(FWIW, the channel and freq parts really should not be necessary.)

OK, voodoo time...

I suspect that "iwconfig wlan0" at this point will show a "0/100"
link quality and may show "Not associated" for Access Point.  True?

Link quality is "0/100" but it's Associated.

If so, please try these two steps:

        iwconfig wlan0 essid "BSNL"
        iwconfig wlan0

If link quality still shows 0/100, repeat a time or two (or three).
I find that I usually get an association on the second try, and a
non-zero signal level on the third.  Does this happen for you?

I repeated the above commands 2-3 times but no luck. I thought to specify my WEP key and with the WEP key also no luck. It get's associated with the AP but link quality is 0. LED also doesn't work. Note this time my network manager is running.

After disabling NM too I had no luck. I tried

modprobe -r iwl3945
modprobe iwl3945 disable_hw_scan=1

And then tried again but link quality is 0. During iwlist scan link quality is 71/100.

I don't have a good fault theory here yet.  I suspect it has something
to do with the MLME functionality in mac80211 (duh), and possibly the
interaction between that and the hardware-based scanning that the
iwl3945 uses.

Anyway, once you get a non-zero link quality then proceed to the
"dhclient wlan0" step.

Does that "work" now?  (I know it isn't pretty...)
