[Bug 1525254] Re: The r8188eu driver shipped with wily is broken, new working driver exists
** Description changed:
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 REGRESSION.
- Furthermore, on the tplink driver the *source* or a driver that works
+ Furthermore, on the tplink website the *source* or a driver that works
fine is available:
http://www.tp-link.us/res/down/soft/TL-WN725N_V2_150911.zip
Porting to a format consistent with the pristine kernel has been done,
see
https://github.com/lwfinger/rtl8188eu/issues/152
and

driver.zip?dl=0
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

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.
