Last year I had a heck of a time finding a USB WiFi adapter that would work with my Model B based SPRITE robot plugged straight into my Pi.
After testing five different WiFi adapters that I had in my lab, I only found one that would work reliably on SPRITE’s Model B Raspberry Pi without using a powered hub.
With this update, I have now tested eight adapters, three of which will work reliably on a Model B without needing a powered hub!

Fast forward to last week – and the release of the new Raspberry Pi Model B+ … which not only had four USB ports, but a much improved power regulation circuitry.
I wondered… would more of the USB WiFi adapters work on the B+?
YES!!!
This suggested that the Model A, with its single USB port and lower power consumption, may also be able to support more WiFi sticks than the old model B (without an external powered hub)

NOTE: Your mileage may vary, as sometimes manufacturing changes are made to WiFi adapters without changing the model name or number.

There is a (long) thread on the Raspberry Pi forums on how to get the TL-WN725N working with the Raspberry Pi. I was hoping the needed fixes were incorporated in the Rasbian I installed on the B+, however that was not the case. I will try the fixes in the future, and update my test results as appropriate.
I intend to update this article as I get more different WiFi adapters to test.
If you have any questions, you can discuss them in the Raspberry Pi WiFi Adapter Tests forum.
For more details, please see the individual pages for the specific WiFi adapters, which includes the kernel dmesg output when the adapters were plugged in.
