I have an interesting situation and perhaps you guys can give me a hand.
I'm installing Arch on a system that only has a WiFi; no big deal.
So, I get the live CD and
1. Start it and choose the network install (that's the only choice for this CD)
2. Go to tty2 and issue the following commands:
a. ifconfig wlan0 up
b. iwlist scan and I get:
wlan0 Scan completed :
Cell 01 - Address: 00:17:3F:93:05:63
Channel:1

Pairwise Ciphers (1) : CCMP

That's a good sign
3. Issue the command to link
iwconfig wlan0 mode managed essid ITTwo-wifi key "s:bbR\:\)cri2rr" retry 7
4. Test for association with iwconfig wlan0:
wlan0 IEEE 802.11bg ESSID:"ITTwo-wifi"
Mode:Managed Frequency:2.412 GHz Access Point: 00:17:3F:93:05:63
Bit Rate=1 Mb/s Tx-Power=20 dBm

Power Management:on
Link Quality=39/70 Signal level=-71 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:1 Invalid misc:0 Missed beacon:0
looks good so I do : dhcpcd wlan0
and it fails, over and over and over ...
Then after much testing I realized that if I issue the iwconfig wlan0 say 5 seconds apart on the first one it shows, as above, that is connected
and in the second one
wlan0 IEEE 802.11bg ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm
Retry limit:7 RTS thr:off Fragment thr:off
Encryption key:6262-525C-3A5C-2963-7269-3272-72
Power Management:on
It's not associated !!!
I have exhausted testing options to no avail?
Am I missing something obvious ... or not so obvious?
Any help/ideas will be appreciated.

The card is a Linksys and the chipset is recognized as : Linksys WUSB54GC v3 802.11g Adapter [Ralink RT2070L]

Do you have access to the router? If so, try changing the channel. It worked for me: one moment I'm having connection issues (on channel 12 - no other neighbouring networks above channel 7...) - the other moment all my worries are gone after changing the channel to 6.

looks like you're using wpa2 encryption. for me I had to use wpa_supplicant to connect to my network. i was a bit surprised by your post that you were able to connect (even just for a short time) just using wireless-tools.
so try it with wpa_supplicant:
wpa_passphrase ESSID "yourpassword" > /etc/wpa_supplicant.conf
wpa_supplicant -B -Dwext -iwlan0 -c/etc/wpa_supplicant.conf
good luck!

@ Treysis: you're right - I overlooked that one...

Thank you for the reply guys!!
@treysis, In the logs I got an error something like "<eissid> deauthenticated (reason 6)" or something to that effect and I was wondering what that means... I suppose you are correct and that the system is trying to tell me that I need to use wpa_supplicant. I hope that's part of the install CD
I'll give it a try and I'll report back .
Thanks for the help and ideas.

yes, it is on the install cd. Had to use it for my installations on two computers. Even ndiswrapper is on the cd, so it should be very easy to setup the network which is the most important part after all

Yup... It works.
wpa_supplicant was the solution.
Thank you guys!
