Bump to the 8192cu-dkms v4.0.2_9000-9, with the new rtl8xxxu kernel 4.4 upstream driver blacklisted.

light0 commented on 2016-02-17 18:51

Problems, problems, lots of problems. So how are we going to get this fixed?

NoMore201 commented on 2016-02-17 15:34

I confirm issues with kernel 4.4.1, unusable with university wireless network, frequent disconnections with home wifi. Downgraded to 4.3.3 and working fine.

BasioMeusPuga commented on 2016-02-15 08:23

While this is still better than the kernel driver, I'm afraid that with the update to 4.4.1, my RTL8192CU reports incorrect bit rates, has had its link quality drop to less than half, and is now prone to the occasional disconnect/reconnect thing.

The official Realtek driver (that this package uses) was updated back in 2013. So I guess this is about the kernel now.

runnytu commented on 2016-02-08 20:48

With kernel 4.4.1-2-ARCH works properly for me, no problems.

light0 commented on 2016-02-08 18:37

I can confirm observation by mrueg that this package is not properly working with kernel 4.4.1-2. This package is much needed because the kernel driver does not work well with certain TP-LINK devices (e.g. Realtek Semiconductor Corp. RTL8192CU 802.11n WLAN Adapter), causing frequent disconnects.

Mr.Elendig commented on 2016-02-08 17:41

Use the rtl8xxxu driver in the kernel instead unless you have really good reasons not to.

mrueg commented on 2016-02-07 21:31

I updated to kernel 4.4 (specifically linux-4.4.1-2) today and the module stopped working.
It works after downgrading to 4.3.3-2.

I also tried to uninstall it, reboot, then reinstall it as sourc7 suggested, which didn't help. What should I do to get more information on what went wrong?

I'm running kernel 4.3.3-2 on an arch installation from the 1-1-2016 install iso. I installed this package due to frequent disconnects with the kernel drivers, and now I get three errors to either stdout or stderr (the same one thrice at once) either once I plug in the device or on the login terminal at boot if the device is connected. The errors go away when I uninstall the package and reappear when I reinstall the package. Also, unlike the kernel drivers, Network Manager no longer connects at boot nor will it work manually, not even sensing the SSID at all except like 1 out of 10 times when I re-plug in the dongle or boot, the errors dont appear and it works fine (noticeable improvements in connection speed when that happens though :-D). I have a TP-LINK TL-WN822N rev.3. Here is what happens when I boot. The errors also appear if I plug in the device post-login:

[Terminal Text]
Arch Linux 4.3.3-2-ARCH (tty1)

any ideas?
