iPhone (iOS 15.6) Tethering problem

Technical Support for Routers
1

Hello,

I have a problem with tethering working on my iphone (iOS 15.6). My GL-XE300 Puli (Version: 3.212) is get the IP correctly and the internet works like about 3-4 minutes after which it stops working. In the logs I noticed :

user.notice firewall: Reloading firewall due to ifup of tethering (eth2)
kern.err kernel: [ 5312.773582] ipheth 1-1.3:4.2: ipheth_rcvbulk_callback: urb status: -79

According to Google results, this is a known bug for years (since 2020) that should be patched by now.

Is the GL version of openwrt still prone to this bug? How to solve this problem?

Best Regards

This fix has been integrated into our firmware. In fact, it was our engineer who submitted this issue at Openwrt.

iOS disconnects no-traffic hotspots when hibernating, did you turn off the screen of your iOS device?

Yes I turn off screen on my device, but for 100% I have traffic because I have connected 6 devices (each device is connected to other VPN [mix protocols WireGuard/Openvpn TCP/UDP]) so each device can send very big packets in 1 connection.

I have other router based on DD-WRT ( v3.0-r49418 std )and here everything works correctly on the same cable, also with off screen etc. from 20 hours I don’t have any crash.

On GL-INET I have crash randomly from 20 seconds to 4 min. (but when I use wifi repeater from iphone everything works, I have only problem with cable tethering)

We will try to check if we can reproduce this problem.
Maybe you can try to use tethering with 3.215 beta?

Hello,

I have a very similar issue like the topic starter. Once this issue shows up, my iPhone 14 Pro max, iOS 16.5, which I use for tethering, stops transmitting traffic to the router:
ipheth_rcvbulk_callback: urb status: -75

@yuxin.zou has there been any progress on that proposed fix?

Best,
Maurice

Having the same issue since upgrading to 16.5

@maurice @Timp
Is your device model Puli? Can you try it with the 4.x firmware?
We tested tethering to iOS 16.5. It worked fine with firmware 4.3.2.

Hello,

I have been experiencing the same issue with my GL-AXT1800 (firmware v4.5.16) + iOS 17.4.1. This has been happening since forever unfortunately.

This is the error:

ipheth 1-1:4.2: ipheth_rcvbulk_callback: urb status: -75

The only solution is to disconnect+connect the iPhone again, but the connection only lasts about 1 minute or 2. It’s extremely frustrating and I had to use an external mobile modem only because I find no way to use my iPhone!

Is there any solution?

Thanks

Please try to reset your iOS network settings:

If you’re using iOS or iPadOS 15 or later, tap Settings > General > Transfer or Reset [Device] > Reset > Reset Network Settings.

If you’re using iOS or iPadOS 14 or earlier, tap Settings > General > Reset > Reset Network Settings.

This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you’ve used before.

Thanks. I tried already, but it didn’t work. Also, the tethering/hotspot works fine with any other device.

I read other discussions and I believe it’s a kernel issue that was fixed, but it’s a OpenWrt kernel version that is not supported by the AXT1800 but only from the newer MT3000?

I can’t find the discussion anymore but it was a bug fixed in a newer OpenWrt kernel version that the AXT1800 does not support.

We tested the same here with 4.5.16 with iOS17.4.1 and it can connect without issue.
