just received two Spitz routers for plug’n’play with 4G and OpenWRT.
Tried now setting up the first with a SIM card from German Telekom.
Basic networking comes up but no pongs over the 4G WAN network.
Signal should be fine enough as working with phone at this location.
Did already upgrade Spitz to latest firmware v3.104 with factory reset.
But still not working so we wanted to ask for help on 4G modem setup?
We can also go technical on this but hoped to save on unbringing time.
That’s why we got old MIPS with USB2 and 100Mbit NICs for OpenWRT.
Did OpenWRT and modems in the past but was always a time eater.
So you recommend to stay just on ttyUSB3 for T-Mobile in DE?
What protocol are we using going over USB interface directly? MBIM?
Guess all protocols are bottlenecked with USB2 despite PCI-e card?
Checked on reboot/powerless and the Spitz working fine now
