Constantly disconnecting from wireless network

Declan · 2010-06-27 23:32:27

Hey guys. I have a home network with WPA2 encryption. My laptop (has always been fine with wireless) connects, but usually disconnects shortly after. It's driving me nuts, having to click connect again and again. It's not that the network is disappearing, because it is still there in the available networks.

I use wicd. The signal strength is not very high (50%) but it generally stays well connected to other wireless networks of the same strength.

Can anyone help me? Thanks!

it could be that power saving is enabled which disable the wlan card if no data is transferred in a limited time, check those settings.

It seems to be off:

[declan@chilidog ~]$ iwconfig 
lo        no wireless extensions.

eth0      no wireless extensions.

it could be a dhcp issue, check /var/log/everything.log for errors, and once you get disconnected, use ifconfig to see if you still have an ip address attached to the wlan0 interface and if its still associated with the AP.

What wireless card do you have? (I have found that using wpa_supplicant directly — either with autowifi... or now with netcfg (which is then indirectly) — gives a more stable connection than wicd does. That's why I stopped using wicd...)

Get a wireless scanner and look how crowded the channel is. It sounds more like an interfence issue than anything else.

I will try this.

Broadcom 4311. I am indeed using wicd, but it has been very nice for me in the past.

It's channel 11, which is typically the most crowded, along with 6.

Run

iwlist [interface] scan

and see how crowded the channels are.
