Consistently slow speeds

I've been experiencing significantly slow speeds even after multiple restarts of the modem. I have a wired connection to the modem on my PC and am barely getting above 100 down. Wireless devices are barely over 40. I'm paying for 1GB speeds and can barely get a Netflix show to load without buffering in the next room. This is extremely frustrating when the app and customer phone line just say "nothing's wrong, goodbye" and there's no way to talk to an actual human.

You’re going to need to provide a few more details to get some useful assistance in here. Which modem you’re using would be a good place to start.

I'm using the Arris modem.  It isn't a modem problem.  I get the 200MBps speeds at night, but it is spotty and is a lot of time 40MBs during the day.  I just did a speed test (speedtest.net) and I was getting 17MBps.

Hello @user_with_slow_internet, Thank you for leaving a comment. Hope you are having a great day. Sorry to hear that you are having intermittent issues with the connection and speed. When running a speed test, are you hardwired or wireless? How many devices do you have connected? Have you checked the connections to the modem to make sure they are tightly secured?

This is a consistent issue across all devices in the home and has been persistent for at least a couple of weeks. We are using Xfinity equipment.

@user_stuart1, thank you very much for taking the time to work with us towards a resolution to your speed problem. Looks like after some general troubleshooting it looks like we had to get a tech involved that replaced some wiring on the inside of your building. I'm glad we could get things back on track! Please enjoy your service and take care!

In my experience, the solution is to do a hard reboot of the modem. In my case it solves the problem for 1-2 months, and then it recurs. A very experienced Xfinity technician identified the slow download speed as a software bug. He told me that upon initialization, Xfinity provisions the modem with software that uniquely identifies your hardware, and provisions you as a customer. For reasons he didn't understand, my modem would "forget" certain parameters, which manifested itself as very slow internet speeds. Thinking that it could be a bad modem, I bought a new identical modem and found that it made no difference. I then returned the substitute and bought a modem from an entirely different manufacturer expecting that the software would be different. That made no difference either. Because in my area Xfinity is so much less expensive than the only other option (Fios), I'm willing to hard reboot every 1-2 months despite the occasional inconvenience. It is a hard problem to troubleshoot because it occurs rarely and randomly; the technician said he would report it but was skeptical that it would ever be fixed. That was about a year ago, and he was right!
