I have a:

When I connect the Asus laptop to the Samsung Smart TV after 10 minutes it disconnects and it's hard to reconnect.

This is what I've done:

  • Updated to latest driver for graphics card using Asus LiveUpdate
  • Updated to latest driver for WiFi card using Intel Update download
  • Updated to latest firmware for TV using inbuilt software updater

  • Updated to latest BIOS firmware for laptop using Asus LiveUpdate

  • Factory reset Windows 10 Pro

  • Verified that the driver and hardware supports a wireless display using dxdiag

  • Verified that the system supports a wireless display using an alternate method (netsh wlan show drivers command in a command prompt)

  • Tried a LG V30+ Android mobile or Google Nexus 7 tablet device on the Samsung TV. This works fine.

  • Tried connecting the Asus laptop to a different LG webOS UM7600PTA smart 4k TV. This works fine.

I've spent a few hours on Microsoft Directly support; Samsung TV Support and Asus support.

I've asked for support on the web here:

Any suggestions?

The relevant hardware:

  • Intel® Core™ i7-8550U CPU @ 1.80GHz
  • Intel® UHD Graphics 620 with latest drivers 23.20.16.4973 dated 2018/02/28
  • Intel® Dual Band Wireless-AC 8265 with latest drivers 20.70.13.2 dated 2019/09/10
  • Samsung UA55MU6103WXXY 4K Smart TV with latest firmware 1280.5 connected to Wifi Router on 5GHZ band.

Update 2020/01/03

  • Updated Intel® UHD Graphics 620 to latest drivers 20.70.15.1 dated 2019/12/31
  • I forgot to mention. Samsung HQ had me connect both the TV and laptop to my mobile hotspot. They didn't specify the frequency band but it was also 5GHZ.
  • Samsung TV repairmen (Video Factory Electronics) came out but only tested their Android mobile to my Samsung TV which of course works as I"ve already told Samsung HQ. There was not good communication from Samsung HQ and Video Factory.

Still has issue.

I see your specs at Intel
TX/RX Streams  2x2  Bands 2.4 GHz, 5 GHz
(May want to try and only use 2.4GHz).
A lot of places out there don't support 5G yet.

Intel has put out a new driver also Windows 10 Wifi package drivers: 12/31/2019 21.60.2
Hope this helps you out.

Temporary Workaround

  • Connect the laptop to WiFi router via 5GHZ; then connected Miracast; then switched laptop to Wifi router via 2.4GHZ. This works fine for longer then 30 minutes so far.

However this is not a long term fix as 2.4GHZ is slower then 5GHZ. I am still not sure what the root cause issue is.
