Latest questions about "sony ericsson wireless manager"

I have Sony Ericsson Wireless Manager 5 and in the first few days it worked well, but now its speed is with 80% slower. Does somebody steal my Internet or just my Internet connection is slow?

I use Wireless Manager 5 v.2 on my LG Netbook. Recently I have reset the information fields to zero and sent a small email file of about 100 KB for the test purpose.
