View Full Version : [ubuntu] Help...I can only -half- connect to my router!

This all started yesterday when I had to change the WPA password for my WiFi Router. Before that everything worked fine. It also works fine right now if I use Windows. It's just in Ubuntu I'm having problems.

What happens is this. I right click the wireless Icon up at the top and "enable wireless". I then left click and get the list of networks in range and select mine. Of course since its the first time it prompts for the password. (I deleted my old one by going to "edit wireless networks" and removing it).

I enter my password and the little circle thingy goes round and round and the bottom dot goes green but not the top. This goes on for a while and eventually prompts for the password again. And so on.

Can someone tell me whats going on and how to resolve it?

Thanks

Oh BTW I should point out if I take my laptop to a public unsecured WiFi location I can connect just fine. So its not a problem with my wireless as such. It seems to be something it accepting my password?

Thanks

Can't help you, but I have a similar problem. Your remark that you can go to Starbucks or wherever and connect intrigues me. Last night I installed a new HD and loaded dual-boot XP/Hardy on a laptop. Like you, I cannot connect to my home network 2wire411 (from Hardy), but I can see it, select it, key in my wep key 0360663701 and watch the spinner for a few seconds until it asks for my wep key again. This, in spite of the fact that the wep key works for computers in the house on Intrepid, XP (the dual-boot laptop with the problem), and Vista (the computer I'm typing on right now). I haven't taken my laptop to Starbucks yet, so I don't know whether it works there, but it probably will.

Would you do me a favor, and report what you get when you query
sudo lshw -C network

This might be helpful to someone who might come to our rescue, but my experience is that once a thread gets a few hour old nobody pays attention to it.

Here's what I get (below); the wireless network shows up in the last 6-7 lines.

This happened to me. I had to change my wireless security to 128 bits. Don't type your passphrase btw, use the keys.

I've just resolved it. Not quite sure why though. Near to me is a weak unsecured WiFi network. For some strange reason that was screwing up my access. Its not channel issue though because it worked before and does now again. I went to "edit wireless networks" and deleted the unsecured one. Then went and tried to connect to my router and entered the password prompt and in I went just fine. Now everythings fine again and I can use mine or for that matter the unsecured one of I really wanted too. I have no idea why this occured though?

dont know if this means anything now but here it is anyway:

When you get to the box to type in your security entry, be sure to use the dropdown menu to select what you want to type in, e.g, password or wep key. If you're trying to use a password and it is defaulting to WEP KEY that may be your whole problem.

Just saw your post, so ignore my last. Glad you resolved your problem. You're way ahead of me now.
