Comment # 4
on bug 910054
from Eric Benton
I just got an update that takes me from using kernel 3.18.0-1.gfc82a91-default
to 3.18.0-2.g99a9f76-default.
When I rebooted the wifi speed was again slow at about 4.3 mbits/s using iperf.
Installing the attached drivers and reboting bumped me back up to over 65
mbits/s
modinfo on the rtl8732be.ko for each kernel doesnt show a version so i cant say
much in that regard. (a version string of some kind ought to be mandatory for
drivers so you can quickly tell what you have via modinfo)
I can make my laptop accessible for inspection or test sw if you want. There is
nothing too important on it at the moment. Lenovo G50-70 with core-i7
I dont know if this is useful but here is some data. How do i know if I have
the latest (or correct?) FW. I remember messing with that early on due to the
wireless didnt work AT ALL when i recieved the laptop and intially installed
OpenSuse 13.1 (I was wrong in my above posts, i just checked and it was
OpenSuse 13.1 not 13.2 according to /etc/os-release)
