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. wlp3s0 IEEE 802.11 ESSID:"Aaadamun: 7+60" Mode:Managed Frequency:2.462 GHz Access Point: 38:A4:ED:4B:A5:C5 Bit Rate=1 Mb/s Tx-Power=20 dBm Retry short limit:7 RTS thr:off Fragment thr:off Power Management:on Link Quality=61/70 Signal level=-49 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:107 Missed beacon:0 3. My copmputer is very new: DELL XPS-8930, so maybe the company have not released driver fot it.

I think an updated firmware is needed.
