More exploration: I tried swapping out a separate AT&T SIM from a cradlepoint unit to see what would happen. Even after 10 minutes or so I'm seeing in the logs...
 Just as a comparison, testing through a [Cradlepoint router](https://amzn.to/3zyWWkO) in the same location with AT&T (though it has a nicer antenna configuration): ``` pi@lte:~ $ speedtest-cli Retrieving speedtest.net configuration......
Tested the Quectel with the SixFab SIM upstairs too: ``` pi@lte:~ $ speedtest-cli Retrieving speedtest.net configuration... Testing from Amazon.com (3.239.194.21)... Retrieving speedtest.net server list... Selecting best server based on ping......
I swapped in my own iPhone AT&T SIM (though on a limited data plan), and it seems to have connected immediately, no fuss. With a different antenna, I'm getting signal...
@danmanners - My guess is the USB D+/- lanes on slot two are also wired into the BMC's USB hub, therefore I'd hit the same issue on that slot :/
The Turing Pi 2's slot is now working, thanks to the removal of this tiny resistor: https://twitter.com/geerlingguy/status/1481027568052711425 I also just received another CM4 board with a mini PCIe slot and...
So new question / problem: - I have `eth0` and `usb0` both providing Internet access on different subnets/networks. - I would like to have things like `speedtest-cli` route only through...
Ah... trying out `ifmetric` as suggested in [this answer](https://superuser.com/a/1260798): ``` pi@turing-node-1:~ $ sudo apt install ifmetric pi@turing-node-1:~ $ sudo ifmetric eth0 220 pi@turing-node-1:~ $ route -n Kernel IP routing table...
So, looks like I may need to do my own route table modifications... ``` pi@turing-node-1:~ $ ip route list default via 10.0.100.1 dev eth0 proto dhcp src 10.0.100.250 metric 202...
