[SOLVED] Comcast Internet Help

[John2090073]

I am hoping that someone here can help me as Comcast can’t seem to. I have Comcast internet and I was originally paying for 400mbps download and 10mbps upload and was getting speeds in the ballpark of 400-500mbps. I upgraded recently to their 1200mbps download and 35mbps upload for streaming purposes and the price I got it at. Issue is every since they upgraded me I’ve been getting speeds of 300-500mbps downloads but I’m getting 30-40mbps upload. They sent a tech to my house and the tech said all the cable on the outside of the house was golden and that I had a bad modem. He went to the truck and gave me a new modem and said give it 24 hours and you should be seeing your speeds. It’s been 48 hours and I’m still only getting 300-500mbps download. All these speeds I’ve tested have been through an Ethernet cable to my PC. However, when I do these speed tests on my phone I am getting 600-700mbps download speeds on Wi-Fi which makes no sense to me. So my question is has any dealt with this issue? Do I need to run a new Ethernet cable to handle the speeds? MB says it handles speeds 1000mbps. PC is only about 4 years old. Do I need to purchase my own modem? I am lost. I hate paying for something that I’m not getting.

They keep trying to tell me that my speeds will change depending on who’s online in the area but when I had the slower speed I never had anything until 400mbps and now there are times I’m not even hitting that with 1200mbps plan. Makes no sense to me.

I am using speed test sites like these:

According to the website for your motherboard:

LAN

• 1 x Killer™ E2500 Gigabit LAN controller

Notoriously problematic Killer LAN controllers. Try disabling any killer software on the computer. But before you do that, make sure you set your bandwidth limits on Killer Control Center very high: https://www.dell.com/support/kbdoc/...internet-speed-using-killer-ethernet-adapters

If that doesn't work, after uninstalling the killer software. Try running TCP Optimizer and set everything to windows defaults: https://www.speedguide.net/downloads.php

I had to uninstall Killer Control and bam was getting speeds of 800 to a little past 900. Something so small to fix an issue. Thanks!

During the time that killer was selling ethernet solution it was fairly well known that the whole concept their company was built on was all smoke and mirror. You can't actually affect the network traffic outside your machine and if you have a network bottleneck inside the machine you have a very strange issue.
It used to be the first thing I would check when looking at new motherboards. If it had a killer chipset it was a automatic disqualification.

I had hoped this silliness would completely disappear when intel purchased killer. Now intel puts out software than tries similar garbage. Not quite as bad since they are not putting the software into the drivers themselves like killer did so it is easier to delete or not install.
