    DCT from 3.3.1 to 3.5.2, OR tcp patch for 3.3.1?

    MiDe_2164101

      I am serving larger pages on a soft AP in Wiced 3.3.1.  It works well at short range, but as soon as there is some distance of packet loss, the pages essentially 'freeze' and don't load.  I believe the main issue is either the DUP ACK as described here (https://community.broadcom.com/thread/5141), or "Fixed TCP restransmission for NetX_Duo" as described in the changelog to 3.5.2.

       

      I tried Wiced 3.5.2 and the issue seems to be fixed or improved.  HOWEVER, now i'm stuck with the incompatible DCT issue.  There's doesn't seem to be any way for me to update my existing devices in the field without directly reprogramming them.

       

      That problem is described here: https://community.broadcom.com/message/22724#22724

       

      So, my question is, what's my best route of attack?  Should I attempt to port the 3.3.1 DCT code forward into a custome 3.5.2c, or am I attempting to back-port the TCP retransmission netx_duo into 3.3.1?

       

      Or is there a patch available somewhere for 3.3.1?
