Not sure what is going on with my cisco dpc3941t modem.  The 2.4 and 5.0 wifi shows a strong connection and when I log onto the wifi network I have a solid connection, however, the wifi does not work, it is very slow at best.  But, if I connect to the xfinity hot spot on the modem, it works perfectly.  I have replaced the modem and am still having the problem.  Resetting does not make the problem go away.  Any ideas?

I experience the exact same issue would love to see an explanation from Xfinity.  I use wifi for my phone and texting works much better with the hotspot.

Hi shepjim. I'd be more than happy to look into your internet connectivity issues. When it comes to WiFi speeds we cannot guarantee the same speeds as if you were hard lined into your modem. Please follow this link that will give you  "Tips for Better WiFi Performance" 

 

If you can, please connect a device directly to your modem using a Ethernet cord and trying running a speed test. I would like to at least make sure you are getting the speeds you are supposed to be getting, as well as check the signals on your end to make sure those are good as well.

I have my main computer plugged directly to the modem and the speeds are fine.  It is the wifi speeds that are not working.  Or are extremely sluggish.  The Xfinity hotspot on the router works fine.  Actually we wound up setting up an additional wifi router, which is plugged into one of the LAN connections on the modem and it work fine and is stable.

An F.Y.I.. If you are hanging a stand-alone / separate router off of the gateway device, and the gateway is not in *bridge mode*, you are cascading 2 routing devices which results in an undesirable "double NAT" condition on your home network.

Google "double NAT" for info about it's potential pitfalls.
