Widi Keeps Disconnecting

Hi, I am having problems with my Widi continually disconnecting.  Intitial connection is made without incident, but I get disconnects within 30 minutes or so and they intermittently continue until I finish with the Widi.  I'm watching videos in the form of FLV, AVI, or MP4 files saved onto my hardrive, and I'm using Windows Media Player (12.0.7601.17514) to view them. I am sitting in the same room, approximately 5ft from the Widi adapter (Belkin Screencast), with nothing physically blocking the signal.

 

Here is my setup:

Lenovo T420 (2410M integrated video; 8GB RAM; Win7 Home Premium 64-bit)

Intel Wifi Link 1000 BGN

Belkin Screencast: Hardware 2.0; Firmware 3.0.9.0

 

I think I have the latest drivers.

 

Software/drivers:

Intel Widi: 3.0.13.0

Intel Proset Drivers (Intel Wifi Link 1000 BGN): 14.3.0.6

Intel My Wifi: 14.3.0.0

 

I believe the problem is either on the laptop side of things or the noisy environment.  The same room includes another wifi router/AP: Huawei EchoLife HG520b (I think it only operates at 2.4GHz). Also a cordless phone: BT Graphite1500 DECT Cordless Phone w/Answering Machine (also only-2.4GHz I believe).

 

Could you help me isolate this problem?  I haven't been able to figure out how to force my Belkin Screencast to use 5GHz-only to eliminate any noise issues. I also have updated all software on my laptop and Widi adapter (firmware) so I'm not sure where to go next.

 

Thanks,
jforce

    JForce,

     

    Thanks for the post and sorry to hear you are having difficulty.

     

    I reviewed all the information in your post and tried to see if I could find anything similar out there.

     

    Here is a link to Belkin about a very similar issue to what you are seeing: http://en-us-support.belkin.com/app/answers/detail/a_id/6717/~/the-audio-while-using-my-screencast-av-4-is-garbled-and%2For-has-static

     

    Basically there seems to be an ongoing issue with this unit and noisy environments. I did not find anything that would tell me how to force that device to the 5gHz range either.

     

    The suggestions that they made in the post I included above was to try and eliminate some of the noise in the area and reposition the unit to see if that increase communication. I will say however, that based on what you have going on in the same room with all of those devices that you will probably want to physically move some of that equipment. It sounds like you have a lot going on in that room and from what I see from Belkin, that unit does not like lots of noise.

     

    If you have more information that you would like to share or have more questions please feel free to post them here.

     

    Thanks,

    Thanks Paul.  I'm inclined to think you are right and that the environmental noise is the primary issue. However, it might be worth mentioning a few things.

     

    I noticed that the link you posted is to another Belkin product with a similar name.  The Belkin Screencast AV4.  My widi receiver is actually the Belkin Screencast [F7D4501, so only 1 AV, not 4]: http://en-us-support.belkin.com/app/product/detail/p/6125  It could be that the tx/rx hardware is identical otherwise and that the same issues would be present in both devices.  I just thought it might be helpful to note the difference if it meant you migth have any further ideas.

     

    Secondly, I also noticed the issue mentioned in the link you provided refers to "audio that is garbled and has static."  My problem is not really a dirty audio (or video) signal, rather it is that intermittently the entire connection is lost.  While this could be a related issue, it does seem to be a different manifestation.  Perhaps this also might help track down more precisely what the problem is being cause by.


    Thanks again for your response and hopefully this helps give some more specifics to diagnosis these difficulties.

    You will not be able to get the Belkin adapter to use the 5GHz band because your laptop 1000bgn WiFi NIC only supports 2.4GHz. You will need to use the Intel 6xxx series WiFi NIC for 5GHz support.  In order for WiDi to use the 5GHz band, both your laptop and home AP need to support 5GHz and you need to connect your laptop to the Home AP 5GHz band.
