  1. Wifi Adapter shows no RTL818x


    im using a Realtek 8812BU Wireless LAN 802.11ac USB NIC and before i had this issue i was trying to solve a previous issue where the adapter would disconnect itself for no reason, i installed the latest drivers but that didnt work so i uninstalled the device and restarted my laptop, and now the adapter wont work because it has "no RTL818x"

    Wifi adapter disappears - goes 'hidden'


    Running Windows 10 on an Acer laptop. Over the past month, the wifi connection dropped without explanation/warning.

    First time, the adapter was visible in Device Manager (with a yellow triangle next to it). An interent search found the suggestion to uninstall it and restart. That worked.

    Today, the connection dropped again. In Device Manager at first I could not see the wifi adapter listed. I clicked to see hidden devices and found the adapter and the Bluetooth (which I had not noticed was missing).

    I again uninstalled, restarted, and both the wifi and bluetooth have returned.

    Anyone any ideas as to what is happening, why it's happening, and what I need to do, please?

    I have attached a screenshot of the DM windows as it is now, showing the wifi adapter name, etc.

    Thanks very much

    Wifi Adapter

    Here are several methods:

    • Look in the user guide - see if 5 GHz WiFi is mentioned.
    • Find that model on the manufacturer's website - see if the manufacturer advertises 5 GHz capability.
    • Look for independent reviews of your model - the reviewer will certainly mention if the adapter supports 5 GHz

    If none of those provide the answer, I can suggest many more ways to find out.

    Wifi Adapter shows no RTL818x

    Strange RTL818X message

    Hi Mike

    RTL818X refers to your Relatek WiFi device driver.

    Where exactly are you seeing this icon, if possible a screenshot would really help . . .

    Is that some sort of prompt to update your driver and if so, does it mention some kind of Driver updater software>
