we need way more info, what model wireless card?, what's the output of ifconfig,iwconfig, etc.

following is the output of ifconfig, iwconfig, and lsusb comands.
the wireless adapter is EDimax mode EW-7718Un. It is important to note that the computer is recognizing the available wireless networks, but fail to connect. It worked fine before upgrading to ubuntu 9.10.

try - reset your modem and wireless router, it works for me

amitk · 11-06-2009, 01:46 PM

I already tried the obvious...
It does not work

nimnull22 · 11-06-2009, 03:23 PM

First of all,
~$ ifconfig
wlan0 Link encap:Ethernet HWaddr 00:1f:1f:3c:16:69
inet6 addr: fe80::21f:1fff:fe3c:1669/64 Scope:Link
UP BROADCAST MULTICAST MTU:1500 Metric:1

Disable IPv6 - it is not good idea.
Second, report that Ubuntu incorrectly determines interfaces, iwconfig - doesn't have wlan
Third, check for the driver, could be wrong one.

rkski · 11-06-2009, 05:08 PM

It looks like the problem is due to the Ubuntu update. There could be a driver conflict due to the new kernel. What driver are you using? Also, how exactly do you try to connect and can you post any error message?
I am not too familiar with Ubuntu. Your best bet is to post directly to an Ubuntu forum because others upgrading to 9.10 with similar hardware will experience the same problem.
Good luck!
