I use a K5160 dongle that works fine with a 2015 laptop that has had Windows 7 and 10 on it.
Yet when I tried it on a new laptop with Windows 11 I couldn't even get past the Windows registration process as the laptop would recognise the device, connect, then promptly disconnect seconds later.
I have also tried K5161h but get the same result. Vodafone say it is compatible with W11 but I am not convinced. Does anyone know for certain and if it is compatible, what do I need to do to get it to work?
