I am running 10.04 with the latest updates on an MSI 1719 (GX700) laptop and am unable to get it to connect to my wireless network.

It sees the available networks and allows me to go through the setup process but always fails to connect after I input the pass key.

As per a response I found here, I am posting the following information:

I have verified that the package "wpasupplicant" is installed.

And I initially thought that it must be a problem with my router so I did a hard reset on it and set it up from scratch with basically just the defaults so I seriously doubt that's the problem.

FWIW, I'd expect the router to privide DNS servers for /etc/resolve.conf so unless you're connected I'd expect that to be blank. –  Amanda May 26 '11 at 18:47

Since ifconfig shows wlan0, I think that the driver is installed and working, so there is probably some other problem...

So, just an initial stab at eliminating the most common problems:

  1. Have you installed the package "wpasupplicant"? This package provides functionality for encrypted network connections (WPA)

  2. Have you manage to successfully connect to the network before? If the router you're trying to connect to has a MAC-filter (i.e. the router is setup to only allow connections from a configured list of computers/network cards), you may need to properly configure the router...

  3. If none of the above works, you may try installing the package 'linux-backports-modules-wireless-lucid-generic'

/N

Would you look at the posted feedback? I have the wpasupplicant module installed. –  Noah Goodrich Sep 17 '10 at 14:41

Have you tried setting up the router with not encryption, just to see if that is the problem. You problem could be related to: bugs.launchpad.net/ubuntu/lucid/+source/… –  Nicke Sep 18 '10 at 7:56

you should be able to find more info in the syslog. For example, when I connect to a network, it shows this:

Sep 17 15:13:11 excelsior NetworkManager: Activation (wlan0) successful, device activated. Sep 17 15:13:11 excelsior NetworkManager: Activation (wlan0) Stage 5 of 5 (IP Configure Commit) complete.

after some other messages about DHCP and address info.

Try downloading the latest drivers from Ralink.com. I have an MSI with a similar card and had to build the drivers from source. It's very easy to do, and it now works perfectly.

I've experienced difficulties with Realtek wifi-card on Ubuntu 9.10/10.04. Following this guide at least made the wifi-card usable. Limited support in 9.10/10.04 for my Realtek card is a known issue. I often, but not always, lost connection, when my session timed out.

Workaround (9.10/10.04): I simply turned off the wireless access and turned it on again using NetworkManager applet. Not elegant, but it worked.

Solution: Upgrading to 10.10 (beta) has provided flawless support so far.

Ok, ruling out the simple things...

Have you actually checked that the transciever (router) is not of the older wireless systems? (Wireless A, B, etc etc).

I'm unaware of your network situation, or your level of knowledge; but a similar sounding problem I know of was resolved due to the older router being unable to make sense of wireless N devices.

Also, early wireless devices are unable to connect to multiple machines.

Again, apologies if that was a patronizing answer, but it can't hurt to help! :)

Install this kernel please:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.33.3-lucid/

RT2860 driver in Ubuntu 10.04 has issues that prevent it working. Just installing this kernel should provide you with a working system.
