Unable to get wireless connection working

Can you give the output of:

sudo lshw -C network; lsb_release -a; uname -a; sudo rfkill list; dmesg | grep -i firm

Thanks

We only have part of the response here possibly because you thought grep was a separate command.

Open a terminal (CTRL+ALT+T) and try again copy and paste its all one command

--------------
sudo lshw -C network; lsb_release -a; uname -a; sudo rfkill list; dmesg | grep -i firm
------------

Sorry for my lack of understanding. The full string certainly yielded very different results.

sudo lshw -C network; lsb_release -a; uname -a; sudo rfkill list; dmesg | grep -i firm

Did you have the adapter when you ran the command? Can you also give the output of:

lsusb

Thanks

Sorry, doing too many things at once.

Results are below. First pass is from the long string followed by lsusb with the Netgear adapter plugged in. There is no corresponding software loaded as the install CD doesn't have any Linux format files that I can find. The Netgear website doesn't give any indication that it will work with Linux OS. This would be my preferred choice if it would work.

Second pass is the long string followed by lsusb with the mini adapter (dongle) plugged in(usb 802.11N 150 mbps). The install CD has a Linux zip file which I copied to the laptop and extracted. Beyond that I didn't know what else to do.

I noticed in the configuration results "driver=tg3" notation. That reminded me that when installing Lubuntu, there was a message about non-free firmware that I needed "tigon/tg3.tso.bin". I have not tried to get that firmware.

hope this helps

With the dongle fitted your system appears to be recognising it as a wifi interface can it see your network?

To test open a terminal and give us the output of

ifconfig; iwconfig; sudo iwlist scan

It can see the Verizon MiFi card. That's all I'm trying to get to. I don't have any other network. Here's the results:

The wifi appears to be working but not finding a network. Is your wireless router tuned on and reasonably close to you computer?

Not that I don't appreciate all the effort but I think you got lost in the weeds this time. I believe I answered that when I submitted my original question at the top of this string.

Yes, my wireless Verizon card is turned on, 5 feet away and working fine. That's what I'm using with this laptop. The problem laptop (Dell Lattitude D600) is right beside me. It finds the network, calls it by name but craps out on the password. Never do I get a message that the password is incorrect. It just cycles to the "enter password" screen over and over every 30 seconds or so.

I know it was probably a stupid question but I had to ask to be sure. Its unusual for

sudo iwlist scan

to find nothing I can usually see 5 or six networks in addition to my own but I guess it depends on how many of your neighbours have wifi and how close they are.

If the laptop that works is linux can you run the following command please it will tell us what networks it can see.

sudo iwlist scan

For Windows 7 the equivalent command is

netsh wlan show all

Oh, no problem with the question. I'm sure I'm not the only newbie you're trying to help. This laptop is running windows 7 (Compaq CQ60-423DX). The results of the command are below. A little more info though......

I live out in the country so to speak. One neighbor's wi-fi network shows up sometimes but nothing else. The Verizon MiFi 4GLTE card is my only access to the internet so I know it's working fine. As I take this card with me when I travel, I have it set to require password authentication. As you'll see by the command results, this computer connects using WPA2-personal authentication. I have the Dell (running LUbuntu) set to WPA WPA2 Personal with password required. It always sees the network, knows the name (SSID)and tries to connect. I enter the password, it spins for 30 seconds or so and asks me to enter it again. Doesn't give an error though. Just acts like it's coming to the password screen for the first time. Once in a while, it actually says the connection has been established. But any website I try to reach yields the same error. Something like Server not found, DNS server name not resolved. I don't currently have that in front of me to be more specific but you've seen the error before. Now for the results.......and thanks for continuing to work with me.

I cant see anything wrong here it should work. I suggest you report a bug. I'm out of suggestions
