Ubuntu won't connect to wireless internet on Acer Aspire 5730


For some reason, Ubuntu will not connect to a wireless network. It will occasionally connect, but I will open a page and it will not load. Soon after it would disconnect.

Any help is greatly appreciated.

A bit more info would help here.
What wireless card does your laptop have? If you do not know, post the output of lspci from the terminal. The wired ethernet and wireless interfaces should be near the end of the output.
Are the proper drivers loaded for your wireless device? If you do not know, post the output of lsmod in the terminal. Also post the output of:
Code:
sudo ifconfig
and
Code:
sudo ifconfig -a
from the terminal.
Assuming that Ubuntu recognizes your wireless device and has the proper drivers loaded and your wireless device is running ok, I would recommend using wicd instead of the
network-manager that is standard on Ubuntu.
To install wicd, first remove network-manager, thn install wicd:
Code:
sudo apt-get remove --purge network-manager network-manager-gnome
sudo apt-get install wicd
Then use wicd to configure your wireless.
Also, how is your wireless access point configured? Do you use encryption? If so, what type? Is it WEP? WPA? Post back with your wireless info.

And welcome to the LQ forums!

FWIW (remember, this come to you at no cost), for the past year or so, I've had much better luck with NetworkManager than I have with wicd. It might help for us to know which version of Ubuntu you're using.
