Possible DDoS attack, not sure

  1. Im having a few connectivity issues. I am unsure if it is malicious in nature. A few people told me that in their opinion it was possibly a DoS or DDoS attack. I called my ISP and was told, that from their end, signal from my modem was strong, but the packet loss was huge.

    I am able to connect to the internet now, however it is VERY slow. This all started about 30 hours ago, yesterday while browsing the web, I started to experience slower and slower speeds, until I was unable to connect to the internet at all, and it finally allowed me to connect again around midnight last night, with these very minimal speeds.

    Here is the results of a few tests I ran recently.

    speedtest.net
    This is a test from today.

    This is a speedtest ran about a week ago.

    Ping statistics for above hosts:
    Packets: Sent = 15, Received = 8, Lost = 7 (47% loss)
    Approximate round trip times (RTT) in milli-seconds:
    Minimum = 162ms, Maximum = 442ms, Average = 166ms


    I preformed a quick scan with malwarebytes that came out clean, I also ran tdsskiller with clean results.

    Is there anymore more tests I should run?

    Thankyou for taking the time to read my post.

    When this starts to happen, what happens if you disconnect all of the other pc's on the network except yours? Then try connecting the others back 1 by 1 and see if the packet loss jumps back up.

    Check the link-speed of your network connection from "Network Places", try forcing 10/100 and also try forcing 10/100/1000 (1Gb/s) do a speed test with each. If no avail revert the settings to your prior configuration (automatic by default) and reset both your router and modem (unplug and remove batteries for about 30-seconds) now re-try.

    Have you had any luck? I think I am getting DDoSed. I think they gained access through my Skype VoIP calls - but I'm not sure. I read some articles about professional video game streamers that had a similar problem.
