Re: Realtek r8822be kernel module does not negotiate 802.11ac connection

Larry,

I tried using iw but it gives the same reading for bit rate.  In regard
to the firmware, it was not installed via "make install" so I did it
manually.

Sincerely,

Larry,

Sorry about all these extra replies.  Shortly after I sent my last
message my access point started recognizing the connection as 802.11ac
with PHY Rate / Modulation Rate of 866.6 Mbps.  What is somewhat
misleading is the information reported by iwconfig (see bit rate below).

$ iwconfig wlo1
wlo1      IEEE 802.11  ESSID:"XXXXXXXXXX-5G"
           Mode:Managed  Frequency:5.22 GHz  Access Point:
xx:xx:xx:xx:xx:xx
           Bit Rate=6.5 Mb/s   Tx-Power=23 dBm
           Retry short limit:7   RTS thr:off   Fragment thr:off
           Power Management:on
           Link Quality=70/70  Signal level=-40 dBm
           Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
           Tx excessive retries:0  Invalid misc:11   Missed beacon:0
The utility iwconfig is obsolete and not exactly up to date with the
latest in wireless. I am not an expert on iw, but I think you want 'iw
dev wlo1 link'.

I am wondering about the missing firmware stage. Had you not done the
'sudo make install' step, or did that step fail to install the firmware?
