Hi vancanfan67 -
That's unusual! Does this issue occur when you're connecting at home, or remotely, or both? One thing you can try is to test your speed with both machines on the same network by connecting to speedtest.net (or similar site). If the test is returning IDENTICAL download and upload results, then you can at least rule out any issues between the two machines...
Let us know how that goes - there may be additional steps you can take based on those results.
