WIFI doesn't work after a fresh 4.0 install

[joss]

Hi to All guys ,

I have an Atheros AR9287 chipset.
I have a problem with the WIFI connection after a fresh  V4.0 install.
The problem is that after inserted the password to connect to DHCP server the system try to connect succesfully just for a second or Two and then disconnect. after this it tries to connect and disconnect infinitely .

I give a sight to system log ( but i'm not an expert ) and seem to see something related to WLAN hard blocked . I also don't know how to hold the messages in log view and stop scrolling.

Could any one give me a hand to solve this problem. Thanks

PS with V3.8 I didnt have any problem with WIFI. All worked fine.

Just as a guess.  Is your keyboard set up properly - language, country, Number lock  etc.  Try it out by typing a sentence, numbers etc etc in Libre to check.
all/keyboard  and all/language support

I had a problem with this.  Playing with System/Lite Tweaks Number lock  and rebooting solved the problem for me?


Afterthought.  Did you try Live LL4.0 on the machine- was the wifi working then?  did you check iso was complete.https://www.freecinema2022.gq/forums/installing-linux-lite/do-i-need-md5sum/msg40613/#msg40613

Hi newtusmaximus,
thanks for replay.

Yes, I just tried all that stuff with keyboard  but doesn't change anything.

I also noted that even when I started with a live 4.0 I had the same problem, but I thought  that installing he HDD version the problem gone away.

so , do you have any different suggestion to get rid of this "issue" ?

Check if you have a WiFi switch, either a toggle along the sides/top or perhaps an function key that enables/disables the WiFi radio.. =Example  Fn+F4

Can confirm from Terminal:
To verify if blocked run the commands

Code:

sudo rfkill list all

To unblock/enable all

Code:

sudo rfkill unblock all

Might be worth a try..

Just on the off-chance that your problem was the same as mine, I'm posting here, but odds are that yours is more complex than my user-oversight one. I had a difficult time trying to connect to Wi-Fi on LL 4.0 (but no probs on 3.8  ). That is, until I figured out NOT to go via the "Network" icon on LL 4.0, but instead to connect to Wi-Fi via the same place you used to on 3.8 - at the taskbar at the bottom. Then I was able to see the list of available networks and select mine and connect to it simply by entering the password.

Anyway, probably you have already tried this but I'm posting this in case it helps anyone else who is in the same situation as I was.

2: phy0: Wireless LAN

[member=6960]Vera[/member] , yes I just tried to set wifi connection from the task bar and setting network and password  with the results I write down in my post.

Do you all think  could be a good idea to reinstall from scratch , I mean to format the full HDD?? even thought I still seen the problem in the live 4.0??

Hi firenice03,
sorry, where did you see that wifi is off ??

0: acer-wireless: Wireless LAN
  Soft blocked: no
  Hard blocked: no

I don't see anything. It seems to me that it is just not hard blocked ... Am I wrong. ??

In any case I'll try  with  sudo rfkill unblock all  ...and I see whats happens

[firenice03]

I saw..

2: phy0: Wireless LAN
  Soft blocked: no
  Hard blocked: yes

What happens when unblocked - may need to unblock with a keystoke(Fn+Fx)..
Guessing you have 2 WiFi cards an internal and a USB??


Also you may want to run the below commands and post the output...

Code:

lspci

Code:

inxi -Fxz
