I have Ubuntu Server 13.10 and I used it earlier to connect to many access points

I used ifconfig, iwconfig and /etc/network/interfaces file to do that

Now, the WiFi adapter is de-associating from the access point of my interest, there are others in range

I was wondering where is the Network Manager or if the old settings for other APs are still stored and the adapter is trying to associate with them based on the highest RSSI

If they are still stored somewhere, how to delete them

Thanks

Update 1:

I installed the network-manager package

Now, I have this directory /etc/NetworkManager

Is it possible to use it to find the stored wifi settings?

Update 2:

This is what I use in the interfaces file

auto wlan0

iface wlan0 inet manual

wireless-essid ASUS-2.4

wireless-key 1111111111

wireless-mode Managed

Your /etc/network/interfaces file uses the method 'manual' (I think you mean static) but declares no static address and other details. It also implies that your network is encrypted with WEP. WEP is extremely insecure and can usually be cracked in minutes. I strongly recommend you change the encryption in the router to WPA2-AES and then set up /etc/network/interfaces like this:

auto lo
iface lo inet loopback

auto wlan0
iface wlan0 inet static
address 192.168.1.150
netmask 255.255.255.0
gateway 192.168.1.1
dns-nameservers 192.168.1.1 8.8.8.8
wpa-essid ASUS-2.4
wpa-psk 222222222222

Of course, substitute your details here. Restart the interface:

sudo ifdown wlan0 && sudo ifup -v wlan0

Now is it stable?
