Slow wifi internet ubuntu 12.04.02

[parantonis]

Hello everybody

Im a new linux user and the first time I use ubuntu in my laptop I face this problem.
When I connect to my home wireless network my internet connection speed is like a PSTN.
I try to give interrnet to my computer via ethernet and it works very fast. Please be more
analytic if you can because as I mention before i'm a new Linux user.

Laptop : Acer Aspire 5738
 Network controller [0280]: Intel Corporation WiFi Link 5100 [8086:4232]
Subsystem: Intel Corporation WiFi Link 5100 AGN [8086:1201]
Kernel driver in use: iwlwifi

Thank u in advance.

Hi,

deactivate the N-mode of the driver (bug):

echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
sudo modprobe -rfv iwlwifi
sudo modprobe -v iwlwifi
