bd6 is not a model number so could not look at user manual to confirm this is needed - more an assumption based on technical logic

Open your dial pad and dial ##847446# a menu will come up select edit and a box will open, enter 10 zeros in MDN and 10 zeros in MSID then select "ok" the phone will restart then try activating again.

which windows are you using?
Turn on your wifi and then
For windows 7,
go to the bottom right corner and press the internet connection icon and then select your wifi connection.

For windows xp,
go to network connections and then to connect to a wireless connection

that should do.

This can be so many things that trying to fix it by just reading the post, and without knowing if there was any changes, it's pretty difficult.
If the problem is that while searching for the network, the wifi don't see it, this could be the drivers or the wifi card.
If the information to connect tot he router is lost overtime, this could be a faulty memory RAM or the back up battery going bad.
Then again, the diagnose could be anything.

From the manual, here's what it says about cleaning:

And in order for the TV to recognize your wifi, you'll need to plug in a wireless network adaptor to one of the USB ports. (network adaptor sold separately.) Follow these instructions to establish a wifi connection, and then follow the on-screen instructions for wifi/network settings.

Best of luck!

make sure your not connected to a wifi connection with a password, or in the interm, just use the internet off 3g if you have it, or edge networks.

A wifi connection reverting to available could mean a wrong password enter or a wrong encryption type.
If the available wifi networks are being use as hotspot, then you probably needs to register in order to use the wifi network.
If it's a private network, check if the network is at band 5 or 2.4. Just some tips for you to check out.
