I have made a CVS checkout of the base system source and pkgsrc source fine.Also have watched a 1h 30 m film using minidlna server in VLC over the local network with no failures at all.With bwfm driver that was just impossible. Great work! Regards.
Hello,After a week using the driver I can say that it works well downloading files massively but I noticed I have lost ssh connection two times (both 04:00 to 05:00 in the morning when the system was not doing anything but sending 15s interval pings) (I left a 15 s interval ping script that logged it in a file).Also investigating the logs of my other Zero W with Raspbian I could see that at the precise time the network was lost in the NetBSD ZeroW, the Raspbian ZeroW recorded an association event to the router.
Investigating further I noticed that they could be related to router WIFI channel change. "service network restart" a few times luckly restores connection but not always works. I tried also ifconfig urtwn0 up and down manually with no luck. "service wpa_supplicant" restart does not work either.
I have systematically reproduced the problem forcing a WIFI channel change from the router and network is always lost after that. If you return the router to the original channel it returns working sometimes. (Raspbian ZeroW always negociate ok channel changes)
Leaving the router at a fixed channel could be a "dirty" fix.A channel change seems to be not very frequent, so the rebooting script when network fails could make sense...I do not know.
A bit tired of testing and out of ideas... Regards. Ramiro.
