You will notice (from apport data) that the kernel I am using is not the
stock kernel, but this problem existed in exactly the same way when I
was using the stock Xubuntu 11.10 64-bit kernel.
** Tags added: apport-collected oneiric
** Description changed:
I am running Xubuntu 64-bit on a Lenovo ThinkPad X220, and my WiFi is
very slow and disconnects randomly on some WiFi networks. It also
refuses to even connect to some networks. All of these are networks
which have excellent signal strength and which many other people are
successfully connected to. All of the networks I have problems with are
unencrypted/public, but that may be pure chance. My home network
(encrypted with WPA2, Netgear router) is 100% flawless. 50% or more of
public WiFis I use experience this issue. The issue does not appear on
other machines on the same connections. I believe there may be an issue
with he iwlwifi driver that causes this. My wifi card and driver details
are as follows:
03:00.0 Network controller [0280]: Intel Corporation Centrino Wireless-N 1000
[8086:0084]
Subsystem: Intel Corporation Centrino Wireless-N 1000 BGN [8086:1315]
