Title:
slow wifi (atheros [ath9k] drive
I hate the Atheros wireless cards. I've met this problem on so many
laptops. Anyway, one of my older laptops have a "Intel Corporation
Ultimate N WiFi Link 5300" (as reported from lspci -v). It seems this
does not use the ath9k driver, so the reported workaround does not work.
However, this workaro
Ok, just for you to know, during these days I tested with the following
releases:
Oneiric Beta 1 -> The problem is there
Natty -> The problem is there
10.10 -> Here it works fine!

Sorry for posting this often, but for my USB device the solution turned
out to be even simpler than what I described before:
(1) Type into terminal:
gksu gedit /etc/modprobe.d/blacklist.conf
(2) Add those to lines to the file and save
blacklist arusb_lnx
blacklist ar9170usb

Sorry, I forgot one important point:
BEFORE running wget in point 1) you will need to change directory to

So... I finally resolved the issue effectively without any remaining
restrictions. But in order to do that I made a rather 'radical' move...
I installed the carl9170 firmware and compiled the carl9170 kernel
module from compat-wireless package. (This might take about 10-15
minutes of your time)

Thank you very much Terry for the workaround and for sharing your
experience with us.
Unfortunately it did NOT help in my case, even though I tried this
little trick with all atheros kernel modules I could find.
It's quite disappointing... especially that this regression does not
seem to draw muc

Thanks for the workaround, I just tried it. Using G instead of
N-standard resolves it. Nevertheless, I like having a fast N wireless
connection...
What helped me with this issue was to use the old kernel that was
installed in ubuntu 10.10 before the upgrade (I think it was linux
kernel 2.6.35). Bu
