slow internet speed due to intermittent connectivity?

We just got Comcast last week. When tested, the speeds are in the 48-52 range, but programs that ran fine on AT&T internet are now running slowly and tablets show multiple internet disconnects which leads to this question. We've replaced the modem and talked with Comcast, but don't know what to do. If this won't work I want to cancel within the 30 day window. Thank you for any insight you can provide.

  1. It might not be just the modem, have you replaced your router? Comcast equipment is known to be very bad, as I've experienced before. Adding a new router can make a night and day difference.,kpid:1247261&gclid=COfo6uDb0coCFdgPgQodx_MN6g I personally have comcast, and while their prices and data caps are awful, it's the only ISP in the area so we don't have a choice. I hope this helps.
  2. Thank you, and now I have to admit that I don't know what we replaced. I assumed what Comcast provided to us to connect us to the internet and phone service (both new this past week) was a modem. Could it be a router? It's an Arris TG1682G model

    The issue is that that unit provides both internet and phone. It's known as a gateway. Unfortunately, if you have VOIP, you would need to buy a telephony equipped modem along with a router. Which can run you ~$200 total. Did comcast tell you that they charge $10 a month for that router? I didn't know for 3 years until I examined my bill. Needless to say, if you want to keep comcast internet service, you should definitely switch out the modem and router. Here are my recommendations. You may want to try using this for your modem and this for your router
  4. Thank you! Of course, they didn't tell us LOTS of things in addition to your highlighted answer above. We also had to pay to run a cable line into our office because the system needs the cable and the phone line together. One last question--when you changed your gateway, did your speeds (not what they say you have, but how the websites are loaded and run which includes the intermittent nature of their service) improve?
  5. Well, with the router I bought, speeds went up by 5 mbps on my ethernet, and drastically improved with my wifi equipped devices. I can't determine how much of an improvement the modem will make, since I myself am still switching it out. However, it is logical to assume that the router will help with the slow speeds and the modem will only improve upon that.
