TCP segment of a reassembled PDU length too small

Hello Everyone,

I am having a sporadic issue when I attempt to download files from a certain web site. One of the things I noticed is that when the download succeeds the TCP segment of a reassembled PDU packet length is 1514. When the download fails the TCP segment of a reassembled PDU is 1314. I am not quite sure what to make of this. I have been troubleshooting extensively and this is one of the differences that I have noticed. If anyone has any input or point me in the right direction I would really appreciate it.
