It seems with my router, the WZR-HP-AG300H?, it does not drop connections as far as laptops, wired, etc. However, it seems that I am having huge issues with my iPhone and iPods. It seems that for them to detect the home sharing that iTunes offers, a lot of the time I have to go to wireless settings, and then I have to hit apply and then save, even though I do not change anything. That then logs everyone out from the router, but magically home sharing shows back up. It does dissapear again though, timeframe is variable.
So, what is going on? Everything seems to work fine except for this.
