I don't know if you are joking or not.
rtl8192cu driver is very stable and works like a charm: tested personally with Vu+ dongles and some D-Link who uses that chipset.
If you refer to Ralink chipset, you have posted in the wrong thread.
In any cases before release the driver into a BH image I test carefully them with all devices I have in my home and I've A LOT of wireless dongles and not only one or twos and I buy some new dongles for testing purposes only.
If your friend want to register here, we can start talk about code ...
I want to remember that BH images uses open sources wireless drivers and they are tested with some dongles, as reported above, and with some Access Points and Wireless routers/modems and in any cases the properly working of devices is confirmed by the fact the new Ralink driver was included some versions ago in the production image.
If a driver has a bug, we can TRY to fix it but WITHOUT a case test able to reproduce the error, it's IMPOSSIBLE for me (or other Team mebers who works on code) to determine the real cause of the problem.
I hope this post can be very clear for everyone who think that BH software is bad: DRIVER can be bad. Image has strongest structure built during YEARS.
