I have a strange problem about sending and receiving data on
the smdk2410 demo board using WIN CE .Net 4.2.

When I use pocket IE on the demo board to download something
from a web server on a typical desktop PC, there's no problem at all.

But if I use the pocket IE to download some 'large' file ( > 10 KiloBytes)
from a web server on another smdk2410 board, packets are lost and
the pocket IE hangs. So I stop the IE and download files from the desktop
PC again and there is no problem again.

I have written a small program using the MFC CSocket to transfer files
between 2 demo boards and the same problem happens.

The conclusion is : there is no problem when a desktop PC communicates
with the board but when 2 demo boards commuicate, large amount of data
transfer cannot be carried out.

I am quite sure it is a software problem as I have tried to use a Linux
image
on one board and download something from the WIN CE board and there
is no problem, too. So I suspect there is something wrong with WINCE.

I have downloaded all the QFE to update the platform builder already but
the problem still exists. What can I do ?
