Can't connect wirelessly, but it says I am?

[YMS_1975]

Yes, indeed, you have an IP address. Addresses in the range of 10.42.x.x are generally used for ad-hoc, that is computer-to-computer arrangements. Is that what you intended? No?? Is that the range used by other computers on your network? I suspect they are typical home network addresses, something likke 192.168.x.x.

Please right-click the Network Manager icon and edit connections. Select Wireless and go through each tab and remove, delete, purge all extra settings except one. Be sure Mode is set to infrastructure. Please see attached. Close everything and tell us if Network Manager finds and connects to your network as expected. It may take a reboot.

I did everything as you explained, but it's still not connecting. What else can I try?

but it's still not connecting.

Meaning what? Does it see networks in the dropdown? When you select yours, does it try? Does it ask for your password and time out? What does it do and not do??

Sorry for not providing adequate information. Yes, it does show my network. I am typing in the correct password.

Then it attempts to connect the network, but it won't connect. Instead, a dialog box appears asking me for the password (again).When I type in the password, it continues to search, but still won't connect.

Let's see what Network Mangler is doing all this time. The Broadcom STA driver is usually pretty solid.

cat /var/log/syslog | grep etwork | tail -n20

Please run and post that immediately after you tried and failed to connect. Be sure any ethernet cable is detached as NM will disable wireless in favor of faster and more secure ethernet if available.

So it gave up after 20+ seconds trying to connect, maybe interference? Try
sudo iwlist scan |egrep -i "ssid|quality|channel:"
and see what channel other access points are on and how strong they are.

I'd like to be sure no conflicting drivers are loaded and that wl is most appropriate for your device:

lsmod
lspci -nn | grep 0280

[besial]

You could try to connect manually...
Save this to a file named 'wpa_supplicant.conf'

# WPA-PSK/TKIP

ctrl_interface=/var/run/wpa_supplicant

network={
    ssid="your_router_name_here"
    key_mgmt=WPA-PSK
    proto=WPA
    pairwise=TKIP
    group=TKIP
    psk="your_wifi_password_here"
}

...Then run your wpa_supplicant in debug mode...

wpa_supplicant -iwlan0 -c ./wpa_supplicant.conf -d

*NOTE* I don't think it's interference, as I am currently in the same room as the Dell Studio 540 desktop I'm having problems with, but on a laptop running Ubuntu 12.10 and I can connect wirelessly just fine with that laptop.

So I think the desktops connectivity issues are something else. I noticed that under "Additional Drivers", it lists the Broadcom Corporation: BCM4321 802.11 b/g/n and directly below that it states : "This device is using an alternative driver".

There are 2 radio button options below that (Option #1 is selected);

1) Using Broadcom 802.11 Linux STA wireless driver source from bcmwl-kernel-source(open source)

2) Do not use the device.
