Hi Guys,
I have several serious regressions since the rtl8187se staging driver
was merged into the generic rtl818x_pci driver with kernel 3.15.
With my Netbook for travels I have now...
1. Wireless transfer rate dropped seriously from about 2.5 MByte/s
crushed down to 700 kByte/s in Linux kernels 3.15 and 3.16!
2. Signal rate always says 15% even if I'm right next to the WLAN
router! No possibility any more to determine which WLAN router is the
strongest (most nearby) in hotels. Weaker WLANs in neighborhood seems
not to be shown also because of this weakness.
3. The device can not be switched off any more by keyboard or plasma-nm
and is always switched on - security risk!
All these regressions were introduced with 3.15 and the merge. And this
with all this talking that staging drivers would be as bad as hell. Here
it's vise versa.
I'm now forced to go back to 3.14 - and the staging driver for rtl8187se
- where I only can find an early 3.14.4 on my private local copy of OBS
stable kernels.
There, with 3.14, everything is back to normal!
How to address this or can anybody offer a port of the earlier staging
driver of rtl8187se from 3.14 for the newest 3.16?
I like to test the newest kernels but this seriously prevents me.
BTW, I'm not the only one facing these problems:
