list of available WiFi networks - missing SSID 2,4Ghz

Postby korbielow » 2020-03-31 20:04

Hello!
I have a problem. I do not see my WIFI 2,4Ghz network. I only can see tplink_5G. My router shares two types of network SSID tplink_5G and tplink_2G.
Can someone help me ?
I have Network controller Broadcom Limited BCM43224

Code: Select all
root@debian:/home/rafal# cat /etc/debian_version
10.2
root@debian:/home/rafal# lspci | grep Network
00:19.0 Ethernet controller: Intel Corporation 82577LM Gigabit Network Connection (rev 05)
02:00.0 Network controller: Broadcom Limited BCM43224 802.11a/b/g/n (rev 01)

root@debian:/home/rafal# iw dev wlp2s0 scan | grep SSID
   SSID: tplink_5G

afal@debian:~$ nmcli dev wifi
IN-USE  SSID       MODE            CHAN  RATE      SIGNAL  BARS  SECURITY
*       tplink_5G  Infrastruktura  36    270 Mb/s  97      ▂▄▆█  WPA2

Which driver is your Broadcom card using?
Code: Select all
lspci -k | grep -A2 Broadcom

Would start at the router. Sounds like you've been fiddling around in it's settings? Does the 2.4ghz access pt show up in other devices(like your smartphone)? Other things, might check any uefi-bios settings available on that system, related to this type of thing. Though really doesn't make sense.
