---------------------------------------
Something is totally wrong with Upload, should be 3MB... and still request time outs on ping test to google....

Krystyna > firewall and antivirus are disabled
Krystyna > here is the screenshot of ping

i46.tinypic.com/jl3qe1.jpg Krystyna > ok
Eralynn > Krystyna, based on the health check, the upstream signal level is indeed low.
Eralynn > Are you using a wireless internet connection?
Krystyna > no i am not
Krystyna > this computer is connected directly to arris
Eralynn > Thank you.
Eralynn > Can you please do a reset to your Arris modem to boost the signals?
Eralynn > At the back of the modem, you will see a Reset hole
Eralynn > Using the tip of a pen or a paperclip, I need you to push the button inside the hole. Press and hold for about 5 seconds. You should see the lights on the device turn off and start flashing as it comes back online within 1-3 minutes.
Krystyna > did that like 30min ago, but ok do it again

stage.results.speedtest.comcast.···4602.png Eralynn > Fantastic!
Eralynn > It seems that you are already getting the expected speed of your package, Krystyna
Krystyna > ok great
Krystyna > but what about the request time outs on ping
Eralynn > I have run another health check on your device and the upstream signal level is already good
Krystyna > good to hear :smileyhappy:
Eralynn > Indeed.
Eralynn > Krystyna, since your internet speed is doing good, the packet loss and the time outs on ping test will not greatly affect your speed
Eralynn > Sometimes the ping test would also vary on the website that you are pinging
Krystyna > true
Krystyna > hopefully that will fix the issue
Eralynn > I am positive that it will fix the issue. I have also run a ping test on your modem and there is no packet loss from our end
Eralynn > There is indeed nothing wrong with your device and your internet connection, Krystyna.
Krystyna > well I do get high packet loss at night time, at day time is more stable, guess have to wait and see what will happen
Eralynn > Krystyna, if you get a high packet loss, you may follow these steps »
