Hello everyone, I’ve been working with 25-30 USB 3G/4G dongles successfully on Debian and Ubuntu, where all connections work without issues. However, on Armbian, I can only establish around 10 PPPoE connections. Here are the details of my setup: OS: Armbian based on Debian 10 (I also tried updating to Debian 11) - IMG: Sunvell rkship and Kernel Version: linux-image-current-sunxi 24.11.1 Packages Used: ppp, eject, and usb-modeswitch (tested with the latest versions) Logs: /var/log/ppp.log doesn’t show any errors. Isos: Armbian 21.05.1 stable, kernel 4.4 (SoC Rockchip rk322x) Armbian 20 - Debian 10 ARM (SoC Alllwinner H3) - Sunvell R69 https://mega.nz/file/4ugAhKjb#NIt6KIv2tsPFzVVGwLcykFSdQp0MgCXgdCzxcj0PUxA https://mega.nz/file/V3QQyBaY#Y332sD2oa36L5BZa0xtANx1O6QrS_903Qj1RHg1vuy8 I’ve read that some kernel parameters may limit handling multiple PPP sessions or high network traffic. For example, I came across the parameter net.core.max_skb_frags, which seems relevant but I haven’t made adjustments yet. Has anyone encountered this issue or know what configurations I can tweak to improve Armbian's capability to handle more PPPoE connections? Any advice on kernel parameters, USB handling, or PPP configurations would be greatly appreciated. Thank you!

I followed the steps outlined in the instructions, and they worked very well for me with (10 ISPs) 4G dongles using PPP connections. TV Box Model tested: MXQ Pro 4K, 5G (H3 Allwinner), ISO: Sunvell 69. I started with Debian 10 and later upgraded to Debian 11. I also use a second USB 3.0 LAN card, as well as the dongles connected through a USB hub with an independent power supply.
