$ uname -a Linux Adam-Pi 3.18.5+ #744 PREEMPT Fri Jan 30 18:19:07 GMT 2015 armv6l GNU/Linux
I've discovered an interesting problem with my networking setup with my RasPi. I have it connected to three different networks:
- A wireless network with Internet access using a USB dongle and wpa-supplicant
- A wired Ethernet connection to my private network (no Internet access)
- An OpenVPN client daemon connected to a cloud server
The problem happens whenever I connect to a new interface. When I connect my USB dongle, for example, the Raspberry Pi will kick itself off of the wired connection. The same thing happened when I recently configured it with my new VPN - it would disconnect itself from the wireless network. When I looked into it today, I found this on
dmesg after connecting to my VPN:
[13134.532384] wlan0: deauthenticating from xx:xx:xx:xx:xx:xx by local choice (Reason: 3=DEAUTH_LEAVING) [13134.596079] cfg80211: Calling CRDA to update world regulatory domain
It looks as if it was configured to disconnect under a certain condition.
After looking into the first problem I had encountered with ethernet and wlan, it appears as if the Pi completely reboots when the dongle is plugged in. I can't access the reason why (because the Ethernet connection is killed as soon as the WiFi dongle is plugged in). This problem has truly stumped me, I hope someone out there has the experience to solve this.
