after upgrading my ubuntu to 11.10, my internet connexion became SO slow or it goes away for a couple of seconds.

It is a wireless connection, I have a dell studio 1525 and I have not install any additional driver

I know that it is a general question, but I really have not any more information.

Thanks

Same issue here with network controller: Intel Corporation WiFi Link 5100
Everything was working perfectly with previous versions of Ubuntu but after updating from Natty 11.04 to Oneiric 11.10 the problems with N-Channel started.

The following commands solved the problem.

sudo rmmod iwlagn

sudo modprobe iwlagn 11n_disable=1

Try browsing again and if there is an improvement, make this change permanent by creating an 'options' file:

gksu gedit /etc/modprobe.d/options.conf

and add the line

options iwlagn 11n_disable=1

Hope this will help.
