I had FIOS installed a week ago and the tech showed me a speed test that confirmed my 20/5 service. This week-end, I ran the Verizon speed test and it only showed 9.6/4.2..... I ran it several times during a 2 hour period with very similar results. Not the 20/5 I am supposed to get. What can I do to find out what has hapened ?
One thing is if you are running Vista make sure you have service pack 1. If fixes some network speed issues. I had run into some similar issues and rebooting my router helped. Based on firewall logs I think it may be a type of denial of service attack which slows down the connection. One day I had a flood comming from Asia Pacific Net, and when I rebooted the router it stopped and the connection took off. The firewall log on what I am running shows a flurry of attacks even when I have ICMP responses turned off and the router runs in stealth mode. Just one idea. I have seen my connection do that at times, but for the most part it is more fast then slow. I too have 20/5. If it does not come back up to 20 I would call tech support and have them check things.
I ran from whatever site the default Verizon speed test was configured to. I will look tonight to see if it has choices.
