I set up a few rpis in our production hall to scan barcode. Unfortunately wifi isn’t very stable. When a raspberry loses the wlan connection it doesn’t reconnect automatically.
We also have a few android smartphone which do the job pretty well. Seems they are able to reconnect automatically.
Any idea how to handle this?
Tryed to set a static ip and ‘wlan0’ in /etc/network/interfaces to ifup over a cron job like mentioned here. Couldn’t get the wlan connection work via ifup.
iface wlan0 inet static
