iPhone (iOS 15.6) Tethering problem

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?

Version: 3.215 beta1
