I am working with a Raspberry Pi B+ and the TL-WN725N v1* USB Wi-Fi adapter. I got a couple of them cheap, and they're small, so I thought I scored a great deal. I was surprised that Raspbmc had the drivers pre-loaded and just worked with the adapters. However, the other distros that I'm working with seem to have problems with the adapter.
Vanilla Raspbian doesn't seem to work, but it's been a while since I tried and I don't recall the specific error.
With Octopi (11 or 12), the Raspberry Pi will not boot when the Wi-Fi adapter is plugged in. If I plug the adapter in after it's booted, it appears that the Pi doesn't do anything about it. However, I'm not sure if it's supposed to. According to articles I've come across, that's not a good idea because it causes a brown out or power outage. Due to the articles' age, I don't know if that applies to a B+ though. The articles came out before the B+.
With Octopi, I was getting kernel panics and the under voltage rainbow square (if I plugged it in post-boot), but now that I'm using a different cable and a 2 amp power supply, I don't have those (separate) issues.
That leaves me with the following burning questions:
- Does Raspbian now come with the driver for the TL-WN725N or do I have to load a new driver manually? The articles I see are mostly from a year ago.
- From what I can tell, it sounds like the v1 adapter should work automatically with Raspbian. I have 2 different adapters, and they both cause the same behavior.
- Does Octopi add any additional Wi-Fi drivers to the Raspbian base OS?
- Octopi says to edit
octopi-network.txthere, but I don't have a Linux machine. Where might I find that file if I boot into Octopi? (I looked and was not able to find it)
- What are some troubleshooting steps I can take to work this problem?
