, you will see instructions on how to do it from the service you use).
Couple services like this:
http://no-ip.com/
http://freedns.afraid.org/
You might also want to try out the Weaved connection service installer for BeagleBone Black. I'm using it to connect:
SSH on port 22
BBB web server on port 80
tightVNC server on port 5901
Shell in a Box on port 4200
Apache web server on port 8080
See:

If you are:
Connecting to from a BeagleBoard via USB Ethernet
from Mac Air running Mavericks & connected to web via Wifi
I found this very helpful:

In short >> install/run a proxy server (with Squidman) & your life will be easier.
I know this is an old question. But I thought I'd suggest another option. I use TeamViewer (https://www.teamviewer.com) to connect to my work/home computers. You could use something like this to connect to your home computer from the office. Once connected to your home computer, you could then do whatever you need to do on your home network. No port forwarding required.
