Xfinity throttling this year

I recently got a new modem to replace a much outdated one that had been working well up untill december. I assumed my speed drops and inconsistency was due to the outdated modem so after receiving a new modem I got my download and uploads back up to normal high speeds and after a week it started to drop back down to the point where the wifi was unusable and a directly connected desktop was getting 6mbps down (basically useless). I ran speed tests frequently for a week and these drops stayed consistent. Overall the xfinity speed test site was giving me way different results than any other reference. I've read else where on the forumns saying this is a "coding" issue in my modem.. either way I'd like a solution to these speeds

If you want to troubleshoot this yourself, please see Connection Troubleshooting Tips. If you still need help, please provide Information Requested for Connection-Related Posts.

If you are using Wifi it's best to switch to an Ethernet cable connection if possible while measuring speed and checking the reliability of your connection to Comcast.

If you can't find the problem or you'd rather have Comcast do the troubleshooting, call them at the phone number on your bill or 1-800-Comcast, or chat with them using the Internet Support option at https://support.xfinity.com/chat. If they can't fix the problem remotely, insist they send a tech out to identify the cause and correct it.

If the tech finds bad coax, splitters, amplifiers, or connections in your home (even if Comcast originally supplied them) you'll probably have to pay for the visit unless you have or sign up for their Service Protection Plan (https://www.xfinity.com/support/articles/service-protection-plan, about $6/mo) and keep it for at least 60 days. If the trouble is due to a faulty Comcast modem, eMTA, gateway device, or anything outside your home, you shouldn't be charged.
