Is anyone else having this issue?

We have the SatBox S8200, which has the feature of connecting to the Internet via Wired or Wireless. I have set ours up to the WiFi router in the Network Setup and checked that it is connected and active. Also when the SatBox boots up when it is turned on a check box in the bottom right hand corner of the TV says WiFi Active this confirms that WiFi is Active to me ...

However, over the last few days when we turn the TV and Box on a info box appears saying "Network updates available" and that the Box will update in automatically after a 20 second countdown, then the Box goes to update and this is when a check box appears in the bottom right hand corner saying WiFi Inactive !!!!!!!!!!!!!!!!!

Then the unit reboots and goes back to live TV ...

I don't get what's up ???

Could it be that the WiFi signal strength is too weak - on the Network Setup info screen it tells me it is at 54% could this be strong enough ...

Or might it be a software issue with the Box itself ...

any suggestions ????
