Wireless – Can I Hook up my iPonic to WiFi?
If the customer can get a line of sight between the office and greenhouse, there might be a wireless solution that works at the range. (If a line of sight (no trees, buildings in the way) can be reached.)
If a range is not available, you must obtain internet at the greenhouse.
There are Ethernet to WiFi adapters that you can buy from Amazon. Please follow the manufacturer's instructions.
