IPhone Tethering Not Working After iOS 14 Update

You should check out this about troubleshooting: github libimobiledevice libimobiledevice issues 1038

Packet analysis shows how Win10 systems are sending packet types that were not necessary for IOS 13 USB tethering, and the services that support those are at least in part now obfuscated. The appearance is that the new IOS 14 tethering is engineered to behave in the way we see and to be difficult to establish without a full tethering specification at the packet level from Apple.

Was that information readily available to the devs for various Linux distros and firmware? I don't know the answer, other than that it appears at the moment that just one Linux-based networking device has a patch to allow tethering with an iOS 14 device.

Finding the issue is not difficult. Fixing the issue appears to have a higher degree of difficulty. I've done a small amount of packet inspection myself, and while I got results, I found it neither easy nor fun. If you have skills to lend to the effort in the page the search terms I gave leads to, I am sure they would appreciate the assist. I'd appreciate having a wider range of Linux devices able to use iOS 14 tethering.

Thank you for the feedback...Who was the Linux vendor and where is their patch...I can grab a sample of the exchange to look for the same pattern.

I’ll look at the GitHub article.

Clearly iOS changed their behavior.

I have the Same problem, updates have not helped, now I get ads for new iPhone. Now I use a Samsung phone to tether. Sounds like a plot to sell more phones and cell companies to sell more hotspots. Control communication in time of crisis, you control people.

I went ahead and ordered a Synology RT2600ac from Amazon Warehouse for $130. I got it up and running and confirmed that tethering works with iOS 13 but not iOS 14. I contacted their support and asked them for the hotpatch, applied it this morning, and now tethering works in iOS 14. My thoughts are if Synology can do that, other vendors, and the wrt community in general, should be able to also.

The problem has been fixed for my router.

I use GL.iNET AR750 and the small yellow 300M mini and both now work.

You have to install the last beta firmware update from the manufacturer site.

Their routers are quite cheap and this solution can be useful for who, like me, need this feature for work.

The GL.iNet routers are a good option right now because of this iOS 14 situation. You can pick up the GL-AR150 model for about $25. Tether your phone to that, then take an ethernet cable from the LAN port and plug it into the WAN port of your main router to give internet to your whole network. Just make sure your IP addresses are set up right. The 150 comes preset at 192.168.8.1, so if your main router is set at 192.168.1.1 you're all set.

After updating to iOS 14 on iPhone tethering not working, no internet connectivity. Wifi works

I can confirm that this is affecting me also. I upgraded to iOS 14 on the day it was released and have not been able to tether via USB to my Netgear router running dd-wrt since that time.

I am also having this issues. I hope this gets visibility it was nice to have a backup WAN for the kids remote school zoom meetings.

Has anyone found a solution? Trying not to reset iphone to see if it works.

Same here..I tether to a GL-Net GL-MT300N travel router. GL-Net has acknowleged the problem and says they're working on a fix

but don't have one yet..

Has anyone tried updating to the iOS 14.2 beta to see if it has been fixed?

No, but I've that read in other forums that it doesn't help

I’m currently using the latest 14.2 beta on my 11 pro max, and USB tethering with my dd-wrt router is still not working.

I can confirm that Synology has already figured it out and they have a minor unofficial patch available for the RT2600ac that fixes the problem with iPhone USB tethering with iOS 14.
