[Bug 1525254] Re: The r8188eu driver shipped with wily is broken, new working driver exists
** Tags added: latest-bios-2.10

Status: Confirmed => Incomplete

The r8188eu driver shipped with wily is broken, new working driver
Status in linux package in Ubuntu:
After update to wily, I have continuous disconnections with a tplink
725N wifi usb dongle that uses the r8188eu driver to the point that
the dongle is completely useless.
In vivid, the driver driver shipped with the kernel was problematic
but working a bit better (some disconnections, and incorrect link
quality reporting, but OK for the rest) so we definitely have a
Furthermore, on the tplink driver the *source* or a driver that works
fine is available:
Porting to a format consistent with the pristine kernel has been done,
The thing still does not compile cleanly against the 4.2 kernel
shipped in wily, because the interface of cfg80211_disconnected has
changed, but the fix is trivial
diff -r rtl8188eu-linux-driver/os_dep/linux/ioctl_cfg80211.c rtl8188eu-linux-driver2/os_dep/linux/ioctl_cfg80211.c
< cfg80211_disconnected(padapter->pnetdev, 0, NULL, 0, GFP_ATOMIC);
> cfg80211_disconnected(padapter->pnetdev, 0, NULL, 0, false, GFP_ATOMIC);
Furthermore there is a re-definition that needs removing
diff -r rtl8188eu-linux-driver/hal/hal_com_phycfg.c rtl8188eu-linux-driver2/hal/hal_com_phycfg.c
< char file_path[PATH_LENGTH_MAX];
> //char file_path[PATH_LENGTH_MAX];
Once that is done, the tplink driver works perfectly.
Please update wily to use the new driver.
It may be worth informing the upstream kernel maintainer and Greg K.H.
about the new opensource driver for possible inclusion in the
upstream kernel staging tree in place of the troublesome driver that
is currently there.
