Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I recently installed Ubuntu onto my Dell Inspiron 1545 laptop.

I can connect to the Internet via Ethernet, but wireless won't work. The prompt to put in the wifi password pops up, but when I put in the password, it simply says connecting and the prompt for the password comes back up! The prompt will come back up every two or three minutes, but the same thing happens.

I've tried to install drivers using Windows Wireless Drivers, but I can't seem to figure it out. My wireless card is an Atheros AR928X. This is my first time using Ubuntu.

Here is the output of the commands I've been asked to run:


1- Output of lspci -nnk | grep -iA2 net

@edwin I do not know how to make the commands more readable in comments, I have tried before and this is the best I came up with. –  Wild Man Aug 7 '13 at 21:32
    
Sorry, should I enter the entire "sudo cat /var/log/syslog | grep -e ath -e firmware | -e wlan -e wpa -e etork tail -n45" Or is each line a command that should be entered? –  user182232 Aug 7 '13 at 23:18

Please copy and paste the commands for accuracy one line at a time:

echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf

sudo modprobe -rfv ath9k

sudo modprobe -v ath9k

Also it would be best to set encryption in the router to just wpa2 if you have that option by entering 192.168.0.1 or something very similar to those numbers in your web browser while having an ethernet connection, you may have to look at the documentation for your router for the exact numbers to enter.

Also try channel 1 or 11 in your router.

You can google the documentation for your router. Please set your wireless settings in network manager to match the screenshots.wireless settingswireless settings

You should also remove your connection in network manager and reset your router then reboot your computer.

Cant seem to find the router documents at the moment. Will comment if found. (Thanks for the help btw) –  user182232 Aug 7 '13 at 21:30
    
I would run the commands and see if that makes it connect then you can look up router documentation if needed. –  Wild Man Aug 7 '13 at 21:34
    
Wireless still not connecting. I still can't find the documents. Any other suggestions? –  user182232 Aug 7 '13 at 21:59
    
I've gone through the entire answer, step by step, but the wireless won't connect. I think here is where I admit defeat. Thank you all, especially Wild Man,for all the help. I think I have to crawl back to Windows now... Again, thanks for all the help. You guys were awesome! –  user182232 Aug 8 '13 at 17:56

I had this same issue with a RealTek RTL8188EEE wireless card and Ubuntu 13.04. The quick solution was to just put in the IP of my Wireless Router, then change it from AES to TKIP-AES. This kept the other systems on my wireless happy, and suddenly Ubuntu took the password and connected me with a reported 72Mb/s connection speed.

I couldn't do too much more since I was running from the DVD, making sure it works before I install. I had seen suggestions of doing NDISWrapper and then rebooting - not gonna help with the DVD.

Hope this helps anyone else looking. Probably too late to help the original person posting, but maybe it will help someone else. If you can't do TKIP-AES, try going from AES to just TKIP. That was suggested in another forum as well.

Make sure you have wireless-tools installed via sudo apt-get install wireless-tools

This will provide a better GUI to connect to existing wireless networks.

Try pinging any site, local computer or not, to test if it is working. You may get a specific error, which may mean that some of the settings are off.

When put into the terminal, it comes back saying that the wireless tools are already the newest version. –  user182232 Aug 7 '13 at 22:10
    
What Ubuntu version are you using, and what desktop environment? (Unity is default, if you just installed) –  Mobo Aug 7 '13 at 22:20
    
Version 12.04 LTS. I am assuming that the desktop environment is "Unity" as I don't recall making any changes like that. –  user182232 Aug 7 '13 at 22:23
