In January I was working out of a co-working space with a Pi 2 on a 48-hour hackathon project. There were no RJ45 (LAN) connections available, only WiFi. To top it off, I had forgotten my keyboard at home. Until I managed to borrow a keyboard I was stuck. I couldn’t configure my WiFi dongle to to get SSH access. Once I had WiFi and SSH, I could proceed and everything worked fine.
With the Raspberry Pi 3 out, and the eventual Model A coming with wireless but no RJ45, I thought it would be a good time to toss around ideas for setting up WiFi on a Pi. Starting with the more obvious options:
- The keyboard/screen approach even if it’s going to be headless later. The official 7" screen is an option to transport a smaller screen. I haven’t yet picked a portable (tenkeyless) keyboard specifically for the Pi.
- Plugging in an RJ45 cable to SSH in. Bonjour networking works by default on Raspian so raspberrypi.local is available rather than trying to find out the IP. Then configure WiFi.
- There are serial cables, but I’m leery of installing kernel drivers on my Mac to support them. Maybe they would work from a Linux VM?
- Maybe a program could run on a Display-o-Tron 3000 to pick WiFi, but entering a password would be a pain without a keyboard. And there is the matter of running that program, and including it on the microSD card or image in the first place.
What would you do?
