This question already has an answer here:

I can connect to my house's wireless network just fine, but when I'm connected I can't browse the web. Firefox starts connecting to a site and then just poops out. This doesn't happen on my roommates' computers (running Windows) or on our 3DSes, so I know it's just my laptop.

(Edited to remove irrelevant information)

This other user's answer solved my problem.

I would post this as an answer, but the site keeps converting it to a comment. Thank you for all the suggestions, though!

Okay, I've done that. – A.J. Oct 26 '13 at 3:49
Done. (Do I need to comment when I've done it, or can you track edits?) – A.J. Oct 26 '13 at 4:03
You sure the password is correct and that is your router IP? If you are sure, then run sudo dhclient wlan0. And no, any update has to be commented or I don't get a message. – Braiam Oct 26 '13 at 4:10

You can open this file:

sudo gedit /etc/modprobe.d/ath9k.conf

And add this line:

options ath9k nohwcrypt=1

Check if this works:


It may be this bug:

Let us know.

Thank you, but that doesn't seem to have made any difference. To clarify, my problem isn't with the wireless connection itself. It connects just fine. I just can't browse the web while connected. – A.J. Oct 26 '13 at 16:28
