New setup, download software, set up a Pi in my shed with a FA antenna. Instant joy. I claim the unit and the stats start to come in. A day goes by and suddenly no stats and I can no longer connect to the unit. I hook up a monitor and see it states there is no wifi. I check configuration and everything is how I left it. I powered it down, pulled SD card, check txt file and both ethernet and wifi are turned on. Put card back in, plug the unit to a wired ethernet cable and powered up. Connection established and all seems well. I shut it down and take it back out to the shed. Connect antenna and power and the wifi is working again. Another day goes by and now the unit isn’t connected.
I have read about wifi issues. Power save is off so I don’t think it is shutting off the wifi. What can I do to alleviate this issue?
I power cycled and it still showed the same thing. I then connected to an ethernet cable and it started working. I shut it down and then restarted without the cable, no wifi detected.
The network info is the same for both, what should be my next step?
Everyone has a different approach to solve a problem.
My approach is different from most.
When I cannot easily debug, I format microSD card, download and write latest Piaware image (or Raspbian Jessie image), and everything is ok. No headaches, no frustrations, and no waste of time.
I know most will disagree, rather hate this idea.
Well this is MY approach, and everyone is free to chose his approach.
The syslog is the best place to check for problems.
If you run “cat /var/log/syslog | grep wlan0” it should display wlan0 stuff only.
It is also a good idea to check the piaware configuration files has the correct wifi connection settings.
Edit the wireless ssid and password in the piaware-config.txt file if not.
And to see if your wifi can see the access point you want to connect too.
“sudo iwlist wlan0 scan”
The quality score is how many “bars” you are getting to that access point.
If you don’t see your access point in the scan you probably aren’t close enough.
If you have a low quality score you need to get closer or use something with better wifi range.
