I installed Ubuntu on my notebook yesterday. All right except wi-fi connection.

I found wi-fi network (based on D-link dir-300) and connected. But it works too slow and disconnect every 1-3 minutes. You can say that maybe problem is in connection but on my notebook i have windows 7 and ubuntu 10.10 and in windows i have no such problem. Windows works well with wi-fi. But Ubuntu...

I have:

DSL internet connection. modem is connected to router. Router connected with desktop by wire and with notebook samsung R528 by wifi. Router - D-link DIR-300.

Rusult of lspci -k is:

Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)
    Subsystem: Foxconn International, Inc. Device e025
    Kernel driver in use: ath9k
    Kernel modules: ath9k

Thanks for any help!

P.S.

I wrote this message from Windows 7. I edited this message from Ubuntu but i see that internet works more slower than in Windows 7.

Firefox on Winddows 7 loads this page in ~ 2-3 seconds Firefox on Ubuntu 10.10 loads this page in ~ 20 seconds

Kernel 2.6.39 completely fixed the issues with the ath9x driver for me in 11.04 (Natty). I can do high-load transfers without issue. Comment #8 on "wlan (AR928X, ath9k) slow since upgrade to natty" contains instructions on how to get this kernel from a PPA. I did an apt-get install rather than a dist-upgrade, but either one should get you the new kernel. Here's what I did:

sudo add-apt-repository ppa:kernel-ppa/ppa
sudo apt-get update && sudo apt-get install linux-generic-pae

If you're using a 64-bit kernel, I think the package to install is just "linux-generic". Or just follow the instructions right in the bug (use apt-get dist-upgrade -y).

Also possibly related:

After upgrading to linux 2.6.39, changing the ath9k driver config (as suggested in Why is my internet so slow with an Atheros wireless card?) is not necessary.

Hope this helps!

I have been having this issue with Atheros for a long, long time. I have even given up on Ubuntu for some time (my Windows connection worked fine), but I found out that switching from Unity to Gnome was enough to solve the problem. I don't know how to explain why this is so (new user), but it just works.

Maybe you want to check the question I opened myself about this some months ago: Is the wireless driver from Live USB different from the standard install?

Best of luck.
