my WLAN connection via Edimax dongle gets unstable whenever the camera gets activated by motion software. Response times on the ssh shell are bad and often the WLAN connection totally breaks down.
This happens on two different RPis, two different camera boards and two different power supplies (>1000mA).
When I attach the WLAN dongle remote from RPi and camera board on a (powered) hub, WLAN connection is stable as a rock.
Has someone ever observed this behaviour?
