Cannot connect Windows Phone Emulator to Internet when using Wireless adapter on the host - windows-phone-7

I’m developing Windows Phone app using VS2012 on Dell XPS 15 laptop with Win8 pro.I read a lot of troubleshooting articles here (specially Windows Phone 8 emulator can't connect to the internet) and in other places on the web and have not managed to solve the issue (see the subject). Note my laptop gets successfully IP using DHCP on both adapters (wireless and wired) and no MAC filtering is set on the router. Here is the story:
1) Does not work: When starting WP emulator, it does not get IP from
router (DHCP)
2) Works:
start over (delete virtual switches and machine in Hyper-v)
disable wireless adapter
connect wired adapter to router with cable
start emulator (it creates machine and switches)
gets IP and Internet is accessible
3) Does not work:
start over (delete virtual switches and machine in Hyper-v)
disable wired adapter– windows control panel shows : Bluetooth and
Wireless enabled and wired disable – no others
start emulator (it creates machine and switches)
result:
a) router log shows “DHCP server received REQUEST”
b) on the host I see (ipconfig) virtual switch gets IP (vEthernet
(Intel(R) Centrino(R) Wireless-N 1030 Virtual Switch)) – it selected
as “Windows Phone Emulator External” in virtual machine settings
c) in emulator network tab of “Additional Tools” window I see adaptors
with default IP 169.*
3) Partially works:
delete virtual switches
disable wired adapter– windows control panel shows : Bluetooth and
Wireless enabled and wired disable – no others
create internal switch in hyper-v named “Windows Phone Emulator
Internal Switch” and select it in internal network adapter of virtual
machine
enable sharing in wireless adapter (in control panel)
start emulator as standalone with xde.exe (starting from VS will not
use right snapshot with deployed app) and does not allow it to
connect to network – loading takes much more time and after that, OS
is loading and emulator shows error dialog “Some functionality maybe
disables”
it possible to use emulator with Internet, but device buttons does
not work – use keyboard shortcuts
(http://devatheart.azurewebsites.net/2011/06/04/windows-phone-7-emulator-and-physical-keyboard-shortcuts/)
it cannot be used for debugging – it is good only for showing the app on public ;-)

You have answered your question but this may help.
connect with your wireless network
host the wireless connection using netsh in CMD. an alternative is creating an internal switch sharing your connection with your lan adapter
you can do that with connectify too.
by now, your PC should show you are both connected to a wireless and lan network.
run the emulator from visual studio and you get connected.

Windows OS: Connected dev board not visible in mdt using Git Bash

Doc I followed - https://coral.ai/docs/dev-board/get-started/#install-mdt
Python3 version: 3.9
What I have done
Flashed the board with a microSD card.
I have installed MDT and it is working fine.
Connected the dev board via USB, confirmed a new Network Adapter (Remote NDIS Compatible
Device) shows up in Device Manager
Ran mdt devices
What the docs said should happen
connected dev board should be listed
What actually happened
After waiting for some time nothing gets listed (mdt cannot see the
connected device)
Running mdt wait-for-device stalls in "Waiting for device..."
Running mdt shell gives the error, "Waiting for a device... Unable to find any devices on your local network segment."
This might not be the best way to do this, but this did the trick for me:
First connect your board to your PC.
Go to Control Panel > Network and Internet > Network and Sharing Center
Here you will see an Unidentified network click on it and go to Properties.
In properties, go to Sharing and check Allow other network users to connect through this computer's internet connection.
Now try running mdt shell command.
After you have successfully connected your board, make sure to uncheck the previous option in Network Sharing.
I did the above but it did not fix my problem. Here is what fixed it -
Apparently the dev board is seen as a unidentified network under public networks. My Windows Firewall settings blocked python.exe from writing to or reading to public networks. I did the following -
How to check if Windows Firewall is blocking a program
Press Windows Key + R to open Run.
Type control and press OK to open Control Panel.
Click on System and Security.
Click on Windows Defender Firewall.
From the left pane Allow an app or feature through Windows Defender Firewall.
In the allowed apps window, scroll through all the apps.
Locate the app you want to review and see if the app is checked.
(Here the python.exe was not checked. I changed the setting and voila, mdt devices finds the device and everything works on from here.)
If it is unchecked, the app is blocked on the Firewall.
If your program is blocked, simply check the app and click OK.

How to configure a Linux device to appear in Windows Network Explorer with "View device webpage" option?

I am setting up a Raspberry Pi 2 Model B to serve up and host a local web page at its IP address and I would like the device to appear under the "Other Devices" category of Windows Network Explorer.
I have currently configured Samba on the Raspberry Pi. The device successfully appears in Windows Network Explorer under the "Computer" category. The Raspberry Pi is essentially network-attached storage (NAS) right now.
https://i.imgur.com/95HiKwf.png
The expected behavior is not to configure the Raspberry Pi as a file share or NAS but to be able to open Windows Network Explorer from a PC on the same network, see the device, right-click on it, and be able to click on the "View device webpage" or "Properties" options.
https://i.imgur.com/yainEcE.png
This seems to be common functionality in Network Explorer shared among printers, cameras, and multi-function devices that host local web pages.
Is SMB the right tool to accomplish this task?

Not able to add External Virtual Switch in Hyper-V to connect Android Emulator to Network

I am using Hyper-V to run Visual Studio emulator for android to test Xamarin android app. But emulator is not able to connect to database machine (for making database calls) on same network whereas my computer can access that database.
I have searched a lot on internet but no luck. Even I am not able to add new External Virtual Switch in hyper-v. In my network setting I can see 2 network adapters. One is my physical adapter(Ethernet) to which my computer is connected using LAN cable (Realtek PCIe GBE Family Controller) and second one is vEthernet connected using (Hyper-V Virtual Ethernet Adapter).
Below is the screen shot of hyper-v setting pane of my kit-kat emulator.
It is showing only one switch (window phone emulator switch) not the Realtek Pci Switch. Also I am not able to add a new switch (external switch in hyper-v ) here. Button remains disabled.
Please help me to sort out this. Thanks
I figured out the solution while reading an article for this. For External switch to be added for Hyper-V, we must have Hyper-V Extensible Virtual Switch in our network adapter settings as shown below:
If it is not present then you can add it from install button. It will open a popup window, select Protocol there as shown below.
Once it is added, now you will see External Switch option will be enabled in Hyper-V.

Wi-Fi Direct in Windows 10 (Desktop)

I have recently started to have a deeper look into Wi-Fi Direct under Windows 10 (desktop version) and had a look into the API descriptions
from Microsoft => https://msdn.microsoft.com/en-us/library/windows/desktop/dn457945(v=vs.85).aspx
One of the described methods there (WFDStartOpenSession) states that a previous pairing through the "Windows Pairing experience" (WPS ?) is required.
So i started to play a little bit with the pairing stuff by using a Windows 10 (Build 1607, Desktop) together with an Android-based smartphone (version 6.0.1) and
made the following observations:
When i initiate the connection from my PC to the phone, it "basically" works i.e. the pairing dialog shows up on the phone's display and i can connect to it.
Although it works, it's not really stable in my opinion - on my side it works 1 out of 3 times.
After ~ 30 seconds, Windows disconnects from the phone (in the "Devices and printers" view) while the phone itself stays connected a little longer (then it also disconnects).
When i initiate the connection from my phone to the Windows PC, nothing happens - no message box, no pop-up window :-(
Has anybody else seen this or similiar behavior ?
I tried it with 2 different USB adapters, one with a RTL8723BU chipset from Realtek and the other one with a RT5572 chipset from Mediatek Ralink - both show
exactly the same behavior.
In addition, i noticed that the "Realtek Wireless Lan Utility" to control and configure the USB adapter is not working anymore in Windows 10 (1607) when switching
from client to Access Point mode. I think it's somehow related to ICS, missing hosted network support ... don't know yet.
However, actually you don't need the tool from Realtek as you can for example use the mobile hotspot feature of Windows 10 to share your internet connection with your devices.
But without the Realtek tool i have not found any possibility to switch WiFi channels - does anybody have the same problem ? is there are solution available for that ?
Thanks

Can't start hostednetwork

When I try to run netsh wlan start hostednetwork, I get the following message:
C:\Windows\system32>netsh wlan start hostednetwork
The hosted network couldn't be started.
The group or resource is not in the correct state to perform the requested operation.
I'm running this with admin privileges, so it's not the notorious
C:\Users\Kevin>netsh wlan start hostednetwork
You must run this command from a command prompt with administrator privilege.
How do I get the hosted network "in the correct state"?
This happen after you disable via Control Panel -> network adapters -> right click button on the virtual connection -> disable
To fix that go to Device Manager (Windows-key + x + m on windows 8, Windows-key + x then m on windows 10), then open the network adapters tree , right click button on Microsoft Hosted Network Virtual Adapter and click on enable.
Try now with the command netsh wlan start hostednetwork with admin privileges. It should work.
Note: If you don't see the network adapter with name 'Microsoft Hosted Network Virtual Adapter' try on menu -> view -> show hidden devices in the Device Manager window.
Let alone enabling the network adapter under Device Manager may not help. The following helped me resolved the issue.
I tried Disabling and Enabling the Wifi Adapter (i.e. the actual Wifi device adapter not the virtual adapters) in Control Panel -> Network and Internet -> Network Connections altogether worked for me. The same can be done from the Device Manager too. This surely resets the adapter settings and for the Wifi Adapter and the Virtual Miniport adapters.
However, please make sure that the mode is set to allow as in the below example before you run the start command.
netsh wlan set hostednetwork mode=allow ssid=ssidOfUrChoice key=keyOfUrChoice
and after that run the command netsh wlan start hostednetwork.
Also once the usage is over with the Miniport adapter connection, it is a good practice to stop it using the following command.
netsh wlan stop hostednetwork
Hope it helps.
First off, when I went into cmd and typed "netsh wlan show drivers", I had a NO for hosted network support too. Doesn't matter, you can still do it. Just not in cmd.
I think this problem happens because they changed the way hosted networks work in windows 10. Don't use command line.
Just go on your pc to settings>Network>Mobile Hotspot and you should see all the necessary settings there. Turn it on, set up your network.
If it's still not working, go to Control panel>Network and Internet>Network and Sharing Center>Change Adapter Options> and then click on the properties of the network adapter that you want to share. Go to the sharing tab, and share that internet connection, selecting the name of the adapter you want to use to share it with.
I encountered this problem on my laptop. I found the solution for this problem.
Test this command in the command prompt "netsh wlan show driver".
See Hosted network supported.
If it is no,
Then do this
Go to device manager.
Click on view and press on "show hidden devices".
Go down to the list of devices and expand the node "Network Devices" .
Find an adapter with the name "Microsoft Hosted Network Virtual Adapter" and then right click on it.
Select Enable
This will enable the AdHoc created connection, it should appear in the network connections in Network and Sharing Center, if the AdHoc network connection is not appear then open elevated command prompt and apply this command "netsh wlan stop hostednetwork" without quotations.
After this, the connection should appear.
Then try starting your connection. It should work fine.
First check if your wlan card support hosted network and if no update the card driver. Follow this steps
1) open cmd with administrative rights
2) on the black screen type: netsh wlan show driver | findstr Hosted
3) See Hosted network supported, if No then update drivers
Symptoms
You install an application that uses Microsoft Virtual WiFi technology on a computer that is running Windows 7 or Windows Server 2008 R2. However, the application does not work after the computer restarts. Additionally, you receive an error message that resembles the following:
The hosted network couldn't be started. The group or resource is not in the correct state to perform the requested operation.
Cause
This issue occurs because the Virtual Wi-Fi filter driver does not create the Virtual Wi-Fi Adapter correctly when a PNP resource rebalance occurs during the startup process.
Notes
1.This issue may occur when a Plug and Play (PNP) resource rebalance occurs during the startup process. The PNP resource rebalance is usually triggered by a change to the hardware configuration.
2.If you open Device Manager when this issue occurs, you notice that the Virtual WiFi Adapter is not created.
If you can't restart your hostednetwork after rebooting the OS ,just Try this hotfix .It fixed my problem. Or try to figure it out by yourself according to the Symptoms and Cause mentioned at the start of my answer.
Often, I've found that the solution to this problem can be fixed by disabling and then enabling the Wifi hardware. I've made a script to do this automatically instead of doing it manually by going to the device manager. You can find it here
Some fixes I've used for this problem:
Check if the connection you want to share is shareable.
a. Press Win-key + r and run ncpa.cpl
b. Right click on the connection you want to share and go to properties
c. Go to sharing tab and check if sharing is enabled
Run devmgmt.msc from the run console.
a. Expand the network adapters list
b. Right click -> properties on the adapter of the connection you want to share
c. Go to power management tab and enable allow this computer to turn off this device to save power. Restart your laptop if you've made changes.
Check if airplane mode is disabled. You can enable airplane mode and then turn on the wi-fi, you can never know. Do disable airplane mode if it is on.
Use admin command prompt to run this command.
If none of the above answers worked for you, You can try the following solution which worked for me.
Go to Services manager(services.msc) and enable the below services and try again.
WLAN AutoConfig
Wi-Fi Direct Services Connection Manager Service
Hope this solved your problem.
The hosted network won't start if there are other active wifi adapters.
Disable the others whilst you're starting the hosted network.
Fixed by installing "Wifi Direct Access Point". HostedNetwork is not well supported by some Windows 10 drivers.
