I use a Lenovo A1. It connected great to the old router with WEP encryption but I just got a new router from Verizon FiOS. I set it up with WPA2 because my house is in range of several neighbors and I may have had a "wardriver" on my street once. I also entered a preset key. I have tried to connect my A1 with no luck. It sees the router, good signal strength, but shows the padlock on the signal icon. I would like to be able to connect using the preset key, but don't see any option, or need to know if there's an alternative method I'm not aware of. The Verizon rep tried for about 45 minutes, then confessed that they don't have a lot of Android info. In case it's relevant, the router is an Actiontec MI424-WR Rev E.
