I got the Edimax dongle setup, and its working as expected, but its unstablie/looses connection efter some time. I added a ping request in cron every min, to keep it awake. also disabled power management. as described in http://docs.brewpi.com/installing-your-pi/rpi-setup.html#setting-up-wifi
Im not a linux guy, so I dont know where and how to look for a log file, to see what happend, anyone got any ideas?
A few spots you can look for logs:
- Most all logs will exist in /var/log/ (the two to pay attention to are messages and syslog, in this case I think messages might be more useful)
- Find the wifiChecker script in the utils dir and see where it is writing the stdout and stderr files and dig through those.
WiFi on the RPi has always been a bit of a PITA, but the dongle you have is pretty solid and should work well.
I hope this helps a bit.
I have found the same with an Edimax dongle and a DrayTEK wireless access point and did the same with a regular ping to keep it alive.
It seemed to get worse over time so I bit the bullet and ran an ethernet cable cable to it and the connection is now rock solid.
Sorry this probably doesn’t help but your not alone.
