My wireless signal always used to be full...no it fluctuates between 1 and 3 bars. Nothing has changed and I can't figure out what is going on. I have spent the past 3 hours messing with my router setting and nothing makes a difference. Netflix used to stream in HD perfectly. Now it takes forever to load and is contently downgrading quality.

I took my laptop downstairs and it gets 4 our of 5 bars (with a wireless n adapter).

I am debating buying the wireless n adapter for the xbox to see if this solves the problem.

What do you guys think? Will the wireless n adapter solve my poor signal problem? Also, any idea why I would have full signal for months and then all the sudden poor signal?
