CANNOT CONNECT TO INTERNET open wireless router but can connect to WEP

I'm having a bit of a dilemma here with BT4. I can connect to my router that is secured with WEP using

Code:

---

sudo ifconfig <interface> down
sudo dhclient -r <interface>
sudo ifconfig <interface> up
sudo iwconfig <interface> essid "ESSID"
sudo iwconfig <interface> key KEY
sudo iwconfig <interface> mode Managed
sudo dhclient <interface>

---

but I cannot connect to my other router that is UNSECURED / OPEN (no password) Using code above as well minus key part.

I've tried using
# iwconfig wlan0 channel 12
# iwconfig wlan0 ap [MAC_OF_THE_ROUTER]

as well, and still no luck.

This is what I get

Code:

When I use WICD Manager as well, its stuck at "Obtaining IP address..." and it never connects.

Tried everything on google and BT forums (past and present)

Thanks in advanced

I too get this problem on a daily basis, I have recently been wondering if it could be because I am too close to the AP. My main problem is on my main AP - I cant connect despite having 45% signal. Are we the only ones this is happening to?

Have you tried connecting via Windoze? I can usually connect straight away with it, so I am assuming (But dont know) that is it a BT4/Linux thing?

Check the DHCP settings on your router.

Have you ran

Code:

---

networking start

---

Your iwconfigs can be run together

Code:

---

iwconfig interface mode managed essid "whatever" ap **:**:**:**:**:**  key qwerty1234

---

I've always run dhclient after iwconfig and putting the card back up.

Code:

---

ifconfig interface down
iwconfig interface mode, etc.
ifconfig interface up
dhclient options interface

---

Btw, Neither of your routers are secure.

On Windows I can connect to it right away with no problems so I'm not assuming a problem with the router.
