Both wifi bands (2.4Ghz and 5Ghz) worked fine in F28.
Moved from F28 to F30 using ‘dnf system-upgrade’ route. All went well, no errors, been using F30 for about 2 months.
Now, after some updates, F30 wifi will only connect to 2.4Ghz and does not find any 5Ghz Access points.
Laptop is a Dell xps-9370 with
Network controller [0280]: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter [168c:003e] (rev 32)
Checking for the available frequencies using ‘iwlist’ gives this;
iwlist wlp2s0 frequency
wlp2s0 32 channels in total; available frequencies :
Channel 01 : 2.412 GHz
Channel 02 : 2.417 GHz
Channel 03 : 2.422 GHz
Channel 04 : 2.427 GHz
Channel 05 : 2.432 GHz
Channel 06 : 2.437 GHz
Channel 07 : 2.442 GHz
Channel 08 : 2.447 GHz
Channel 09 : 2.452 GHz
Channel 10 : 2.457 GHz
Channel 11 : 2.462 GHz
Channel 12 : 2.467 GHz
Channel 13 : 2.472 GHz
Channel 36 : 5.18 GHz
Channel 40 : 5.2 GHz
Channel 44 : 5.22 GHz
Channel 48 : 5.24 GHz
Channel 52 : 5.26 GHz
Channel 56 : 5.28 GHz
Channel 60 : 5.3 GHz
Channel 64 : 5.32 GHz
Channel 100 : 5.5 GHz
Channel 104 : 5.52 GHz
Channel 108 : 5.54 GHz
Channel 112 : 5.56 GHz
Channel 116 : 5.58 GHz
Channel 120 : 5.6 GHz
Channel 124 : 5.62 GHz
Channel 128 : 5.64 GHz
Channel 132 : 5.66 GHz
Channel 136 : 5.68 GHz
Channel 140 : 5.7 GHz
Current Frequency:2.412 GHz (Channel 1)
That matches the AP I am using
wlp2s0 IEEE 802.11 ESSID:"wifi_2"
Mode:Managed Frequency:2.412 GHz Access Point: 46:D9:E7:03:CE:CB
Bit Rate=1 Mb/s Tx-Power=20 dBm
Retry short limit:7 RTS thr:off Fragment thr:off
Power Management:on
Link Quality=69/70 Signal level=-41 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:80 Missed beacon:0
So 5Ghz channels are shown.
Also, checking with
dmesg | grep 'ath\|firmware'

shows it is using the ath10k but there is an “unsupported HTC service id: 1536”
Any ideas on “unsupported HTC service id: 1536” ?
