Does it sound like these issues require technical support/repairs, or just a different approach?

Problem 1: Wii
My Wii no longer connects to Wifi very well. It finds the initial connection, but once it comes to searching for another player, it cuts out if it doesn’t find a player before a minutes time. If it does, it isn’t guaranteed to last.

Reasons why I think it is hardware:
I never once touched anything on my router. It worked fine for over 6 months and stopped working. Nothing provoked the cut out of Wifi, and I even attempted to do everything the internet told me to do. Not only that, but it takes FOREVER to connect to a DS, which doesn’t even need Wifi to find. And the DS and Wii both use the same components to connect to Wifi, and the DS hooks up just fine.

Problem 2: iPhone
The battery sucks now. Its not a 3G or anything. Pretty much after an hour of use on the bus the battery went from100% to about 40%. Shouldn’t I be getting more than an hour and a half of use here? Should I contact Apple or is there something I can do? By the way, the new update that is supposed to work on the battery life did nothing for me.
