Problems with wireless connection on squeeze


hi

Since the upgrade from Lenny to Squeeze on my Notebook Toshiba Satellite Pro U200 with Intel Pro/Wireless 3945 ABG I have wireless connection problems.
The connection breaks time to time and sometimes cannot connect automaticaly after restart.

My /etc/network/interfaces:
Code:
# Wireless
allow-hotplug wlan0
auto wlan0
iface wlan0 inet dhcp
   wpa-driver wext    
   wpa-ssid myessid  
   wpa-scan-ssid 1
   wpa-ap-scan 2
   wpa-proto RSN 
   wpa-pairwise CCMP 
   wpa-group CCMP 
   wpa-key-mgmt WPA-PSK
   wpa-psk mykey
Under Lenny I didn't have these problems.

BTW I didn't change anything on the wireless or network configurations on the notebook and on the wiereless router.

Network manager has given me wireless issues in the past. The best solution I've found was to remove network-manager and network-manager-kde (since I use KDE), and installed wicd. It's performance is as it's name suggests.
Which one are you using?.
Is the firmware-iwlwifi package installed or are you using firmware files you manually installed in the past?

I'm using Gnome.
I've removed network-manager, installed wicd and now it seems to work.

Just to wrap this topic up: the original problem was the 'auto wlan0' line in /etc/network/interfaces, which removed it from network-manager control. There used to be problems with network-manager (especially with regard to WPA security), but the version currently in testing (Squeeze) should work fine. Wicd is a fine replacement, though.

P.S. Most of the wpa-... entries for the wlan0 interface in the OP are superfluous, since they're defaults.

I could do that, but I'll leave this for you as an exercise to discover. It could involve a bit of experimentation (commenting various lines and trying to make a connection); or it could involve studying man-pages for wpasupplicant, interfaces, ...

Have fun!

I've got a Lenovo R61i with Intel Pro/Wireless 3945 ABG. I installed Squeeze from scratch and I followed this steps:

1) I installed firmware-iwlwifi package from the repositories
2) I removed the KDE Network-Manager and I installed wicd
3) I modified my file /etc/network/interfaces adding this rows

# Wireless
allow-hotplug wlan0
auto wlan0
iface wlan0 inet dhcp
wpa-ssid myssid
wpa-key-mgmt WPA-PSK
wpa-psk mykey
4) Now it works perfectly. BTW I use a wireless router Lynksys WRT160n WPA-TKIP encryption

If you use nm/wicd you can leave only the "lo" interface in your /etc/network/interfaces and let the apps handle your connections.

Smile Wireless connection on Squeeze

You're perfectly right.
My problem is that I started working with computers in 1981, with an Univac 1100 and at that time the graphical interfaces were maybe only in the dreams of Steve Jobs.
So I prefer fighting with a conf file insted using a GUI

Thanks for you post
