I think I have a defective Wii (please help)

My Wii has this problem where it'll keep on not syncing up with the controllers (already synced). It'll basically after entering or leaving a channel (any random channel) the controllers won't sync up any more as if I had never synced them. Then when I try to re-sync it won't detect the remotes. This is happening more and more frequently. And I also noticed that the internet is going a lot slower than usual but on the computer and router it's fine. Please tell me if I should keep it longer (it's been happening since about January) or if I should send it back (I still have a warranty left).

Do you have  any other bluetooth devices in the area that might be interfereing?

You should definitely at least call Nintendo about it. They'll take care of you.

I too had to unplug my Wii once or twice for that problem
