Scenario: I am having trouble syncing my ERB9250 to my wireless
router.

When asked to input the wireless security settings after choosing the
correct wireless network, manually choose to set the key, because it is
set to 128-bit by default.Then manually select the key type, because it is
set to ASCII by default.

In the above case, the wireless network has a 64-bit hexadecimal key so
manually set the key length to 64-bit and the key type to hexadecimal
digits.
