Try the Connectivity app in the control panel. That has an idle timeout tab. I cannot remember what the defaults are though. I set my idle timeout for WLAN as Unlimited but remember that the battery will be drained faster as WLAN is expensive on the battery.
Add to 5) minus is a design choice, you have got dot in the main keyboard area, but minus is not anywyhere on the main keyboard Add to the crashes and restarts... havnt had a single issue witht he device so far. What is your firmware version? Control Panel -> Device -> About product
A 128 bits WEP key is composed of a 24 bits initialisation vector and a 104 bits shared key. The latter is actually the key shared between the AP and the device. Since 104 bits = 13*8, it _must_ be 13 ASCII characters long, or 26 HEX digits. Even though your AP allows you to enter longer keys, it probably uses only the first 13 characters.
