1. I installed Kubuntu 18.04 beta-1, after it was released, and from first day,
I always have been getting:
Bit Rate=1 Mb/s on 2.4G, and
Bit Rate=6 Mb/s on 5G.
2. I did test latest upstram kernel (v4.16), but my computer did NOT show up
login screen (sddm), but from command line I were getting same bitrate (1 Mb/s):
iwconfig
enp4s0 no wireless extensions.
lo no wireless extensions.

3. My copmputer is very new: DELL XPS-8930, so maybe the company have
not released driver fot it.

** Side note **
Despite slow bitrate I were able to get speed up to (954 kB/s) ( I saw it when
downloading update i.e. apt update)
** Tags added: kernel-bug-exists-upstream
** Summary changed:
- QCA9377 WIFI does not work full speed
+ QCA9377 WIFI does not work full speed - runs at lowest biterate 1Mp/s
** Tags added: apport-collected
** Description changed:
I'm using Ubuntu 18.04, development branch, and I have
QCA9377 802.11ac Wireless Network Adapter
When I connect it to WiFi hotspot in 2.4G mode I will get only 1MBps, and
When I connect it to WiFi hotspot in 5G mode I will get only 6MBps.
I think an updated firmware is needed.
