iwlist scan | egrep -i 'ssid|quality'












0














Like many people with a Realtek RTL8723BE Wi-Fi controller I have issues catching Networks. I followed the answer from here:



https://askubuntu.com/a/1079892/898693



But at point 7,when entering:

iwlist scan | egrep -i 'ssid|quality'



I get following output:



```
enp3s0 Interface doesn't support scanning.



lo Interface doesn't support scanning.



```



So my question is, if there's another way arround to test which antena I should use?



Thanks for the help!

    Have you successfully installed Wi-Fi driver? enp3s0 is generally logical name of the Ethernet Interface. You can check logical names of network adapters using sudo lshw -C network | grep 'network|description|logical name' and indeed Ethernet interface doesn't support scanning. What is the output of rfkill list all? Alternatively you can also use nmcli dev wifi.

  • So, I moved closer to the router and I got following output: [enp3s0 Interface doesn't support scanning. lo Interface doesn't support scanning. Quality=38/70 Signal level=-72 dBm ESSID:"BO_Oficina"]

Quality=38/70 Signal level=-72 dBm ESSID:"BO_Oficina"] The difference between the two antennas in minimal, -72dBm and -78dBn. Using the network scanner of my MacBook position next to the HP labtop gives me -42dBm. Is there way to improve reception of the HP or should I just buy a USB Wirless adapter? Sorry about not be able to properly format the output. Tried with ```vbut its not working.

  • changing value of ant_sel generally works. I generally refer this question while installing driver for the same. You can also refer linked duplicates.
