I have set WEP password for my house wifi also. U can save the connection settings in your Tube. Follow this:

1. Connectivity
2. Destinations
3. Access point - Add new access point

Then you'll have the options of automatically checking for available access points. If your wifi SSID is not hidden, then just say Yes, your phone will scan all available network.

You can then play around with the settings, WEP or WPA key, etc.. Then save it.

Next time u connect, no need to select hidden network and re-enter the WEP/WAP key..

Cheers
