unable to set 5 GHz band on pi 4B.

[dineshlama]

I am following https://www.raspberrypi.org/documentati ... s-point.md tutorial to set pi 4B as wireless access point with 5 Ghz band. But when i change the hw_mode=g to hw_mode=a as described in that tutorial to get 5 GHz bank wifi. and than enable and start it.with commands:

Code: Select all

sudo systemctl unmask hostapd
sudo systemctl enable hostapd
sudo systemctl start hostapd

and than i check it info with iwconfi it don't shows that it is 5 GHz:

Code: Select all

wlo1      IEEE 802.11  ESSID:"Pi4B"  
          Mode:Managed  Frequency:2.442 GHz  Access Point: DC:A6:32:75:E5:FB   
          Bit Rate=54 Mb/s   Tx-Power=15 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:on
          Link Quality=70/70  Signal level=-31 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:52   Missed beacon:0

What is the problem? Is this related to my laptops wifi card?

You've set it to channel 7, which it's assuming is the 2.4GHz channel 7. Pick a 5GHz channel number (likely 32 <= x <= 48 for most indoor use in most regions).

What channel should i give than to make the data rate higher? will any value in that range will work same?

'iw phy' will give you the list. Look for the Frequencies section of Band 2.
