Who's fault is my latency

60mbps down and 5mbps up is a good speed for Xbox Live.

You can always tweak your Router configuration to achieve the max speeds possible.

Like as changing the DNS to Public DNS, changing 20/40 coexistance to off ("good neighbor policy"), making sure the speeds are set to max for the wif, making sure you have WPA2 security protocols, set priorities for your Xbox/PC so they receive the majority
speed when connected, checking your conected devices to make sure no one is piggy backing off your connection.

ISP's claim that during the afternoon into the night, is the most actiive times of the day, as everyone is getting home or off work and searching and using their devices. Wether this will change your speeds is up to how much flow your ISP can handle at once.
Their servers may become overwhelmed with responses, creating a bottleneck, in which you see up and down on your latency.

latency is how long it takes for the ISP device to accept information, process then to distribute such information..... IE console asks router a question then router replies with an answer. Latency is measured in milliseconds and is the measurement of how
long it takes the router to respond. I would be contacting my ISP

Heph,

Thanks for the reply. I definitely did all those provided techniques, the xbox has always been hardwired, but nothing worked. This is what led me to believe it was Comcast and what Fragg was saying. Happy news though by some Christmas miracle I have had
my 50 download and 10 upload (what I am paying for) and 0% packet loss. I believe it was my constant harassment that got me a higher tier support tech and maybe got the problem fixed.

I have received no reply from Comcast or verification so I am not sure if I am out of the woods yet, but hopefully these two days are what I will have for a long time. Thanks again I will keep you posted.

Hey there Doerbird. I had a great Christmas, and I hope you did as well. The symptoms you're describing could be caused by a few different things. Let's go through a few of them and see what sticks. There are some known issues with the EA4500. First off,
there is a channel width setting in the router that can affect the Xbox One, and not have any impact on your other devices. Go here to troubleshoot that (

forums.xbox.com/.../1513583.aspx ). Also, there could be a problem where there is too much wireless traffic on the same channel your router is using. Here is how you change your wireless channel: (

forums.xbox.com/.../366205.aspx ). Finally, I would like you to go down the troubleshooting flow that should address the symptoms you're seeing. (

support.xbox.com/.../slow-performance-solution ). Once you are done with all of this, please let me know the status. Thank you, and good luck.

If your speed is fluctuating by determining from the speed tests, then it's your ISP. If it was your router and/or your modem, it would be happening all of the time.

It could be they have over sold your node (A "Node" is an area around your neighborhood which people share the bandwidth). If your Node is over sold, then during peak times (Towards late afternoon and early evening) your speed will decrease, and your packet
loss will suffer as well.

Will Comcast agree that this has been done? No. ALL ISP's over-sell their system. They aren't planning on everyone being online at the same time.

I would call Comcast and talk to a higher-tier tech support and ask how many people are on your node and such.
