[Bug 1164567] Re: Wireless screen doesn't connect to selected wireless network

[Mathieu Trudel-Lapierre]

Are you sure the network is open? Seems to me like it's failing to auth due to cached auth data:
#define WLAN_REASON_PREV_AUTH_NOT_VALID 2

That said, it seems like there are further issues with connecting;
direct probes fail which may indicate bad signal.

Additionally, you may want to try disabling 11n; which may help:

sudo rmmod iwlwifi
sudo modprobe iwlwifi 11n_disable=1

Or try to change regulatory domain:

sudo iw reg set US

And try to connect again, see if either changes improves the situation.

Thanks!

Title:
  Wireless screen doesn't connect to selected wireless network

Status in “network-manager” package in Ubuntu:
  Incomplete
Status in “ubiquity” package in Ubuntu:
  New

Bug description:
  This is with the Ubuntu GNOME Beta 2 candidate image.

  1. Select Try Ubuntu GNOME
  2. Don't connect to wifi.
  3. Find Install Ubuntu-GNOME in the Activities Overview and start the installation.
  4. When you get to the Wireless screen, select a wifi network (In my case, the wifi network is an open network but captive portal)
  5. Click Connect.
  6. ...Nothing happens

  Workaround:
  Click the network menu in the top right corner and connect to the wifi point instead.
