Cannot connect to wireless display (roku)

[tlaurance]

I cannot connect my my hp-15ay103dx (intel i5) to a wireless display which is connected to a  roku 3 with wireless display turned on. We have two other laptops in our household with similar specs that are able to connect to this display, but on this laptop (the hp-15ay103dx), the display will not appear in Windows 10 as a selection or option to connect. 

My husband's laptop (a Dell) and mine (this HP) are both brand new with similar specs. Also, our daughter has a laptop (a Dell) that is about a year old that can also connect to the same device wirelessly -- so we are more than familiar with how to connect to it. My computer (HP) was purhased about 2 weeks ago and all Windows updates have been done (even a huge 4 gig one in the past few days).

I will try to connect to this device using windows button +P.  The sidebar will appear with options. I will click on a selection (Extend, for example), then click 'Click to wireless display' text below. The system will search, but not find a wireless display to project to. I have tried to click 'Search' and enter the name of the wireless display, but I will get the message, "Looks like we cannot find your device. Make sure it is turned on." The device is definitely turned on and available because my husband can connect to it using his brand new Dell using the same procedure and sitting right next to me. Also note that the device is listed in my network under 'Other Device -- but for some reason my system will not recognize it as a display.

I have looked at my husbands specs to see what might be different. We both have the same Intel i5 7th gen processor. We both have the same Intel HD 620 graphics card. The only difference is my display adapter driver is older than his (mine is Nov 11 2016, his is December 2016). The display adapter driver installed on my laptop for Intel HD Graphics 620 is version 21.20.16.4550 (11/11/2016).

When I search for an updated driver through HP, the latest driver listed is an older version than the one that I have installed (Nov 4, 2016 - .4526). Should I roll back the driver? If I do, will windows update it automatically?

Also, I do find even more recent drivers on the Intel site, but when I try to install, I receive the message it isn't compatible with the manufacturer's configuration and the update will not install.

We bought both laptops with specific specs with the intension of using miracast (widi). We are pretty disppointed that this one doesn't work. At this point, I'm not sure whether the problem is the display adapter or not, and if it is, will the older OR newer display adapter driver fix the problem? 

Can anyone help me find a workaround solution so this laptop will cast to our wireless display?

Hi:

Looking at the specs for your model, it is not capable of wireless projecting to a display, or other device such as a Roku.

The Realtek RTL8188EE-VJ 802.11b/g/n 1x1 Wi-Fi adapter your notebook comes with, is not capable of wireless display transmission.

Thank you for your reply. I'm surprised we missed this -- perhaps we assumed this technology was only needed within the video adapter and/or processor.

Can the wi-fi adapter on this model be removed and switched out for a different wi-fi adapter that supports wireless display? We are looking for specific brand/model suggestions to replace the current adapter without using a dongle or external USB connection.

You're very welcome.

A PC with Intel hardware such as yours, needs to satisfy 3 requirements to screen mirror...

Compatible Intel processor, compatible Intel graphics, and a compatible wireless network adapter.

You have two of the 3 requirements.

Unfortunately, I don't know what model wireless cards are supported in your model, because there is no service manual linked to the support page.

The other issue would be that your notebook must have two antennas to connect the upgraded wireless card with.

So, unless your notebook has two antennas in there, a better wlan card wouldn't work.

It will also be very difficult to access the part of the notebook where the wireless card is located (see chapter 6).

The service manual for the ay000-to ay099 model series, chapter 3 gives the list of supported wlan cards for that model series.

The following cards from that manual would support miracast/screen mirroring/wireless display...

Intel Dual Band Wireless-AC 3165 802.11 ac 1x1 WiFi + BT 4.2 Combo

The Intel 3168 card isn't listed on the above page, but the product brief indicates it does support wireless display.
