First, i am sure the wep password is right.My wireless card's driver is right, because the Ubuntu supports it.And, the card can find the wireless router also.I have tried all kind of wep format, but none can the router accept.I search the answer in the web, somebody has the same problem in the Ubuntu 9.04, but their solutions are not fit mine.
The following is my card information.
Please Help me! Why can not I connect to my secured mireless router?

I tried the tool wcid also, but it could not fix it also.

My wirelesscard is: Intel Wireless WiFi Link 4965AG.
OS: Ubuntu 9.04 64Bit.

I havenot been able to get wicd to work automatically yet either. I did get WEP working though. First of all can you use a static IP address? This just takes one thing out of the equation. You can look at routing tables if it isn't waiting for a DHCP adresss. If you can't no big deal.
Either way, when your wireless card is connecting, execute the following in another window. sudo iwconfig wlan0 key XXXXXXXXXXXX The key should be in the format 1234567890abcdef if you are using the 40/128 bit key. Lower case. If that connects, then the issue is with the WEP key interface configuration.
