rtl8192se very slow

I reinstalled arch after switching to an ssd, thus it used to work in the past without problems.
With

cat /etc/modprobe.d/rtl8192se.conf 
options rtl8192se fwlps=N ips=N swlps=N swenc=Y

I am getting very high speed, but only for a limited time. Not setting these options results in slow speed all the time. If I reconnect manually, or if I reload the module using

sudo rmmod rtl8192se; sudo modprobe rtl8192se

it is fast again for a limited time.

Additional information:
lspci -k:

Re: rtl8192se very slow

I'm basically clueless, but my rtl8723be works fine with the same options as yours and

disable_watchdog=1

so you could give it a try. Which network manager are you using? Have you tried using another one?

systemctl list-units --state=active | grep net
