I'm using network manager to connect. Also, tryed iwconfig. Results are same. I even try to connect to open access point — results are same. More information:

At this moment I try to connect to open wifi ap:

My distribution:

Drakmail@thinkpad-x220:~$ cat /etc/*version
AgiliaLinux release 8.0.0 (Sammy)

(Something between Slackware and Archlinux).

Also, I saw that wifi module to often trying to load a firmware file.

Any ideas what it would be?

I am running Fedora 16 on a Toshiba P750 with the same wireless card and a similar problem.

Some points from this thread seem plausible.

The driver integrated in the linux kernel is not enabling the wireless card to connect with wireless access points especially when there are:

  1. several access points with the same name (eg. in airports, universities)

  2. access points with blanks and strange characters in their ESSID

A solution that you could perhaps try (from this thread) is to boot with an alternative kernel. (In the thread they booted with 3.0.0-300 and this solved the issue.

Thanks for reply, Ariel! I observed, that with kernel 3.1.2 and 3.1.4 all works fine for me (but after this weird actions: update kernel (to 3.1.2 or to 3.1.4) with plugged ethernet cable, reboot, get DHCP address, try to connect to wifi ap, fail, do rmmod rtl8192ce, after it do modprobe rtl8192ce, wait 10 seconds, try to connect again, success, unplug ethernet cable). When I'll had some free time — I'll try to investigate it. –  Drakmail Dec 1 '11 at 20:11
    
I have these two kernels: 3.1.2-1.fc16.x86_64 & 3.1.0-7.fc16.x86_64. Both have problems with multiple-access-point wifi and do fairly okay on single-access point wifi (my home network). –  Ariel Dec 2 '11 at 16:02
