Hello,

Have you tried increasing the setBandwidthLimit() on the server side?
Sometimes it's default bw limits. Try:

client.setBandwidthLimit(500000/8,500000/8)

and see if that helps. (I'm assuming you have at least 1mb BW on your
FCS 1.5 2 r138--if not, try another setting that will max your
ceiling BW)

HTH,
Bill
