iOS14 iPhone USB tethering broken for Linux/OpenWRT

A number of forums are reporting that iOS14 iPhone USB tethering is broken for Linux/OpenWRT, though it still works fine for e.g. W10:

https://forum.openwrt.org/t/has-the-ios14-tethering-issue-been-resolved/74949

https://forum.gl-inet.com/t/can-t-tether-w-iphone-gl-ar750s/11286/14

I am personally experiencing this issue. Post my iOS14 upgrade, USB tethering still works fine for me to my W10 laptop, but not via my OpenWRT router (OpenWRT 19.07.04 on GL-iNet B1300). Other forums imply the same broken behaviour on various flavours of Linux :(

Is anyone else inconvenienced by this? And more importantly, does anyone have any ideas how to get a fix/work around?

Thanks.

So guys. It seems that a fix has been found.

https://github.com/libimobiledevice/libimobiledevice/issues/1038

In practice Apple change a piece of protocol and a quick fix (could) exists (https://github.com/jpirko/linux_mlxsw/commit/f33d9e2b48a34e1558b67a473a1fc1d6e793f93c)

Obviously, routers' os vendors have to implement this fix. For example for GL-INET someone has already implemented this one http://download.gl-inet.com/firmware/snapshots/20201126/ for the others (as me) we need to wait for the official patch by our vendor but I hope it's only a matter of time.

Thanks Apple for your support and help your customer during force smart-working due to quarantine and outbreak.

This is the last time I auto-update your FW, and suggest to everyone to switch-off it.

Same problem here.

I can ping the iphone/router address but packets cannot reach internet.

No problem on windows nor setting up a wifi hotspot.

Just for clarification: USB Tethering using your iPhone (iOS14) in combination with a Netgear MR1100 M1 Nighthawk LTE Router is working?

I updated ti ios14.1. No change, still not working.

Is your wifi connection stable? Here it’s dropping after some time. Therefore it’s not a workaround.

Has any 3rd party developers trying to make a new iPhone tethering driver now?

When can we upgrade the ipheth of Linux ?

Oct 22, 2020 8:58 AM in response to Hector Miranda

Hector, are you saying that if i purchase a RT2600ac today, my problems will go away?

Oct 22, 2020 9:04 AM in response to dayzed007

nevermind, I can't even locate one, so that's a non-starter :-(

Oct 22, 2020 9:49 AM in response to dayzed007

@dayzed007 where are you? I just did a quick search and Amazon has it, as well as a number of other retailers like BHPhoto, etc.

Oct 22, 2020 11:07 AM in response to Alan Cook2

Toronto. I came up short on amazon.ca, as well as the other sellers mentioned on the Synology website (most seem to be tech solutions companies, not retailers)

Oct 22, 2020 4:53 PM in response to dayzed007

I'll contact them. I am not sure if it would be helpful, as this was compiled for this specific router.

Did you use the wifi hotspot?

or the ISB Ethernet?
