Question : Information needed to enable WEP Encryption in a wireless network

I am using a Linksys wireless hub BEWFS411 and have two computers (one running Win 98, the other XP Pro) with WUSB11 V. 2.5 adapters.  I'd like to enable the WEP Encryption.

1) At the hub, I need to choose between 64 bit and 128 bit.  What are the advantages and disadvantages of both?
2) Although it is clear how I would enable WEP at the hub, it is not clear what I need to do at the other two computers.  Please tell me what I need to do other than enable the WEP and enter a key on the hub configuration.

Answer : Information needed to enable WEP Encryption in a wireless network

IT depends, but usually there is a tab on your network card, or a small software (from the manufacturer) together with the card that enables you to configure all the settings of the card.
Did you check the manufacturer manual or instructions?
