Can't connect to Wireless 13.10

Question

I am having problems with my wireless connection using ath9k, I cannot connect to any wireless network. I can connect to the wireless network fine on windows 8.1 but when using ubuntu gnome I have no luck.

Any Help Appreciated.

OS: Ubuntu Gnome 13.10

What has been tried so far:

sudo modprobe -r ath9k

sudo modprobe ath9k nohwcrypt=1

sudo modprobe -r brcmsmac

echo "blacklist brcmsmac" | sudo tee -a /etc/modprobe.d/blacklist.conf

Wireless Card: TP Link TL-WDN3800

Everything in those outputs seems fine. What exactly are you experiencing? Can you see a list of wireless networks when you click on the wireless symbol on the top right? Can you click and connect to your desired network? Do you enter the password correctly if it asks you for one? Or does it repeatedly ask you for a password even after you enter it correctly? Or do you connect successfully, but can't access the internet? What exactly are you facing? — Alaa Ali, Jan 05 '14 at 16:45
I can see wireless networks, I click to connect enter a password and it does not connect. I'm 100% certain the password is correct. It does not repeatedly ask me for a password, It does not connect at all, says "connecting" then nothing. I also tried connection to a wifi hotspot on a phone and the same thing happened. — Jamie, Jan 05 '14 at 16:50
Try executing sudo modprobe -r ath9k, then sudo modprobe ath9k nohwcrypt=1, then try to connect. — Alaa Ali, Jan 05 '14 at 16:59
Ok I will test this now, may take 10 minutes for me to reply, have to reboot etc. — Jamie, Jan 05 '14 at 17:00
Hey, just wanted to say thanks for the help so far. I executed the commands above but still cannot connect. — Jamie, Jan 05 '14 at 17:17

Execute:

sudo modprobe -r brcmsmac

Then try to connect. That should work.

If it does (or even if it doesn't) work, execute the following:

echo "blacklist brcmsmac" | sudo tee -a /etc/modprobe.d/blacklist.conf

Then reboot.

Thanks for the reply, going to try this and will post the result when I finish. – Jamie Jan 05 '14 at 18:00
I executed the first command then tried to connect, no luck. executed the second command rebooted but still getting the same issue. – Jamie Jan 05 '14 at 18:13
Oh man. I'm out of ideas. Edit your question to include what you did so far (so others don't miss anything). Also, include the output of lsmod | grep -E 'ath|brcmsmac' and dmesg | grep -E 'cfg|ath|wlan'. This should help others in troubleshooting. If the output of the second command is huge, paste it in http://paste.ubuntu.com and give us the URL. – Alaa Ali Jan 05 '14 at 18:18

Try using

rfkill list all

in the terminal. It will bring up something that looks like this

`0: phy0: Wireless LAN Soft blocked: yes Hard blocked: no 1: hp-wifi: Wireless LAN Soft blocked: no Hard blocked: no

If any of them come back saying yes userfkill unblock all Hopefully this fixes the issue
