WEP is not supported? Broadcom 1505 wireless card, RHEL5

I installed ndiswrapper. The card is able to search for APs that are in range.

Code:

iwlist wlan0 scan

There is a wireless AP called WirelessAP5-G. Its encryption setting is WEP128, and password is 26 2's (hex).

Code:

cat ifcfg-wlan0
TYPE=Wireless
DEVICE=wlan0
BOOTPROTO=dhcp
ESSID=WirelessAP5-G
MODE=Managed

cat key-wlan0
KEY=222......222 (26 2's)

ifdown wlan0
ifup wlan0
Determine IP information for wlan0... failed; no link present. Check cable?

I also tried to change the content of key-wlan0 to "KEY=0x222...2" (all 2's are hex), but this time an error pops up saying "invalid configuration".

The output of "iwlist wlan0 key" also confuses me:

Code:

Authentication capabilities:
  WPA
  WPA2
  CIPHER TKIP
  CIPHER CCMP

WEP is not listed here.

It is strange that the wireless device successfully obtains an IP address after abandoning the GUI network program but modifying /etc/sysconfig/network-scripts/ifcfg-wlan0 and key-wlan0 files directly (ifdown wlan0; ifup wlan0).

I found that sometimes even thouth configuration is changed via system-config-network, the ifcfg-wlan0 and key-wlan0 are not at the same time, or the changes made to these two files are not what you want exactly.
