Hi, hope this is the right forum for this

i bought this https://www.amazon.co.uk/dp/B098SPYRPZ/?coliid=I1F5ZN28LMVRV9&colid=2GU54UVWAJOAS&psc=1&ref_=list_c_wl_lv_ov_lig_dp_it

It says there's no driver to install. i plugged in but it's not showing a network to connect to.

In device manager its showing in "Other Devices" with a black exclamation mark within a yellow triangle. i've tried updating drivers for this and on "Network Adapters" but all up to date.

Is there something i'm missing or is this not compatible with my laptop. i'm on Win8.1 which it says it supports.

Thanks for any help

Oh darn scam sited. I'll find a better link.

Try this one

https://driverpack.io/en/hwids/USB%5CVID_0BDA%26PID_C820%26MI_02?os=windows-8.1-x64

Extract files then manually update the driver via device manager.

Download it direct from Realtek. Create a System Restore Point first.

https://www.realtek.com/en/component/zoo/category/rtl8811cu-software

On the page cryptodan linked to you need to download the zip file then extract the files. You then need to use Device Manager to update the driver. This is probably the best way as the driver is small compared to the Realtek link I posted.

https://dl.driverpack.io/driverpacks/repack/WLAN-WiFi/Realtek/81x64/U_1030.29.0629.2018/Realtek-81x64-U_1030.29.0629.2018-drp.zip

Unzip the file to a folder on your desktop. Right click the device in Device Manager and select Update Driver. Select Browse Computer for Driver Software then browse to the folder on your desktop. Check the box next to include subfolders.
