Hi @fencer ! I was giving some thought to your (puzzling, indeed!) question. I am afraid I don’t have a definitive answer, but here are some things you may want to look into:
- First, take a look at this thread from 2020. Seems to be a similar issue, so some of the troubleshooting ideas may help you. (Sadly, in this case the user ended up giving up on the BBGW
) - Did you check the kernel logs (with
dmesg)? Perhaps some peripheral on the BBGW is hibernating after some time? - This is a long shot, but in the recent times we have seen various users having networking issues with cellular connections because the carrier changed some configuration without notice. Notably, some were reducing the MTU, so the device would fail to send packages because it was still using the old, larger MTU. (Doesn’t seem to be the case here, but maybe this can give you some idea.)
I hope this helps – and please let us know if you find any other clue!
