IPhone Tethering Not Working After iOS 14 Update

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.

I just got off the phone with Apple support. I had to get escalated up and up and up. They said this has happened before with IOS upgrades and they aren't going to do anything about it. It's up to the router manufacturers to upgrade their firmware and that often takes a month or two, according to Apple. So, my choices are to wait and use hotspot in the meantime, or get a Samsung phone (those are apparently not affected) and I need a new phone anyway.

I think, this is Linux kernel or firmware issue. I am using Elementary and MX Linux, which are Debian and Ubuntu distros, and I have the same issue. Tethering via USB not working, hostspot work fine. Yesterday I notice, that MX Linux using network driver for "Iphone 4/5/5s/6". Now I have iphone 7 with IOS14 upgrade. So, we must wait, for linux firmware upgrade.

You need to create a ticket on their support system and ask for the iOS 14 hotpatch:

The most likely reason this doesn't work anymore is that Apple probably had complaints from carriers about abusers of the unlimited plans using tethering to feed routed networks. The carriers (eg Verizon) can control your HotSpot option on your iPhone but Tethering or Bluetooth PAN was not a feature they could control by carrier settings...

Now you apparently cannot get a cabled or PAN Internet connection out of iPhone running IOS 14 or above.

Since I can no longer tether my iphone to my travel router, I tried tethering it to my Dell Laptop. I then turned on

The Windows "mobile hotspot" and got the same result..other laptops can connect but no internet.

I am also led to understand that Samsung adroid phones do not have this problem.

This appears to be an Apple problem. What bothers me somewhat is that Apple has made it almost impossible to roll back to IOS 13..WTF?

i see the same issue using Synology RT 2600ac, tested the phone before updating it worked perfect, after update i see a connection of the router to the phone (got an ip from the phone, and showing mobile network signal strength) but the router itself says limited Internet connection. All testet at the same place wher i have LTE mobile connection.

Having same issue with GL-iNet router running OpenWRT. I use this to work from our holiday home in the Highlands and have been doing this for several years. Local LAN connectivity is fine, as is DNS but no internet connectivity via USB tethering. Having to use my backup Samsung A6 instead. Been an iPhone user since the 3 but unless this is sorted this will have to be my last 🙁 Lost almost an entire day figuring out it was the phone that was my issue!

I spoke with Apple support about 2 weeks ago and they said they aren't going to fix it.

I then contacted GL-Inet and they sent me this reply:

"I believe this will be fixed in the future but I am not sure when, it

may take several months or longer. For urgent use I suggest changing

to another phone."

I have contacted Tech Support.

I use Ubuntu 20.04 LTS and also have used 18.04 LTS tethering to the pre-14.2 OS with no issue.

Checking on my system, it clearly is NOT getting a route for the path... I see an IP address assignment, Netmask, and Broadcast address, but no gateway address.

My windows desktop appears to be working w/o issue, using my iPhone X w/ 14.2.

I wonder if these guys test their setups...if they did, they would've easily found this issue.

STILL waiting for an update from these guys...should charge them my $175/hr fee for troubleshooting this crap.

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

Tethering via WiFi works but not on usb cable any more... on iOS 13 worked fine, Windows and Ubuntu detects the usb ethernet adapter but no internet...

I spoke to Apple support..they said they aren't going to do anything. You can wait for a firmware fix or get a Samsung phone

Could be a security problem with router, patch needs to came from router vendor.
