11.10, wifi card Atheros AR928X & driver ath9k

[palimmo]

Hello!
I have a problem with PB Easynote TJ65 and Ubuntu 11.10.

The wifi connection is slower compared to 11.04.... annoying during live video streaming (TV, etc...)

Could you help me, please?
Here some info:

As suggested here

I tried to disable the N channel from the router and reconnect.

But nothing...

[palimmo]

SOLVED!!!


Simply....

Completely removed the following packages:
network-manager

Removed the following packages:
network-manager-gnome

Installed the following packages:
python-wicd (1.7.0+ds1-6)
wicd (1.7.0+ds1-6)
wicd-daemon (1.7.0+ds1-6)
wicd-gtk (1.7.0+ds1-6)

What's the real reason?? :O

[varunendra]

Yet another mysterious solutions I've seen I would like to hear a confirmation regarding its consistency.

As for the reason, I remember having read something somewhere sometimes ago , but despite wasting last 30+ minutes trying to search it back, I couldn't find it. IIRC, it was something about NM expecting something from the driver which, due to its immaturity, the driver didn't have. - resulting in communication/control failure. In contrast to NM, wicd is simpler and didn't expect that 'reply' (or whatever it was) from the driver - resulting in consistent control. However, it also implies that wicd can not make use of that 'advanced' feature in those drivers which have it. But it doesn't matter for you since you don't need that 'feature' (heck, I don't even remember what that feature or functionality was actually).

I'm sure this explanation must have made things clear as mud . I wish some wicd/nm developer sees this and explains the difference.

Just thought I'd add that I was also having problems with a slow internet after my upgrade from 11.04 to 11.10 on a Thinkpad T60, and replacing network-manager with wicd did the trick for me too.

Since I am having the same problem, and I am a complete noob with ubuntu, I was wondering how to removed and installed those packages.

Thanks!

You can do so using Software Source (remove "Network Manager" and install "wicd"), or you can do the same with commandline by opening a terminal and entering these commands (wait for the first to finish before entering the second one):

sudo apt-get install wicd
sudo apt-get purge network-manager

Do not run the second command first as it will leave you in a disconnected state and you won't be able to install wicd with the first command. (the same thing also applies in GUI, so make sure to install wicd first, then remove NetworkManager)
