Here is a test we can run to find out if the local network or ISP is having issues :

  1. Go to https://iperf.fr/
  2. Click on ''Download iPerf Binaries''.
  3. Download the most recent version of the file for your Windows version (it will load a zip file on your computer)
  4. In your computer, navigate to the Local disk and extract the zipped file.
  5. Open this folder.
  6. In the naviagation bar, erase the actual path and put "cmd" (this should open your cmd prompt at the right place).
  7. In the command prompt window, please run the following commands (only one at the time so we also receive the result):
  8. Save the results you got in a word document please and reply to this email with the document attached.

Here are both commands:

iperf3 -c 199.244.77.86 -p 20002 -u -b 1M -t 30 -P 4 -R

iperf3 -c 199.244.77.86 -p 20002 -u -b 1M -t 30 -P 4

Please provide the results of this to Support so we can evaluate further.
