Fresh install and no WiFi connection on Acer Aspire5745g laptop

General system Newbie
21

I never use the preformatted text selection. I usually insert 3 tilde ~~~ or 3 back ticks ``` before and after my output that i post. I think the OP is selecting the preformatted text after the fact.

Edit: Do you not have to select it first before entering info?

22

You could.
Or highlight the text and click </>.

23

Try this:

sudo wpa_passphrase SSID PASSWORD > /etc/wpa_supplicant/wpa.conf

Replace SSID and PASSWORD with the real values.

Then:

sudo wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/example.conf

24

This is so strange to me. I’ve never ever had to do anything with wpa supplicant in any installations. :thinking:

25

Prior to this installation I have used a previously released ISO of EOS and was able to use WiFi as a “liveuser” on this Acer laptop and with the same WiFi network and it’s credentials.

26

Me either!

I replace it with iwd :smile:

27

Try what @pebcak suggests and see.

28 
after entering `sudo wpa_passphrase SSID PASSWORD >  /etc/wpa_supplicant/wpa.conf`
with actual data the sytem returned with 
"bash: /etc/wpa_supplicant/wpa.conf: Permission denied"

Also, I am using WEP key...
29

Ok, thank you.

Why are you not using wpa wpa2?

Edit: Is your router not set to use wpa wpa2?

I forgot to select the text. Still learning… :slightly_smiling_face:

32

Sorry, I should make some corrections:

  1. sudo touch /etc/wpa_supplicant/wpa.conf

  2. sudo su

  3. wpa_passphrase SSID PASSWORD > /etc/wpa_supplicant/wpa.conf

    replace SSID an PASSWORD with real values

  4. wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa.conf

33

Long story. I may be able to change it later. I need to use WEP for now.
And, I was able to use this same WEP key with a previous EOS release in a “liveuser” session.

34

Okay… it’s just not as secure.

35

I entered the commands:
[user@Aspire5745g ~]$ sudo touch /etc/wpa_supplicant/wpa.conf
[sudo] password for user:
[user@Aspire5745g ~]$ sudo su
[root@Aspire5745g user]# wpa_passphrase SSID WEPkey > /etc/wpa_supplicant/wpa.conf
[root@Aspire5745g user]# wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa.conf
Successfully initialized wpa_supplicant
wlan0: CTRL-EVENT-SCAN-FAILED ret=-16 retry=1

36

Yes

37

Code tags?

38

If you feel confident you could replace wpa_supplicant with iwd and see if you have better luck.

If you don’t, don’t!

Good luck!

And :wink:

Highlight the entire pasted text and then click on </> to format.

39

I would give this a try for sure if it were me. :wink:

Ok, I will try that tonight. Thank you guys!
