WPA connectivity in 9.04

[jward3010]

...hibernating has been giving me issues through all of this too!

Ubuntu is plagued with hibernation and suspend issues for reasons once again of not being able to get decent ACPI drivers from manufacturers. It has improved a lot right up to Karmic to the point that I use it a lot now, previously I was just used to shutting down.

Network Manager says that I am online with the WPA2 network!!
But I can not access anything online. What is happening here?

If you're still "technically" connected, try this:

ping -c 3 208.67.222.222

Then...

ping -c 3 resolver1.opendns.com

Then post the output of both if you can, it's a long shot but even a long shot is worth shooting. Hey, people win the lotto every now and then.

Hibernation only became a problem after I started working on the wireless; before that it was fine.


Although NM says I am connected, here is my output:
to "ping -c 3 208.67.222.222" I get
connect: Network is unreachable

and "ping -c 3 resolver1.opendns.com" gives me
ping: unknown host resolver1.opendns.com

OK, that was just going to test whether you had a DNS issue but it's definite non-connection issue. Basically if the first ping test had worked and the second hadn't, I would have concluded a DNS issue.

Can you give us the output of "nm-tool" and "ifconfig" once more, now that your connected?

I meant to ask for one other thing. I actually thought it would come up in nm-tool but it didn't.

route -n

I had a similar issue just last week. I was connected just fine, then all of the sudden my connection would drop. I scanned the wireless networks in the area and noticed a new wireless network. My neighbor decided to get herself a router. I went into my router's configuration and changed the channel from the default 6, to channel 1. I have been connected uninterrupted ever since.

Update...

- I took my laptop to an unsecured network, and it still said that it was connected to the WPA network (which was miles away). So I deleted the WPA2 network from NM and it connected fine.

- Back with the WPA2 network, no connection. But when I do

sudo renice +19 $(pidof wpa_supplicant)

during a connection attempt I am online. For about a minute. Then NM closes, connection goes off.

- If I reboot, NM says I am "connected" to the WPA2 network, but I am not. If I delete the WPA2 network from NM, reboot again, and reconnect to a hidden network and do

sudo renice +19 $(pidof wpa_supplicant)

I am online for a minute.... etc...

What does this mean?

[a-web]

But now I have been online for a number of minutes, and still going strong. Any thoughts on how to make this reliable? Or not having do

sudo renice +19 $(pidof wpa_supplicant)

every time?

[a-web]

I am marking this thread as "solved" because now I am able to get online to the WPA2 network reliably. Only issue is that it is neither easy nor fast. So maybe I will open a new thread for that issue. Thanks all for the assistance.
