I'm relatively a newbie and don't have much experience with linux. I'm unable to connect to my broadband connection using a wi-fi modem, though the conection works fine with a LAN cable. Details:

Hardware: Toshiba Satellite L650
OS: Ubuntu 11.04
Broadband: Bsnl
Modem: WA1003A

PS: My modem has been configured for bridge mode.

Please guide with step-by-step instructions.
Help appreciated.

Blacklist the following module:


echo "blacklist brcm80211" | sudo tee /etc/modprobe.d/blacklist-brcm80211.conf
and reboot. Does you router accept new clients (MAC-adress filter)?

I executed that code and re-booted my system. The Wireless connections are now visible and I can establish a connection with my modem.

As for the router accepting new clients, I've no idea.

Help appreciated so far. Now the second problem is that I use a username and password, provided by my ISP, to connect to internet... Where do I do that???

Go to your router interface and establish a PPPoE-connection

I just re-booted and the list of wireless connections has disappeared again.

+1

If you have trouble see here http://www.calcutta.bsnl.co.in/dataoneinstall/menu.html

it is your ISP, a link to your modem and a zip file download for Linux

And can't I configure it with a bridge type connection, so that I dont have to store my username and password on the router??

@haqking: Thanks for help. But still doesnt solve the problem of ubuntu not detecting wireless networks available.

Make it a permanent connection from network manager.

Plus they dont always show up staright away until your keyring is unlocked, how is your keyring setup ?

I've no idea about keyrings... I haven't set up any yet, so I'm guessing its unsecure.

Okay, I'm lost here. Lets take it one step at a time.

The first and foremost problem is getting my system to detect wireless networks. As of now it does not detect any wireless connections available.
