Get Miracast working on Surface Pro original with TH2 10586

 

I wrote about how Microsoft broke Miracast for Surface Pro original users when Windows 8.1 was released http://digitalmediaphile.com/index.php/2013/10/26/how-to-make-miracast-work-on-surface-pro/ and surprise, surprise, they’ve done it again with TH2 Build 10586. The supplied driver for the Marvell Wireless is not Miracast enabled. I don’t know why, as the chip is the same as the Surface Pro 2.

Here’s an unsupported way to get Miracast to work on your SP original with 10586.

Go to http://www.microsoft.com/en-us/download/details.aspx?id=49042 and download Surface Pro 2\SurfacePro2_Win10_150818_0.zip. Open the archive and copy the WiFi folder from SurfacePro2_Win10_150818_0.zip\SurfacePro2_Win10_150818_0\Drivers\Network\WiFi to your desktop or other place where you can easily find it. Then follow these instructions:

  1. Type Device Manager in the Cortana/Search box and open it.
  2. Find Network adapters, expand it, right-click on Marvell AVASTAR Wireless-AC Network Controller, and then select Update Driver Software.
  3. Select Browse my computer for driver software.
  4. Select Let me pick from a list of device drivers on my computer.
  5. Click Have Disk.
  6. Click Browse.
  7. Navigate to the Wifi folder (it has the INF file for the wifi driver), then click Open.

Go to the Action center, select Connect and your Miracast device should be discovered. Connect and enjoy!

Update Your Microsoft Wireless Display Adapter Firmware

 

Microsoft has released a firmware update for the Microsoft Wireless Display Adapter which may help some users experiencing connection problems (black screens, disconnects, etc. The “gotcha” is that in order to update the firmware, you have to have access to a TV/Monitor where you can make a successful Miracast connection and run the Windows Store App http://apps.microsoft.com/windows/en-us/app/microsoft-wireless-display/92ecc09f-9f01-4f9d-9e04-dd412d758b1a that lets you update the firmware. Once you have connected successfully to a Miracast session, here are the steps to update the MWDA:

 

1. You need to create a password in order to access settings and update firmware, minimum six characters. Create this password and confirm it.

mwda1

 

2. Update message will appear (close the app and sign back in if needed). Select Download.

mwda 2

 

3. Tap/click the blue update button

mwda 3

 

4. Tap/click the Start button

mwda 4

 

5. You can view the progress bar (and also you can view on the connected TV; the update is very fast and you might miss it if you blink!

mwda 5

 

6. You will see a success message (hopefully).

7. Close the app and verify you can connect to the TV that you used to perform the update.

8. Connect the MWDA to the TV you previously experienced problems and see if your issue is resolved.

Trouble Shooting Miracast

Updated April 24, 2015

In general to mirror your display using Miracast, both the source and the display receiver should be Miracast certified. You can check devices at https://www.wi-fi.org/product-finder-results?capabilities=2&items=300 and also download a spreadsheet with all Miracast certifications. The first step in solving Miracast connectivity issues is verifying your devices are certified.

If your devices are certified, but Charms, Devices, Project does not offer “add a wireless display”, check for software that might disable Miracast functionality by hooking into the network stack.

Software or Policies that may prevent Miracast from Working:

 

1. VPN software (note that Netgear ReadyCloud software also adds a hidden VPN device and may be installed by the Genie installer).

Some third party VPN solutions identify WiFi Direct (the underlying technology for Miracast) as a “Split Tunnel” and deem it a risk to security so they disable the functionality.

Windows 8.1 has built in support for some third party VPN solutions, but not all. Currently supported are Checkpoint VPN, F5 VPN, Juniper Networks Junos Pulse, Microsoft, and SonicWALL Mobile Connect. You will need to uninstall third party VPN clients (and restart) and then configure. If your VPN solution is not supported, you will probably need to completely uninstall it and reboot to use Miracast successfully.

To setup a native VPN connection:
First, access Windows 8.1 native VPN connections: from the Start screen type VPN and search

vpn network

and then select Manage virtual private networks (VPN). You can then select one of the supported VPN solutions and complete the setup.

 

vpns supported

2. Some group policy settings or firewall settings if you are on a domain. This thread on TechNet may help you resolve this issue: https://social.technet.microsoft.com/Forums/en-US/8a1060b2-2e79-49b4-bcca-76c15a639513/miracast-broke-after-connecting-to-domain?forum=w8itprogeneral

3. Third party anti virus and/or firewalls – recommend completely uninstalling these, restarting, and then checking to see if you can add a wireless display. If you are using a third party firewall like ESET Endpoint, you may be able to create a firewall rule (see http://blogs.msmvps.com/wnewquay/2015/04/24/surface-pro-3-wireless-display-adaptermiracast/ for information on ESET Endpoint).

4. Third party virtualization software like VirtualBox – either uninstall VirtualBox or uncheck the VirtualBox item in Wi-Fi Properties and reboot.

5. Netgear Genie installs a virtual adapter called NETGEAR Firewall Driver similar to the above VirtualBox Drive. Either uninstall the Netgear Genie software or uncheck the item in the properties box and reboot.

 

Stuttering

 

Bluestacks is known to cause audio and video stuttering on the Surface Pro 3. Uninstalling Bluestacks resolves the issue.

 

Microsoft branded Wireless Display Adapter fails to connect, everything else looks good.

 

If your Microsoft Wireless Display Adapter doesn’t negotiate a connection with your computer or tablet, the following may help. This process may work for other branded Miracast dongles as well.

1. Go to Control Panel and open Device Manager and expand devices

2. Uninstall the Microsoft Miracast Display Adapter

3. Unplug  the wireless display adapter from the power source and the monitor and then re-connect Microsoft Wireless Display Adapter to monitor and power it up with USB power source or USB AC adapter from another device.

4. Reset the MWDA

•Press and hold the Reset button for 10 seconds.
•When the button is released, you will see the LED light blink on the adapter and a message on the TV that indicates it is resetting. Wait until it indicates “Ready to connect”.

5. Restart your computer. Rediscover the MWDA – Slide in from the right side and selected Devices from Charms. Select project and then Add a Wireless Display. Connect to the Microsoft Wireless Display Adapter.

Having trouble getting MS support to give you a link to a HOTFIX work around

 

Here’s a trick if you are desperately trying to get your hands on a hotfix from Microsoft that requires you to contact support and are getting a run around. Do this at your own risk. Make sure you need the fix and have created a restore point if things go wrong. I won’t support you and Microsoft won’t support you.

 

You need to know the KB number of the hotfix you need. Find a hotfix (OK, I’ll do it for you) for a different item where the download is available without going through contacting support again. Like http://support.microsoft.com/en-us/kb/2955769

find one

Click the Hotfix Download Available button.

 

After selecting that link, an URL will appear in the address bar like https://support.microsoft.com/en-us/hotfix/kbhotfix?kbnum=2955769&kbln=en-us

Copy the URL in the address bar and paste into Notepad.

Replace the KB 2955769 number with the one you are having difficulty getting. So that you have a link like https://support.microsoft.com/en-us/hotfix/kbhotfix?kbnum=XXXXXXXX&kbln=en-us where XXXXXXXX is the KB number you are having trouble getting.

Now you can get your hotfix.

Again, I won’t support you and Microsoft won’t support you, but maybe you can fix your problem without multiple calls to support and incompetent poorly trained support agents.

How Miracast Communicates Over Wifi Networks

 

Miracast adapters like the Microsoft Wireless Display Adapter and the Netgear PTV3000, etc. negotiate a connection with the source device. To do this, they broadcast a message that basically announces that they are available for a connection. To do this, the adapter will use one of the three non-overlapping 2.4GHz 802.11 channels (1, 6 and 11) which in essence are the lowest common denominator and would be the most broadly available and used channels. (For this reason, if you are on a device that allows 5GHz only connections and suppresses 2.4 GHz, you cannot connect). Therefore, 2.4GHz is a requirement to negotiate a connection using Miracast.

1. If 2.4GHz is the only frequency supported by your router, then issues might occur due to saturated channels from nearby routers in your environment. You might try changing the channel on your router to see if conditions improve. To see all the Wireless channels nearby, open a cmd prompt and type:

netsh wlan show networks mode=BSSID [press Enter]

2. If you are connected to your router using a 5GHz channel, the Miracast frequency can be negotiated to use 5GHz (but remember, the negotiation initiates over 2.4 GHz).

3. If you are not connected to a WiFi network, the Miracast connection will always be negotiated on 2.4 GHz

A Miracast session creates a virtual, second network on a direct, peer to peer basis between your host computer/device and the target Miracast display/Miracast enabled TV/Miracast adapter. You can see this in the Network and Sharing Center in Windows 8.1 after a connection is successfully made:
