Hi,

Recently i've been having a problem where my laptop wont be able to use the internet through my phones hotspot. My phone itself can still connect to the internet, and even pair and connect to the laptop, but no internet connection on the laptop itself. i believe the problem started after the windows 11 major update.

i have an iphone 12 and im with Vodafone. i've checked my data plan and i have over 200gb still left.

i have already tried :

checking the drivers for updates

renaming the hotspot & changing the password

connecting via Bluetooth

forgetting the hotspot and reconnecting

any help would be greatly appreciated as i use my laptop with hotspot often.

Thanks

Update (reply to original thread reply) - i tried resetting my iphone network settings, this worked but only for about 30 mins before dropping out again.

my Random Hardware MAC Address is already disabled and maximise compatibility is on

id be happy to share the results of ipconfig/all just after confirmation that im not publicly sharing anything that could compromise my security

thanks
