Everything is fine in ACER Laptop 1640 (2004)Īnd the same for Puppies 5.8.3 ppm tahr (tahrpup) run by a german Medion P7624, low cost too. I listen to forum for a clever choice when buying an wireless USB, cheap trademark CSL recognized as RTL8192CU by network wizard. So, I'm happy that the dongle works, but concerned about the USB-3 support.Merci messieurs pour vos conseils judicieux. So, is this a problem with the xhci driver? Should the device work in a USB-3 port? That driver is where all those error messages were coming from in my previous post. When I plugged the dongle into a USB-2 port, it connected straight away. Without realising it, I was plugging the dongle into a USB-3 port, as it was the only one available on the front panel of the computer. I discovered that the problem was not with the kernel driver for the RTL8188CUS chip.

I just received kernel 3.1.7 in the latest batch of updates, so I tried again with the built-in driver, but no success. The current version of the driver on the Realtek site claims to work for kernels up to 3.0.2, but I built and installed it, and it doesn't work on kernel 3.1.6. There are lots of forum posts for various distributions indicating that people have had success with the Realtek drivers, but not since kernel 2.6.X. The driver is loaded, the networks are scanned properly, but it won't connect - it just keeps asking for the WEP key, or the WPA key on a WPA network.

The drivers which come with kernel 3.1.X just don't work. Its chipset is RTL8188CUS, which seems to power many of this type of device. I have one of those tiny USB wifi dongles.
