internet tethering

Hello and welcome to Apple Support Communities, Jooce69!

I understand you're not able to maintain a connection between your iPhone 8 and your iMac. I'd be happy to provide information to help you address this.

Make sure you have the latest updates installed both for your device and your carrier:

Update your iPhone, iPad, or iPod touch

Update your carrier settings on your iPhone or iPad

If the issue continues try changing your iPhone name in Settings > General > About > Name.

Test to see if the issue continues. If it does, attempt to Reset Network Settings.

If the issue continues, reach out to Apple Support for further assistance.

Have a great day!

Here is some info regarding using your phone's hotspot:

Hi Jooce69

What iMac do you have and what operating system is installed?

If you are using macOS Catalina ...... are you on Version 10.15 or the updated version 10.15.1 ?

The updated Catalina fixed MANY problems! 😉

Thanks for clarifying, Jooce69. Nothing wrong with El Capitan - I have that on my old iMac! 😉

I'm a keen narrowboater and use my iPhone as a hotspot whenever I'm on board. I find that it's fairly reliable - unlike the 3G or 4G 'phone signal which is unavailable in many places. 🙄
