I’m not an expert, but network interfaces like wlan0 and eth0 will have their mtu set to 1500, where mtu stands for *looks it up* maximum transmission unit, which has to do with how large the packets can be. For some reason, mobile interfaces like wwan0 should have an mtu of 14xx, the exact number depending on the carrier’s network. Like 142x or 143x, usually, I think. On postmarketOS, using logread, I know says the value somewhere in the log when the mobile connection comes up. So, anyway, if I am using the phone and I say
sudo ifconfig wwan0 mtu (whatever number)
it all works better. And, if using tethering, doing the same on that device for wlan0 in addition.
I’m sorry that I don’t really understand it well enough to give a good explanation. I read it somewhere the other day when I was having trouble.
Also… you may of course be having a completely different problem from mine.
