Step 2: The default username is Admin and the password is blank (nothing). Click Login.

Step 3: Click on the Setup tab at the top and then click on Wireless Settings on the left side. Then select Manual Wireless Connection Setup.

Step 4: In the Wireless Security Mode dropdown list, select WEP encryption. WEP is a deprecated wireless encryption standard and we strongly advise against using WEP. It should be used only if you have a very old device, since it offers weak protection and will slow your network greatly.

For 64 bit keys you must enter 10 hex digits into each key box. For 128 bit keys you must enter 26 hex digits into each key box. A hex digit is either a number from 0 to 9 or a letter from A to F.

You may also enter non-hex digits into a WEP key box. Input 5 characters for 64 bit keys, or  13 characters for 128 bit keys.

Step 5: Click on Save Settings to save your settings.
